Description

  This application is a continuation of a pending US Patent Application No. 13 / 903,129 filed May 28, 2013 and is filed with the European Patent Office on June 22, 2012. The priority of application No. 121733261.4 is claimed.

  Aspects of the present invention relate to a compact device for performing beauty treatments such as acne treatment, wrinkle removal, hair removal, rejuvenation, and other applications based on phototherapy. This system includes a detection system that evaluates the exact area to be treated and a multi-wavelength laser or LED that is tuned to optimally treat an undesired cosmetic disorder and is aimed at one or more points from different directions Includes light source.

  In known cosmetic treatment devices, treatment is carried out by irradiating a large area of skin with a large amount of light without distinguishing between healthy skin and the skin to be treated. A typical system for dermatological treatment is intended to perform dermatological treatment by irradiating a large area of skin with a strong light pulse (see, for example, Patent Document 1). The choice of treatment is made by the color characteristics of the skin or hair follicle, and the choice of the treated and untreated areas is made by source wavelength selection in a process called photothermal melting or wavelength dependent light absorption.

  Because light is absorbed by dark objects, the energy of the laser is absorbed at a higher speed and intensity by dark substances in the skin. This dark target substance or chromophore may be naturally derived or artificial. A major disadvantage of this treatment procedure is that large areas of skin are unnecessarily exposed to high levels of intense pulsed light, which can be detrimental.

  For example, conventional laser hair removal systems rely on a large amount of high intensity light being applied to a large area, and hair removal is performed at a wavelength that does not damage human tissue, and the light is transmitted through the skin to the depth of the hair follicle. Then destroy the hair follicles by photothermal melting.

US Patent Application Publication No. 2009/0054880

  Special peripheral lighting systems have been disclosed that greatly increase the contrast because small features on the skin surface are difficult to discern due to lack of contrast, especially when the feature and surrounding skin color are similar Yes.

  Special illumination techniques based on oblique illumination that enhance image contrast are disclosed. This contrast enhancement method is particularly applicable to the identification of small features with low contrast, such as blonde or white hair on pale skin. Illumination enhances contrast by two mechanisms: oblique illumination (approximately 90 degrees with respect to the camera's optical axis) and multiple wavelength illuminations, each from UV to infrared, that give complementary colors to a given feature. Light passing through the glass substrate is reflected only from non-uniform features on the skin surface, and illumination from oblique angles at all zenith angles is diffracted, refracted, and reflected back towards the camera objective lens. Forms an image of a bright sample overlaid with a dark background.

  A special imaging device whose sensitivity matches the light source is used to detect and discriminate the area to be treated from surrounding areas. Optionally, a second visible light source is used to illuminate the skin surface to determine the position and display the image. The selection of the area to be treated is done by spatial discrimination rather than color selection by wavelength.

  The light source to be treated includes a laser or LED of an appropriate wavelength that matches the particular therapeutic application. A dual wavelength laser that can be treated by penetrating the skin or by penetrating local skin is preferred. The laser power of the system is sufficient to generate a beam that can penetrate the epidermis and destroy selected targets. Penetration is a level that destroys the target, such as hair follicles, pigment spots and wrinkles, by puncturing the epidermis locally by choosing the right wavelength to penetrate the skin to the target area This is achieved by increasing the power density. With a special controllable power supply, the treatment light source can be operated in continuous mode or pulsed light mode. The laser beam used for laser rejuvenation and wrinkle removal is aimed at the wrinkle outline. It simultaneously heats the underlying skin called the dermis. This action promotes the growth of new collagen fibers. As the treated area heals, the new skin formed will become smoother and firmer. For acne, the underlying skin is heated using light sources of different wavelengths, typically in the 400 nm region, in combination with longer wavelengths.

  Acne occurs when the body produces excess oil and fluid fluids that are trapped under the surface due to cuticle formation and debris. When this happens, bacteria are generated at an abnormal level, causing infection.

  The laser system is arranged to converge to one or more spots from different directions, generating one or more high-power spots at multiple wavelengths on the one hand and generating a strongly diffusing beam on the other hand Increase safety. A special clever guiding mechanical system is provided to accurately select the area to be treated with micron accuracy.

  One of the unique features of the beauty treatment device of the present invention is that it realizes the performance of the currently marketed system for the above treatment procedure, sometimes surpassing it, while minimizing all the capabilities of beauty treatment. It is integrated in the device that can be held in the hand. This cosmetic treatment device is based on a plurality of light sources, lasers or LEDs, which are focused on the treatment area from different directions. Multiple light sources for therapeutic purposes may be the same wavelength, or may be of different wavelengths, each optimized for different applications. Target selection is performed by a sophisticated illumination system of two wavelengths. The internal light source structure allows the cosmetic treatment device to operate at high peak intensity for effective treatment, and the emission spectrum remains mostly in the near infrared region. The aiming of the plurality of focused beams is performed manually or automatically.

  The above features make the proposed cosmetic treatment device useful for all types of hair because its working principle is based on spatial hair removal rather than selective photothermal melting.

  Another advantage of the proposed cosmetic treatment device is that it displays images of the work area near and around the light source, allowing the user to perform treatment directly even in hidden areas. It is.

  In addition, the high light collection capability and small size allow the use of well-designed small treatment handpieces.

  Many of the disadvantages of conventional cosmetic treatment devices are preferably solved by aspects of the present invention. Some are listed below.

  In conventional systems, a high power light or laser is applied to a relatively large area, and the necessary treatment is usually performed with photothermal melting followed by incidental damage to the surrounding skin. One aspect of the present invention overcomes this disadvantage by directly irradiating the focused laser beam or light to the treatment site without affecting the surrounding skin.

  Some conventional treatments are performed by selective photothermal melting or by limited penetration of the skin that allows penetration of light deep. Another aspect of the present invention provides treatment by spatial perception of the area to be treated, thereby enabling not only photothermal melting but also intensive and powerful treatment with a direct local system.

  In some conventional devices, the illuminated area can only be identified by visible light illumination from above, and the contrast of the image may be low, but in other aspects of the invention, additional peripheral illumination is provided. This improves the contrast of the skin surface features.

  In some conventional devices, the light source is relatively large, requiring large amounts of power and complex power electronics. Another aspect of the present invention provides a small therapeutic laser or LED that requires less power and can be operated with a USB power supply.

  In some conventional devices, the light source is usually one light source per treatment handle, and in the case of a laser handheld device, the light is emitted with a very limited light spectrum of a few nanometers . Another aspect of the present invention overcomes this deficiency by using dual wavelength miniature lasers or mounting several lasers or LEDs on the same treatment laser head to enhance the effectiveness of the treatment.

  Reference will now be made in detail to those embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like elements are designated by like reference numerals throughout. Embodiments will be described below with reference to the drawings to explain the present invention.

  Aspects of the present invention can directly irradiate a focused light beam onto a skin disorder, such as a follicle, a stain, a tattoo particle, a microvessel, etc., and the surrounding skin. Discloses a cosmetic treatment device that treats a disorder with almost no effect on the skin.

  Some aspects of the present invention disclose a cosmetic treatment device that allows recognition of the area of skin to be treated. Obstacle recognition is performed by a dual illumination system, and a specific target recognized for cosmetic treatment is directly irradiated by a plurality of coherent or non-coherent light sources.

  Some aspects of the present invention disclose a dual lighting system in which an additional lighting system is provided in addition to a “regular” lighting system. The so-called regular illumination system illuminates the skin from above and is mounted around the camera lens. This configuration usually provides good illumination for the skin, but the hair and roots are difficult to see due to back reflections. The additional illumination system is attached to the periphery of the system opening, as seen in the associated drawings, to provide illumination parallel to the skin. The features protruding from the skin are strongly illuminated, but the skin remains relatively dark, producing an improved image that emphasizes the features of the hair and outer surface.

  FIG. 1 is a schematic diagram showing a cosmetic treatment apparatus 100 according to an embodiment of the present invention. The imaging device 16 includes a camera system 7 and a small imaging device 3 (see FIGS. 1 and 2). The camera system 7 is a multispectral camera system having sensitivity in the visible spectrum and the infrared spectrum. The small imaging device 3 is preferably a charge coupled device CCD, but this is not necessarily the case. The small imaging device 3 receives an image acquired by the camera system 7 and a user views a visual image of the image acquired by the camera system 7. To be provided. The beauty treatment device 100 is coupled to a regular screen, such as a computer screen, tablet or mobile phone, or TV screen, wirelessly or by USB or by other coupling elements, or analog by a connector cable or other coupling element. • Coupled to the screen. The illumination system 11 is in this example LEDs or small lamps, but is located in the peripheral area of the skin of the person being treated (user or another party). The emitted illumination is mainly parallel to the skin surface, thereby increasing the contrast of various features of the skin surface. Each treatment light source such as a laser module 40 has a laser diode 4 and a condensing optical system 8 and is attached to a small optical bench 6. Each laser diode 4 generates a converging beam 9, which is Aim at the same target point 12 on or below the skin. Each laser diode 4 is accommodated in a housing, and the housing is mounted on a small optical bench 6, and the small optical bench 6 includes necessary electronics (for example, an electronic chip) for driving the laser diode 4.

  The LEDs 4 can have different wavelengths. The cosmetic treatment device 100 comprises a firing button 2 that is exposed and projects outwardly from the outer surface 1 of the cosmetic treatment device 100 (see FIG. 3) and a firing contact 5 that is coupled to the firing button 2 by a coupling element 32. ing. The pulse pattern of the LEDs 4 is determined in advance at a factory, for example, or selected by the user through software accessible by the user. Pressing the firing button 2 moves the firing contact 5 to activate the laser module 40 and generate a predetermined pulse pattern or pulse duration. A special spherical bearing 13 rotates and scans the focused beam on the skin surface. A user who activates the beauty treatment device 100 by himself and performs hair removal or skin rejuvenation, or performs hair removal or skin rejuvenation on another person, the upper part (outer surface 1) of the beauty treatment device 100 around the spherical bearing 13 Move it to make subtle movements of the laser on the skin surface. In FIG. 4, line AA shows a cross section of the cosmetic treatment device 100 (see FIG. 1 for a cross sectional view along AA), and concentric circles show elastic elements sealing the spherical bearing 13. When the outer surface 1 is moved manually around the spherical bearing 13, the LEDs 4 are steered to various positions. The scanning of the target point 12 is performed by manually moving the beauty treatment apparatus 100 around such a pivot.

  The treatment lasers or LEDs 4 are equipped with condensing optics 8 and adjust the beam size by moving the converging beam 9 directed to a specific treatment skin area up and down, after which significant damage to the surrounding skin is achieved. Give local treatment without giving. The recording device 54 is for recording, and marks and records an area that has already been treated by the user.

  The electronic circuit board 10 includes a control unit and a pulse generator. The control unit controls the parameters of the beam that is applied to the skin. Control is provided by a pulse generator to achieve the intensity duration required for a particular cosmetic skin treatment. The pulse generator can be activated by the user pressing the fire button 2, the user can select the output by software stored in the computer device, or the output can be displayed on the TV screen, Control the output with some device.

  5-9 are schematic, perspective, cross-sectional and exploded views, such as FIGS. 5, 6 and 7, showing the operation of the cosmetic treatment device 100 and LEDs 4 according to an embodiment of the present invention, and the focused beam is the epidermis of the skin. FIG. 9 is an exploded view (see FIG. 8) of the skin surface area as it passes through. The imaging device 16 identifies the hair 25 at the position of the hair shaft 26 and, in some cases, the position of the hair follicle 27. The imaging device 16 is a multispectral imaging device sensitive to the infrared spectrum and also identifies the position of the hair follicle 27 under the skin (see particularly FIGS. 8 and 9). The hair follicle 27 may be at the boundary between the dermis and the skin. FIG. 9 is a cross-sectional view of the cosmetic treatment apparatus along the cross-section BB shown in FIG.

  The therapeutic laser light source (LEDs) 4 has a single target point (light collecting point) 12 in this configuration example, and the target point 12 is located below the epidermis level of the skin, and the hair follicle 27 shown in the figure. Or it is provided to target its immediate surroundings (see FIG. 8). Each focused beam 9 penetrates the epidermis from different locations. The focused beam 9 is not yet focused at the skin level and therefore does not damage the epidermis. However, at the approximate position of the hair follicle 27, the three focused beams 9 are matched and each is focused. Eventually, the device is focused to a level below the skin and collects in the spot of hair follicle 27 as shown in detail in FIG.

  Note that if the illumination system 11 is thicker, the target point 12 is not on the skin surface but on the skin surface.

  FIG. 10 shows a portion of the skin with hairs 25 in the skin area, and hair shafts 26 and hair follicles 27 are captured by the camera system 7 and viewed by the imaging device 3 of the imaging system 16. FIG. 11 is a cross-sectional view including the skin surface and the lower skin portion of the patient's body along line CC in FIG. The skin is partially transparent to the camera system 7, the treatment wavelength of the focused beam 9, and the illumination system 11.

  1, 3 and 9, the camera system 7 takes an image of a portion of the skin, and the area of the skin includes hairs 25 with hair shafts 26 and hair follicles 27. As can be appreciated, in this embodiment, the camera system 7 is stationary within the beauty treatment device 100, and when the user wishes to take an image of a different part of the skin, the user is directed to the outer surface of the beauty treatment device 100. 1 needs to be moved. The imaging device 16 uses the small imaging device 3 to form an image of the skin portion and supplies the information to an external display device such as a display panel, computer screen, or other type of screen.

  The imaging device 16 can be seen up to the hair follicle 27 through the transparent surface of the skin. Therefore, the target point of the LEDs 4 can be moved to the position of the hair follicle 27.

  12-16 is an exploded view of the illumination system 11 shown in FIG. FIG. 12 shows a basic configuration of the illumination system 11. The proposed illumination system 11 includes a glass disk (substrate) 18 with an illumination light source 19 at the periphery. The illumination light source 19 outputs light of different wavelengths and can be controlled individually. Different wavelengths can give a higher contrast between the skin surface and the area to be treated (skin features). The light 20 passes through the glass disk substrate 18 in a direction substantially perpendicular to the optical axis 30 of the system, providing oblique illumination to the skin feature to be observed. Here, the light output from the illumination light source 19 advances almost parallel to the skin. The inner opening of the glass disk substrate 18 may be the hollow portion 21 as shown in this figure or may be solid. The lighting system 11 illuminates the skin area just below the periphery of the hollow (the area “inside” the hollow), and the LEDs 4 treat the skin area inside the hollow to solve the cosmetic problems shown there. . 12 is a cross-section of the illumination system 11 taken along line DD of the cosmetic treatment device 100 of FIG. 14 as viewed from the bottom.

  17-20 is an exploded cross-sectional view showing an illumination system 51 according to another embodiment, in which the illumination light source 23 is mounted on the printed circuit board 22 and illuminates the transparent portion 14 having the reflective surface 52. The reflection surface 52 bends and reflects light by 90 degrees, and the light beam 15 exits from the opening of the reflection surface 52 almost parallel to the skin surface. In this way, unlike FIG. 12-16 in which the illumination light source 19 is attached to the periphery of the glass disk substrate 18 and the light exits in parallel with the skin, in FIG. The light is emitted at a right angle, and the reflecting surface bends light 90 degrees so that it is parallel to the skin. 17 is a cross-sectional view of the illumination system 5 (along line EE in FIG. 20), and FIG. 20 is a view of the illumination system 11 of the beauty treatment apparatus 100 as seen from the bottom.

  21-25 show a cosmetic treatment apparatus 200 according to another embodiment of the present invention. In this embodiment, a plurality of pairs of light sources (laser diodes) 64A, 64B, 64C and 64D are mounted on the optical bench 66 and are aimed in the direction directly below the figure so as to be parallel to each other in the same direction. . The optical bench 66 is similar to the optical bench 6 of the above-described embodiment, and includes electronics (for example, an electronic chip) necessary for operating the laser diodes 64A to 64D. The laser diodes 64A-64D are in this embodiment aimed at the area 11 under the skin (under the epidermis 89 and the dermis 90), but just as easily on the surface of the skin (the epidermis 89). You can aim. Laser diodes 64A-64D are paired and each pair is represented by the same letter combination, namely 64A, 64B, 64C or 64D, for a total of four pairs as shown in FIGS. Is installed. There may be fewer or more than four laser diode pairs. A section FF in FIG. 23 of the beauty treatment apparatus 200 is shown in FIG. Each laser diode has a condenser lens 65, which collects the light emitted from the laser diode. Each laser diode 64A-64D exits the corresponding light boom 69A-69D straight down, which is guided by the lens 86 and focused toward the target point or points along the optical axis of the lens 86. . The lens 86 in this example focuses the laser beam boom 69A-69D under the skin, but may alternatively be configured so that the laser beam boom 69A-69D is focused on the skin surface.

  A camera system 67 having an imaging device 63 (in this embodiment it is a charge coupled device) enlarges the area of the skin and schematically shows the epidermis 89, the dermis 90 and the sub-skin area 81. Hair follicle 27 is shown in FIGS. 24 and 25, and laser beams 69A-69D are aimed at it. Each pair of light beams has a different wavelength and is collected by the lens at different points under the skin 11 along the system optical axis, creating multiple focal points along the optical axis (see FIG. 25). This is because the lens 86 bends the light in different amounts depending on the wavelength of the light beam passing through. In general, the higher the wavelength, the farther the target point is from the beauty treatment apparatus 200, and thus deeper into the skin. Since the user cannot determine the exact depth of the hair follicle 27, the chance of being able to remove the hair follicle increases as the target point of the pair of light beams varies along the axis and becomes deeper or shallower under the skin. .

  As described above, a plurality of light source pairs can be configured to emit light beams having the same wavelength, but each pair emits light beams having different wavelengths from the other pairs, but all emit light beams having the same wavelength. It can also be configured as follows. Further, the light beams can be paired at different pulse frequencies, or paired in the visible, infrared (IR), or near ultraviolet (UV) regions, depending on the application / treatment performed by the cosmetic treatment device 200. it can.

  The lens may be a single lens or a multiple lens, for example a double lens, in which case the wavelength can be corrected by the lens system so that all wavelengths are at the same focal point.

  Based on the image received from the camera system 67, the user can target the aim of the light beam 69A-69D, such as the hair 25 and / or hair follicle 27 in this particular example. The beauty treatment apparatus 200 incorporates the special spherical bearing 13 shown in the beauty treatment apparatus 100 of FIG. 1 so that the user can point the target point 12 to the side, but avoids being redundant. I won't touch on this to make it easier to understand.

  The lens 86 is vacant in the center so that the camera system 67 can clearly see the skin portion under the beauty treatment apparatus 200.

  Illumination system 11 is incorporated into this embodiment in the same manner as illustrated and described for beauty treatment apparatus 100, but is not touched to avoid redundancy and for ease of understanding.

  FIGS. 26-32 illustrate a cosmetic treatment apparatus 300 according to yet another embodiment, which incorporates the ability to move the laser focal point across the skin portion of the image without moving the outer surface 301. In this embodiment, the laser diodes 64A-64D and optical bench 66 configuration from the previous embodiment and the lens 96 (which is the same as the lens 86 or lens system used in the previous embodiment). Good) is used. This ability is achieved by tilting the lens 96 about two axes. FIG. 26 shows an external view of a cosmetic treatment device 300 that includes an outer surface 201 and a coupling cable 302 that couples the beauty treatment device to a display and / or computer device. The coupling cable 302 can also be used in the previous embodiments. In any of these embodiments, the display and / or the connection with the computer device may be performed wirelessly in the same manner as the wire connection.

  FIG. 27 shows a cross-sectional view of the lens system (or single lens) 96 along the section GG of FIG. 26 when the lens 96 is in its original untilted position. FIG. 28 is a schematic diagram of the beauty treatment apparatus 300. FIG. 30 shows a cross-sectional view of lens system (or single lens) 96 along section H-H of FIG. 29 when lens 106 is tilted relative to its original untilted position. This lens 96 condenses a plurality of laser light beams 69A-69D emitted by corresponding laser diodes 64A-64D mounted on the optical bench 66 on one or more target points 112 along the optical axis of the lens 96. Let Motors 114 and 115 tilt frames 116 and 117 oriented in two perpendicular directions about axes 120 and 121. For relatively small tilting movements, the camera system 67 corresponds to the frame 116 and 117 even though the outer surface 301 of the beauty treatment device 300 indicates a skin area at a certain location on the person being treated. Rotation about axes 120 and 121 causes the lens to rotate, and this effect causes laser focused beams 69A-69D to be applied to the skin area without any new movement of outer surface 301 of beauty treatment device 300. Scan. The amount of movement is proportional to the tilt of the lens 96. In this example, frames 116 and 117 act as gimbals. In one aspect of the invention, the lens 96 is tilted 3 or 4 degrees.

  FIG. 31 shows the tilted position of the target point 112 when the frames 116 and 117, and thus the lens 96, is tilted with respect to the original position (optical axis) 118 where the lens 96 is not tilted. . FIG. 32 shows in detail the tilting mechanism by the motors 114 and 115 and the two orthogonal shafts 120 and 121 that are the rotation axes of the frames 116 and 117. Here, the frame 117 is glued to the lens 96. The target point 112 is moved away from the original optical axis of the corresponding lens 96 when the lens 96 is in the original start position.

  The lens 96 has a hollow in the center so that the camera system 67 can clearly see the skin portion under the beauty treatment apparatus 300.

  In this embodiment, the user adjusts the lens position so that the light beam 69A-69D is aimed at the hair follicle 27 under the skin in the field of view of the camera system 67, thereby allowing the beauty treatment device 300 Skin features such as hair 25 can be treated without moving the outer surface 301 of the skin. Alternatively, a computer system (not shown) receives an image of the skin portion and uses an algorithm to determine the position of one or more follicles within the skin portion from which the image was generated, and then The motors 114 and 115 can be driven to rotate the lens 106 by the frames 116 and 117 so that the light beams 69A-69D are aimed at the desired position of each follicle in the skin portion. In that way, the user can simply place the cosmetic treatment device 300 on a skin part and the beauty treatment apparatus can remove each hair follicle (and thus hair) on the skin part without doing anything else. Easy to use for the user. The user can even see the release from the hair follicle being treated. By pinpointing the location of the hair follicle and treating only that particular location, you can find the exact location of the hair and focus the entire skin area without focusing on the hair follicle below the skin. Less damage and pain to the skin compared to conventional methods of treatment.

  In this embodiment, the special point bearing 112 as shown in FIG. 1 is not required because the target point 112 can be moved laterally by rotation of the lens 96.

  The lighting system 11 is also incorporated into this embodiment in the same manner as illustrated and described in connection with the beauty treatment apparatus 100, but is not touched to avoid redundancy and for ease of understanding. .

  FIG. 33 is a perspective view showing a lens lateral movement mechanism 122 that replaces the biaxial angular movement mechanism shown in FIGS. 26 to 32, and its function is to direct laser light beams 69A-69D over a predetermined area of skin. Scan to the side. Lateral movement takes place parallel to the skin and the ratio of the movement of the lens 106 to the movement of the laser on the skin is unity. The lens 106 is the same as the previous lens, such as the lens 96, but the mechanical contour is different. Frame 127 holds lens 106 and is attached to nut element 131 (see FIG. 34) and is moved linearly along axis 129 by motor 129 (see FIG. 35). A mechanical frame 128 holds the motor 124 and is attached to another nut (not shown). The linear mechanism can be seen in the enlarged section J of FIG. In FIG. 34, the threaded shaft 132 of the motor 124 engages the nut element 131 to move the nut element 131 so that the frame 127 moves relative to the mechanical frame 128 along the axis 129. Frame 133 holds another motor 125 and a threaded shaft (not shown) engages a nut element (not shown) attached to mechanical frame 128. Similarly, therefore, the motor 125 moves the mechanical frame 128 along the orthogonal axis 130 and moves the lens 106 in a direction perpendicular to the axis 129. The frame 133 is attached to the outer housing of the beauty device 400. In a manner similar to the movement of the target point shown in FIGS. 30 and 31 (but by a different operation from the lens 106), the original light of the lens 106 when the target point 112 is in the original start position. Moved away from the axis.

  FIG. 35 shows the same lens lateral movement mechanism 122 as shown in FIGS. 33 and 34, but with previous embodiments such as the optical bench 66, camera system 67 and one or more laser target points 112. However, there is shown a cosmetic treatment apparatus 400 according to another embodiment of the present invention, including some additional features that were present.

  In this embodiment, the user adjusts the position of the lens 106 so that various features of the skin, such as the hair 25, are transmitted to the light beam (s) 27 under the skin within the field of view of the camera system 67. By aiming 69A-69D, treatment can be performed without moving the outer surface (not shown) of the beauty treatment apparatus 400. Alternatively, a computer system (not shown) receives an image of the skin portion and uses an algorithm to determine the position of one or more follicles within the skin portion from which the image was generated, and then The motors 124 and 125 can be driven to move the lens 106 laterally by the frame 127 and mechanical frame 128 so that the light beams 69A-69D are aimed at the desired location of each follicle in the skin portion. . As such, the user can simply place the beauty treatment device 400 against a skin portion and the beauty treatment device 400 can remove each hair follicle (and thus hair) on the skin portion without doing anything else. Can be used easily by the user. The user can even see the release from the hair follicle being treated. By pinpointing the position of the hair follicle 27 and treating only a specific position, the entire skin part can be found without finding the exact position of the hair or focusing on the hair follicle under the skin. Compared to conventional methods of treating the skin, there is less damage and pain to the skin.

  In this embodiment, one or more target points 112 can be moved laterally by rotation of the lens 96 so that no special spherical bearing 13 as shown in FIG.

  The lighting system 11 is also incorporated into this embodiment in the same manner as illustrated and described in connection with the beauty treatment apparatus 100, but is not touched to avoid redundancy and for ease of understanding. .

  Thus, an apparatus and method for a beauty treatment apparatus has been disclosed. The apparatus includes a plurality of focused beams that are selectively aimed at a skin area to be treated. Some aspects of the present invention provide a cosmetic treatment in which a target skin area is selected using a plurality of wavelength light sources combined with a sufficient imaging device and the target skin area is treated using a combination of appropriate laser light. Regarding the method. Treatment is performed by aiming a focused light source or laser beam into or under the skin, which penetrates and destroys the hair follicles between and under the skin. Have enough power to treat acne and treat skin disorders in or under the skin. More particularly, the various aspects of the present invention relate to a small cosmetic treatment device that can perform non-contact treatment on a limited area of human skin, including hair follicles, acne glands, tattoo removal, wrinkles, and age spots. Relating to the treatment of skin disorders, rejuvenation, and other epidermis treatments. The imaging device can recognize the area to be treated and use an effective illumination device that illuminates the area of the skin to be treated from the periphery to increase the contrast between the skin and skin surface lesions.

  A conventionally known method uses a relatively large light source that irradiates a large amount of light on a large skin area in a specific wavelength range, and the light source can be selectively treated by photothermal melting. For example, hair removal is based on the principle of avoiding significant damage to surrounding tissue and skin while selectively heating and destroying the hair follicles. Hair follicles are selected by photothermal melting, a method based on the fact that the hair absorbs more light because it is darker than the surrounding skin tissue, and a similar mechanism works on the skin. He is also working on other treatments such as tiny veins that are raised. Thus, the hair is automatically selected by the light source because of its dark color and large absorption coefficient. On the other hand, hair or other skin disorders that are brighter than the surrounding skin area are difficult if not impossible to treat with conventional methods. It is of the present invention to provide a different method of destroying hair follicles with the collected light energy based on the spatial selection of hair follicles or other targets and causing little or no damage or exposure to surrounding skin or tissue It is the objective of the beauty treatment apparatus concerning embodiment.

  One of the major limitations of existing methods is to use a photothermomelt effect based on the color difference between normal skin and the area to be treated, in which case the basic requirement is that the skin is a hair follicle. It is significantly brighter than glands and glands and is basically transparent to the wavelengths used. This is the main reason why light-colored hair (such as blondes) and white hair are lighter than the surrounding skin, making it almost impossible to treat using conventional devices and methods. It is also an object of the present invention to provide a method that is free from such limitations of the prior art.

  Some aspects of the present invention generally detect the position of a small skin area to be treated and the light from the light source is focused on this specific area (on or under the skin) to surround the surrounding skin. The present invention relates to a cosmetic treatment apparatus and method that does not affect or damage an area.

  While a few embodiments of the present invention have been illustrated and described, modifications may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims. Will be apparent to those skilled in the art.
