[Figure 8] (A) and (B) are explanatory diagrams illustrating the condition before and after the procedure. [Modes for carrying out the invention]

[0016] The embodiments will be described in detail below with reference to the attached drawings. In this example, already publicly known technologies will not be explained. Furthermore, the structures and methods described are illustrative examples for realizing the technical idea of ​​the invention, and the technical idea of ​​the present invention is not limited to those described below. The technical idea of ​​the present invention can be modified in various ways within the scope of the matters described in the claims. In particular, it should be noted that the drawings are schematic and do not represent reality. In this example, the direction of a person's height when standing upright is defined as the vertical direction, the direction perpendicular to this vertical direction and viewed from the front of the person is defined as the front-to-back direction, and the direction perpendicular to both the vertical and front-to-back directions is defined as the left-to-right direction.

[0017] Refer to Fig. 1. An eyebrow extension 1 is attached to the natural eyebrows 3 growing on the forehead 5 of the head. The eyebrow extension 1 has an adhesive (also called glue) 7 at the root. The eyebrow extension 1 is brought into contact with the natural eyebrows 3, and the adhesive 7 is irradiated with light from an LED (light-emitting diode) 9a to be cured.

[0018] Refer to Figs. 2(A) and (B). They show the shapes of cross-sections A and B - A, B in Fig. 1. Fig. 2(A) shows a method of applying the eyebrow extension 1 in the left - right direction of the natural eyebrows 3. Fig. 2(B) shows a method of applying the eyebrow extension 1 in the upward direction of the natural eyebrows 3.

[0019] The eyebrow extension 1 is a technique of curing a dedicated adhesive 7 with the light of an LED 9a and attaching an extension to the eyebrows 3. It cannot be attached to areas where the natural eyebrows 3 do not grow. Since the adhesive 7 is completely cured in 2 - 3 seconds by irradiating the light of the LED 9a, the onset of allergies is reduced. Also, a beautiful finish can be maintained for a long time. It is resistant to sweat, water, and oil components, so one can wash their face and take a bath immediately after the procedure, and oil cleansing can also be used.

[0020] The ordinary adhesive has a cyanoacrylate main component, and there are various types such as ethyl and butyl among them. The irritation felt during attachment is a phenomenon caused by the volatilization of the acrylic resin - based component cyanoacrylate contained in the glue component, resulting in the generation of formaldehyde.

[0021] The adhesive 7 for the LED 9a of the present invention can be cured faster than ordinary adhesives by blending cyanoacrylate and a photoinitiator. Therefore, the emission of formaldehyde can be minimized, and the risk of the onset of allergies can be suppressed.

[0022] The curing process takes 2 seconds and complete curing takes 10 seconds. In other words, the process is finished by irradiating each eyebrow for 10 seconds. Complete curing means that it is safe to get the extensions wet after application. The time required for complete curing varies depending on the adhesive, and getting the extensions wet before they are fully cured will slow down the curing process and can cause whitening and reduced durability.

[0023] Eyebrow extension 1 in this example maintains a beautiful finish for a long time. Specifically, because it hardens instantly, the holding power is increased, the adhesive 7 is less prone to deterioration, and it lasts longer than regular eyebrow extensions. Furthermore, it hardens in the desired direction without wobbling during application, allowing for an ideal design. While there are individual differences depending on eyebrow condition and lifestyle, compared to the typical 1-2 weeks of regular eyebrow extensions, this method lasts for approximately 2-4 weeks, indicating a relatively longer duration.

[0024] To shorten treatment time, the adhesive hardens one strand at a time, reducing tangling between adjacent hairs and vellus hairs, thus shortening the checking time. Furthermore, since the adhesive hardens in 2-3 seconds, speedy treatment is possible.

[0025] The user benefits include a lower risk of allergic reactions. Those who had given up on eyebrow extensions due to irritation from adhesive 7 can reduce the risk of problems. Also, bathing, going to the gym, and using saunas are possible immediately after the procedure. With regular eyebrow extension procedures, it was not possible to get wet until more than an hour had passed since the adhesive had fully cured, but with the LED9a eyebrow extensions in this example, they are fully cured, so there is no need to worry about post-procedure plans. Oil cleansing can be used, and with regular adhesives, extensions can easily fall off depending on the type of oil cleanser, but the LED9a eyebrow extensions are resistant to oil components, so there is no need to worry about cleansing or cosmetics. The eyebrow extensions last longer, and variations in design are reduced. The extensions remain in place well until the next procedure, and the ideal eyebrows last for a long time. High-speed procedure means that the procedure time is shortened due to the fast curing time, resulting in a more comfortable experience.

[0026] Refer to Figure 3. In terms of wavelength classification, the wavelength of the light used in the eyebrow extension 1 of LED9a is visible light in the range of 395nm to 400nm.

[0027] Visible light (LED) refers to electromagnetic waves that the human eye perceives as light, ranging from approximately 380 nm (violet light) to approximately 780 nm (red light). The color varies depending on the wavelength, and in order of increasing wavelength, they are perceived as "violet, indigo, blue, green, yellow, orange, and red."

[0028] When using LED9a lights, it is important to note that while LED9a (visible light) is not harmful to the human body, it must be used appropriately. Excessive light entering the eyes can damage the retina and cause burns. Therefore, practitioners should wear protective glasses, and light-blocking tape (13) should be applied to the eyelids of users to protect their eyes. Continuous use of LED9a can cause vision loss and eye strain. Therefore, a 5-10 minute break should be taken after each treatment, and the eyes should be rested by closing them. Continuous use at too close a distance can cause problems such as blemishes and sunburn. The appropriate distance for use varies depending on the type of light.

[0029] Refer to Figures 4(A), (B), and (C). As shown in Figure 4(A), take more adhesive 7 than usual and create a ball shape at the base of the eyebrow extension 1. Ensure that the LED 9a light does not shine on the adhesive 7 before application, as this can cause deterioration. The light from the LED arm lights and LED ring lights on the cart can also cause deterioration, so adjust the angle of the top lid of the VLED glue tray so that the light does not shine on the adhesive, and be careful not to bring it too close to the light. Note that in Figure 4(B), there is too much adhesive 7L, resulting in a long bonding time, and in Figure 4(C), there is too little adhesive 7S, resulting in insufficient bonding strength.

[0030] Refer to Figure 5. The LED irradiation unit 9, which has an LED 9a built in, is supported by the holding member 11. The irradiation is performed at a distance of 15 cm or more perpendicular to the eyebrows. Note that this may vary depending on the light. The eyebrow extensions 1 are attached to the existing eyebrow hairs 3, so they are not attached to the skin. However, since they are attached to areas close to the skin, such as fine hairs, communication is conducted in advance to ensure that the user understands the procedure, precautions, and aftercare, by explaining the user's skin condition, physical condition, usual skincare routine, the procedure itself, and other details.

[0031] LED9a's eyebrow extensions 1 are suitable for users who: have thin eyebrows; have sparse eyebrows; want thicker eyebrows; want natural-looking eyebrows; want three-dimensional eyebrows that cannot be achieved with permanent makeup; want natural-looking eyebrows that do not come off even when sweating; and want to shorten their makeup time.

[0032] When choosing eyebrow extensions, match them to the color and thickness of your natural eyebrows. If your eyebrows are bleached, match the extensions to that color. If you have sparse or uneven eyebrows, a thinner thickness is appropriate. Since eyebrows usually grow parallel to the skin or slightly upward, I or J curls are the main choices. In very rare cases, if the extensions are applied to hairs that grow upward, a C curl may be used.

[0033] As a precaution, check whether it can be attached to the user's natural eyebrows (skin condition, etc.). Avoid attaching it to fine, downy hairs as it will easily fall off. Check for sparse or missing areas. Confirm with the user where they want to add hair and check if it can be attached. Select from sample sheets or reference photos.

[0034] Refer to Figure 6. This is the procedure for eyebrow extensions 1. First, in step S01, cleansing is performed. The pre-treatment agent removes oil and dirt from the eyebrows. If makeup is being worn, cleanse first with the pre-treatment agent.

[0035] Step S02 is protection. Apply UV lotion around the eyebrows.

[0036] Step S03 involves designing the brow. Mark the points where the extensions will be attached (brow head, arch, and tail). If waxing is used, the process should be done in the following order: design, waxing, cooling, cleansing, and protection.

[0037] Step S04 involves taping. Apply protective tape to the upper eyelid. Cut the tape in a rounded shape on the eyebrow side to match the bone structure.

[0038] Step S05 involves setting up. Position the light's irradiation area on the eyebrow. Attach the adhesive paper to the adhesive tray and dispense the adhesive onto the adhesive paper in a dome shape. Shake well before dispensing the adhesive. The recommended interval for changing the glue during treatment is approximately 30 minutes. Replace the adhesive paper with a new one for each user.

[0039] Step S06 is for attachment. Apply a small amount of adhesive 7 to the base of the eyebrow extension 1. Rub the adhesive 7 once or twice at a position 0.5 mm away from the base of the natural eyebrow 3 to allow it to adhere. Be careful not to rub too hard. Once the direction of the eyebrow extension 1 is set, press the foot pedal and shine LED 9a on it for 2 seconds.

[0040] In Step S07, complete curing is required. Once one eyebrow has been attached, shine the LED9a light on it for 10 seconds to allow it to fully cure. Do the same for the other eyebrow and allow it to fully cure.

[0041] Step S08 is to remove the tape. While holding the skin down with a cotton swab moistened with purified water, peel off the protective tape.

[0042] Attach the glue paper to the glue tray and dispense the gel remover onto the glue paper. Replace the glue paper with a new one for each user. Do not use remover or other solvents directly on the LED glue tray. When removing eyebrow extension 1, scoop up the remover with tweezers and apply it to the adhesive part of eyebrow extension 1 to be removed. Be careful not to get the remover on other eyebrow extensions 1, natural eyebrows 3, or skin. Leave it for about 2 minutes to allow it to set, then remove eyebrow extension 1. After thoroughly wiping off any remaining remover with a dry cotton swab, wash with a pre-treatment solution.

[0043] Refer to Figures 7(A), (B) and 8(A), (B). Figure 7(A) shows the eyebrows before treatment, and Figure 7(B) shows them after treatment. Similarly, Figure 8(A) shows the eyebrows before treatment, and Figure 8(B) shows them after treatment. It can be seen that the eyebrows are properly shaped after treatment.

[0044] Although embodiments have been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims. Furthermore, it is possible to combine all or more of the components of the embodiments described above. [Explanation of symbols]
