JP6230855B2 - Eyelash extension attachment method and surgical instrument for eyelash extension - Google Patents

Description

  The present invention relates to an attachment method for eyelash extensions. In particular, the present invention relates to an attachment method for improving the adhesion durability between the ground eyelash and the eyelash extension. The present invention also relates to a surgical instrument for an eyelash extension, and more particularly, to a surgical instrument for an eyelash extension for improving adhesion persistence between a ground eyelash and an eyelash extension.

  False eyelashes are one of the items that give the eyelashes length and volume to create a larger, beautiful and attractive eye. False eyelashes can give a length and volume to the user's eyelashes by putting together a plurality of artificial eyelashes, providing an adhesive part at the end thereof, and attaching the adhesive part to the user's eyelid (for example, Patent Documents 1 and 2). False eyelashes adhere to the user's skin, so the wearing feeling is poor, and in some cases the skin may be rashed.

  On the other hand, in recent years, an artificial eyelash called a so-called eyelash extension (hereinafter referred to as an “eyelash extension”) having a volume substantially the same shape and length as a single eyelash has been proposed. (For example, Patent Document 3). This eyelash extension (artificial eyelash) does not adhere to the eyelids, but directly adheres to the eyelashes using an adhesive, so that the wearing feeling is good and there is little risk of skin irritation. In addition, since the eyelash extensions are bonded one by one to each eyelash, it is possible to give the eyelash length and volume with a natural feel compared to false eyelashes.

  Since the eyelash extension is attached to the eyelash (ground eyelash) using an adhesive, it is possible to make it difficult to remove the eyelash extension by increasing the adhesive strength of the adhesive.

In addition, this invention is not limited to the following embodiment.

  An eyelash extension 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The eyelash extension 100 in this embodiment is an artificial eyelash that extends the length of the user's eyelashes. In the present embodiment, the eyelash extension (or eyelash for extension) is referred to as “eyelash extension”.

  FIG. 1 is a perspective view illustrating a configuration of an extension 100 according to the present embodiment. 2A to 2C are views for explaining a method of attaching the eyelash extension 100 of the present embodiment to the eyelash 50. FIG. FIG. 3 is a view showing a state in which the eyelash extension 100 is attached to the upper eyelash 50.

  The eyelash extension 100 according to this embodiment includes an artificial eyelash main body 10 having a tip portion 11 and a terminal portion 15. In the configuration of the present embodiment, the artificial eyelash body 10 is made of resin. Specifically, the artificial eyelash body 10 of the present embodiment is composed of chemical fibers. As resin (chemical fiber) which comprises the artificial eyelash main-body part 10 of this embodiment, polybutylene terephthalate, polyester, an acryl, vinyl chloride, nylon can be mentioned, for example. The artificial eyelash body 10 of this example is made of polybutylene terephthalate (PBT), but may be made of other resin materials.

  Moreover, the artificial eyelash main-body part 10 may be comprised from the colored material other than black. The artificial eyelash body 10 can be made into, for example, dark brown, purple, blue, pink, silver, green, light orange, light gold, red, wine red, white, yellow, etc. Can be realized. The colorant (or dyeing agent) includes natural dyes and synthetic dyes as well as fluorescent dyes.

  Moreover, you may use the thing of a natural material for the artificial eyelash main-body part 10 of this embodiment other than resin. For example, the artificial eyelash body 10 is animal hair (for example, mink hair), but other animal hair may be used. In addition to the resin-derived eyelash extensions, animal-derived materials (typically human hair, silk, etc.) and plant-derived materials (typically cotton) in addition to the animal hair listed here. Can also be used. Moreover, it is also possible to use the artificial eyelash main-body part 10 comprised from the chemical fiber containing protein.

  The artificial eyelash body 10 of this embodiment has an eyelash shape. Specifically, the diameter (here, the diameter) of the distal end portion 15 of the artificial eyelash body 10 is larger than the diameter (diameter) of the distal end portion 11. The artificial eyelash main body 10 is slightly curved, and the top of the tip 11 is sharp. The length of the artificial eyelash body 10 of the present embodiment is, for example, 5 mm to 20 mm, and the diameter (or thickness) of the end surface 15a of the end portion 15 is, for example, 0.07 mm to 0.3 mm. In the eyelash extension 100 of the present embodiment, an adhesive (glue) is attached to the end portion 15. The eyelash extension 100 is adhered and fixed to the user's eyelashes by an adhesive.

  In addition, the shape of the artificial eyelash main-body part 10 of this embodiment is not limited to what was shown in FIG. 1, The artificial eyelash main-body part 10 may be a flat shape. Or the terminal part 15 of the artificial eyelash main-body part 10 may deform | transform circularly. Furthermore, the surface of the artificial eyelash body 10 may be shaved.

  Next, a method for attaching the eyelash extension 100 of the present embodiment to the eyelash 50 will be described with reference to FIGS.

  First, as shown in FIG. 2A, the application unit 22 including the application solution 30 is brought into contact with the eyelash 50 of a user (human) 55 to apply the application solution 30 to the eyelash 50. In this example, the applicator is a cotton swab 20 and the applicator 22 is the tip of a swab shaft 21. By rubbing the surface of the eyelash 50 with the application part 22 of the cotton swab (applying device) 20 (see arrow 65), the component in the coating solution 30 (adhesion durability increasing component) can be applied to the surface of the eyelash 50. it can.

  The coating solution 30 of this embodiment is a solution containing at least one component selected from the group consisting of silver, platinum, gold, silk, keratin, and acrylate copolymers. More specifically, the coating solution 30 of the present embodiment includes a nano-sized metal (such as silver particles), a hydrolyzed low-molecular protein (such as silk), or a polymer copolymer (an acrylate copolymer). Contains at least one of the ingredients. The component (such as silver) contained in the coating solution 30 of the present embodiment has a size that penetrates into the gap of the cuticle of the human eyelash 50. Moreover, the component contained in the coating solution 30 of this embodiment functions as a component for increasing the adhesive durability of the adhesive.

  The component (adhesion sustaining power increasing component or adhesion auxiliary component) contained in the coating solution 30 in the present embodiment is, for example, a solution containing silver nanoparticles. The nanoparticle of this embodiment is a microparticle of 1 micron (1000 nanometers) or less, for example. Examples of the solution containing silver include a solution containing silver nanoparticles, a silver colloid solution, and silver ion water. The silver ion (Ag +) is a silver ion that exists as a cation in which electrons are removed from silver (Ag) as an atom, and is approximately the same size as a silver atom and is a so-called about 200 picometers. The size of the atom. Silver nanoparticles are particles with silver in the order of nanometers. It is also possible to use silver nanoparticles in which finely divided silver ions are held in alumina silica, which is a mineral. The colloidal silver particles are colloidal silver particles. For example, the colloidal silver particles are semipermanently held in a deionized electrolyte solution (colloidal state). The diameter of the silver colloidal particles is, for example, 0.0001 μm, and in this case, the diameter corresponds to 1 / 800,000 of the hair thickness (80 μm).

  Since silver ions have a function as an antibacterial agent, the coating solution 30 containing silver ions can have an antibacterial effect. Silver ions strongly adsorb to various bacterial cells, and can be killed by blocking bacterial cellular enzymes. Therefore, bacterial growth can be controlled by silver ions. In addition, silver ions have a relatively strong antibacterial effect and are extremely safe for the human body. Has an advantage that does not substantially occur.

  In addition to the solution containing silver, the coating solution 30 in the present embodiment is, for example, a solution containing gold (gold nanoparticles) (for example, a gold colloid solution) or a solution containing platinum (platinum nanoparticles) (product name: Platinum Gensui 500 (manufactured by Inovex Co., Ltd.) can be used. The solution containing platinum is, for example, a platinum colloid solution. The colloidal platinum solution contains colloidal particles formed by fine platinum particles. The particle size of the gold colloid solution, platinum colloid solution, and silver nanosolution is 1 μm (1000 nm) or less. In the present embodiment, the nanoparticle may refer to a particle having a particle size of nano-order (for example, 1 to 100 nm or 1 to 1000 nm), and may include particles of 1 nm or less. These nanoparticles may exhibit different properties from solid (bulk) materials of general size due to their extremely large specific surface area, etc. As one of their properties, antibacterial properties It can be used as an agent.

  In addition, when the component (adhesion sustaining power increasing component) contained in the coating solution 30 in the present embodiment is silk, the silk is low molecular silk (hydrolyzed silk). Here, the low molecular silk means a low molecular silk compared to a non-hydrolyzed high molecular silk, and is not defined by a specific molecular weight. In addition, it is preferable that low molecular silk is a thing of the dimension which penetrates into the crevice between cuticles of human eyelashes 50. Furthermore, keratin (low molecular keratin, hydrolyzed keratin) can be used as a low molecular protein in addition to low molecular silk. In addition, acrylates copolymers can be used. The acrylate copolymer is a copolymer composed of two or more monomers of alkyl acrylate (C1-C4), alkyl methacrylate (C1-C4), acrylic acid or methacrylic acid.

  After the application solution 30 is applied to the eyelash 50, as shown in FIG. 2A, a part of the eyelash extension 100 (artificial eyelash body 10) of this embodiment is grasped by the tweezers 60, and the end 15 With the adhesive 17 applied thereto, the eyelash extension 100 is brought close to the eyelash 50. Although the adhesive 17 is usually applied to the eyelash extension 100, the adhesive 17 may be applied to the eyelash 50.

  Next, as shown in FIG. 2B, the adhesive 17 of the eyelash extension 100 is attached to the eyelash 50 so that the eyelash extension 100 is in close contact with the eyelash 50. Then, when the adhesive 17 is cured and the antibacterial eyelash extension 100 is fixed to the eyelash 50, the tweezers 60 are removed as shown in FIG. 2C, and the attachment of the eyelash extension 100 is completed. This operation is performed for each eyelash 50.

  In the method for attaching the eyelash extension 100 according to the present embodiment, the coating solution 30 containing at least one component selected from the group consisting of silver, platinum, gold, silk, keratin and acrylate copolymers is used for the eyelash (ground) of the human 55. Apply to eyelashes 50. Thereafter, the artificial eyelash main body 10 constituting the eyelash extension 100 is fixed to the eyelash 50 of the human 55 via the adhesive (glue) 17. As a result, the component of the coating solution 30 enters the gap between the cuticles of the eyelashes 50 of the human 55, so that lipid or cosmetic dirt is attached to the ground eyelashes 50, and the eyelashes 50 and the adhesive (glue) 17 Even when the adhesive force between the two is reduced, the component of the coating solution 30 can improve the affinity with the adhesive 17. Therefore, the adhesion persistence (adhesion duration) between the ground eyelash 50 and the artificial eyelash main body 10 (eyelash extension 100) can be improved.

  As described above, according to the method of the present embodiment, the adhesion durability between the ground eyelash 50 and the artificial eyelash main body 10 can be improved, so that the adhesion is weaker than the existing adhesive (17). Even if the agent (17) is used, it is possible to maintain the adhesion persistence between the ground eyelash 50 and the artificial eyelash body 10. Accordingly, the types of adhesives 17 that can be used can be expanded, and as a result, it is possible to avoid a highly irritating adhesive (17) that is likely to have an effect such as skin irritation to the user 55, and therefore The comfort of the person 55 using the eyelash extension 100 can be increased. Of course, it is not necessary to use solvent-based primers that are rarely used in industrial and household adhesives, so even if it is not harmful to the human body, eyelash extension 100 and ground eyelash 10 It is possible to extend the adhesion persistence (the period until both come off).

  2 (a) to 2 (c), the application solution 30 is applied to the eyelash 50, but the application solution 30 can be applied to the artificial eyelash body 10 (eyelash extension 100). In that case, even when lipid or cosmetic dirt is attached to the artificial eyelash body 10, the component of the coating solution 30 can improve the affinity with the adhesive 17. The adhesion persistence between 50 and the artificial eyelash body 10 can be improved.

  FIG. 3 shows a state where the eyelash extension 100 is attached to each of the upper eyelashes 50. As shown in FIG. 3, the eyelash extensions 100 are attached to many eyelashes 50. When the adhesion persistence (and / or adhesive strength) of the eyelash extension 100 is weak, a part of the eyelash extension 100 can be removed in a short period of time. Therefore, the technical significance that each eyelash extension 100 cannot be removed for a long period of time due to the increase in the adhesion persistence (and / or adhesive strength) of the eyelash extension 100 is very large.

  FIG. 4 is an enlarged view schematically showing a state in which the component (adhesion durability increasing component) 40 enters the gap 48 of the cuticle 46 on the eyelash surface 43 in the ground eyelash 50 and is fixed there. In addition, this figure is shown in an image, and the component (adhesion durability increasing component) 40 is not necessarily attached to the eyelash surface 43 in this way.

  5 (a) and 5 (b) show an instrument having an application part 22 in a solution (application solution) 30 containing a component (adhesion durability increasing component) 40 such as metal particles (or silk) such as silver. It is a figure explaining the process of immersing (cotton swab) 20. FIG.

First, as shown to Fig.5 (a), the container 35 containing the solution (coating solution) 30 containing the component (adhesion sustaining power increasing component) 40 like silver is prepared. In this example, a solution containing silver nanoparticles (silver nanosolution), a silver colloid solution, and silver ion water. However, not only silver solution,
It may be a solution of any of platinum, gold, silk, keratin and acrylate copolymers, or any mixture thereof.

  The solvent of the coating solution 30 is often water, but can include an alcohol (eg, ethanol), a ketone solvent (eg, acetone), and / or a surfactant. In the coating solution 30, when water and / or ethanol are the main components, it is preferable because there is little adverse effect on human skin. In addition, among the various components 40, what kind of particle size / size is used, what concentration, what kind of solvent / additive of the solution 30 is used (or how it is used in combination) ) Is determined by the adhesive 17 and the eyelash extension 100 (artificial eyelash body 10) to be used, and a suitable material may be adopted accordingly.

  A coating device 20 having a coating unit 22 is also prepared together with the coating solution 30. In this example, the applicator 20 is a cotton swab, but is not limited thereto. For example, a brush or the like can be used. Alternatively, the application solution 30 can be applied to the eyelashes 50 using an instrument such as a dropper.

  Next, as shown in FIG. 5B, the coating part 22 is put in the coating solution 30 so that the coating part 22 contains the coating solution 30. The application portion 22 in this example is made of natural fibers such as cotton, but may be made of artificial chemical fibers or may be made of a porous material such as sponge. Good. After the application solution 30 is included in the application part 22, as shown in FIG. 2A, the application part 22 can be brought into contact with the eyelash 50 to adhere the component 40 to the surface of the eyelash 50. it can.

  Furthermore, as shown in FIGS. 6 (a) and 6 (b), the application tool (treatment instrument) of the present embodiment can have a bottle shape 31 in which the application part 22 and the container 35 are integrated. .

  FIG. 6A shows a state in which the lid portion 25 of the bottle-shaped application tool (treatment device) is opened. On the other hand, FIG.6 (b) has shown the state which showed the cover part 25 of the bottle-shaped application tool (treatment instrument).

  The surgical instrument 31 according to the present embodiment includes a container main body portion 35 and a lid portion 25. A coating solution 30 is stored in the internal space 32 of the container main body 35. An application unit 22 is attached to the lid unit 25.

  The container main body portion 35 of the present embodiment has a bottle shape, and a bin mouth portion 34 having an opening 33 into which the coating solution 30 can be introduced is formed on the upper portion of the container main body portion 35. In addition, a lid 25 that closes the opening 33 is attached to the bin opening 34. The container body 35 of the present embodiment is made of a plastic material (for example, high-density polyethylene, polypropylene, polyethylene terephthalate (PET)), or glass. From the viewpoint of not being damaged, the container body 35 is preferably made of a plastic material.

  In the configuration of the present embodiment, the application unit 22 that applies the application solution 30 is attached to the lid unit 25 via the support rod 21. The application unit 22 is a member such as a brush or a brush pen. In the illustrated example, the application part 22 is attached to the tip of a support bar 21 extending from the inside of the top surface of the lid part 25. That is, the application part 22 is fixed to the lid part 25 by the support rod 21 that supports the application part 22. Therefore, the application solution 30 can be applied to the eyelash 50 by holding the lid portion 25 by hand and bringing the application portion 22 located at the tip of the support rod 21 into contact with the eyelash 50.

  In the surgical instrument 31 of the present embodiment, screw portions (26, 36) are formed on the outer surface of the bin mouth portion 34 and the portion 26 corresponding to the outer surface of the bin mouth portion 36 of the lid portion 25, respectively. . Therefore, after inserting the support rod 21 of the lid portion 25 into the opening portion 33 of the bin mouth portion 34, the lid portion 25 is fastened to the bin mouth portion 34, whereby the surgical instrument 31 ( Alternatively, the container body 35) can be sealed. In this sealed state, the application solution 30 in the container main body 35 does not leak to the outside when the surgical instrument 31 is moved.

  Furthermore, although the thing of the bin-shaped structure was shown in FIG. 6, the treatment instrument (or container main-body part) of this embodiment is not restricted to such a thing. For example, the treatment instrument of the present embodiment may have a pen type configuration as shown in FIG.

  In the surgical instrument 70 shown in FIG. 7, the container main body 71 that stores the coating solution 30 has a cylindrical shape. The application part 72 is disposed at the tip of a conical part 73 extending from the container main body part 71. In this example, the application unit 72 is configured like a brush part at the tip of a brush pen. The inside of the container main body 71 and the application unit 72 are connected, and the application solution 30 stored in the container main body 71 is sequentially supplied to the application unit 72. The coating solution 30 can be applied to the eyelashes 50 by the coating unit 72 to which the coating solution 30 is sequentially supplied.

  A sealing portion (bottomed cylindrical member) 77 for sealing the rear end opening of the container main body 71 is provided at the rear end of the container main body 71. When the sealing portion 77 is removed, the rear end opening of the container main body 71 is exposed, and the coating solution 30 can be filled from the rear end opening. In the illustrated configuration example, a cap portion 75 that accommodates the conical portion 73 and the application portion (brush portion) 72 is attached. In this example, screw portions (73a, 75a) are formed on the outer surface of the conical portion 73 and the inner surface of the cap portion 75, and the cap portion 75 is rotated with respect to the conical portion 73 so that they are fitted together. Can be made.

  The cap part 75 may be a system that can be fixed by being inserted along the major axis direction of the container main body 71 instead of being rotated and fitted into the conical part 73. Further, the sealing portion 77 may be fixed to the container body 71 by a threaded rotation method, or may be fixed by another method (for example, a method of inserting along the major axis direction of the container body 71). May be. In the surgical instrument 70 shown in FIG. 7, the container body 71 has a cylindrical shape, but is not limited thereto, and other shapes (such as a hexagonal cylinder) can be employed.

  The container main body 71 of the present embodiment is made of resin, but the container main body 71 may be transparent so that the coating solution 30 stored therein can be seen. Alternatively, the container body 71 may be made of an opaque material, and a part of the container body 71 may be transparent so that the remaining amount of the coating solution 30 can be recognized.

  This pen-type surgical instrument 70 is convenient because the application solution 30 can be continuously applied to the eyelashes 50. Further, since the surgical instrument 70 has an elongated shape, it does not take up a large storage space, so that it is convenient to store and carry.

  The inventor of the present application conducted an experiment to confirm the adhesion persistence of the coating solution 30 (component 40) in the present embodiment. The results are shown in FIGS.

  In this example, for 10 subjects (A to J), 30 eyelash extensions with one eye were attached to the left and right, and then the adhesion persistence was evaluated by the remaining number of eyelash extensions after 14 days.

  Specifically, after washing human eyelashes, a coating solution 40 containing component 40 (each sample: Examples 1 to 7) is applied to human eyelashes, and then the eyelash extension is attached with an adhesive. It was. As the adhesive, an adhesive mainly composed of ethyl cyanoacrylate (abbreviation: VBPS) was used in common. As the eyelash extension (artificial hair), an artificial eyelash (abbreviated as KSMIX) made of polybutylene terephthalate was commonly used. Since the adhesive and the eyelash extension are typical ones, other adhesives and eyelash extensions used in the eyelash extension industry can be used as an index based on this adhesive.

  Here, Sample Example 1 is purified water, which was used as a placebo (placebo, control), and this result was used as a reference. Example 2 is a water + acrylate copolymer coating solution. Example 3 is a coating solution of water + silver (silver nanoparticles, also referred to herein as “low molecular silver”). Example 4 is a coating solution of water + gold (gold nanoparticles, also referred to herein as “low molecular weight gold”). Example 5 is a coating solution of water + platinum (platinum nanoparticles, also referred to herein as “low molecular platinum”). Example 6 is a coating solution of water + silk (hydrolyzed silk, also referred to herein as “low molecular silk”). Example 7 is a coating solution of water + keratin (hydrolyzed keratin, referred to herein as “low molecular weight keratin”).

  And the result of adhesion persistence is as shown in FIG. First, in the purified water of Example 1, the total remaining number of eyelash extensions after lapse of 14 days of 10 persons was 177. After 14 days, it can be confirmed that the eyelash extension has been removed. The total remaining number of Examples 2 to 7 is 281 in Example 2, 421 in Example 3, 236 in Example 4, 309 in Example 5, 354 in Example 6, and 330 in Example 7. It was.

FIG. 9 shows this in order. Expressing the rate of increase / decrease based on the purified water of Example 1, Example 1 (silver) in the first place was 237.85%, which was twice as effective. Among the sample examples 2 to 7, it was found that example 3 (silver) had the most effect of increasing the sustainability.
Second example 6 (silk) was 200.00%, which was twice as effective. It was found that there was almost the same effect as Example 1 (silver). It was found that even if it is not a metal fine particle (nanoparticle), even when an invisible protein is used, the sustainability of human hair (ground eyelashes) and eyelash extensions can be improved.
The third example 7 (keratin) was 186.44%, almost twice as effective. In Example 7 (keratin), as in Example 6 (silk), it was found that the sustainability could be increased by using an invisible protein.

The fourth-ranked example 5 (platinum) was 174.58%, and it was found that the effect of increasing the durability was weaker than that of example 3 (silver) but stronger than that of example 6 (gold).
It was found that Example 5 (Acrylates Copolymer) in the fifth position was 158.76%, which was about 1.5 times as long as lasting. Users (people) sometimes wash their face every day, and since this component (Acrylates Copolymer) is easily dissolved with soap, it was predicted that there is a high possibility of a decrease in sustainability. However, in practice, it was found that there was an effect of increasing the sustainability by about 1.5 times.
Example 6 (gold) in the sixth place was 133.33%, and the effect of increasing sustainability was the smallest among the samples, but it was still about 1.3 times the effect.

  In cyanoacrylate adhesives, it has been known that normal heptane and water, which are chemical substances, exert a primer effect. However, whether metal particles (nanoparticles) such as silver, platinum, and gold, proteins such as silk and keratin (low molecular weight proteins), and copolymers can improve adhesion persistence is an eyelash. It was not known at all in the extension industry, and in fact, it was not known what the results would be until it was confirmed by experimenting with a person with earth eyelashes (the user who lives).

  From the results of this example, it was confirmed that the adhesion persistence was improved by applying the component 40 of this embodiment. More specifically, normally, in the eyelash extension treatment method, ethanol and water containing a large amount of water are used to remove lipids and dirt attached to the eyelashes. Thereafter, the coating solution 30 containing the component 40 of the present embodiment is used. It was confirmed that the lasting power of eyelash extensions was increased by applying.

Those skilled in the eyelash extension industry (experts) should naturally use an adhesive with stronger adhesive strength instead of an eyelash extension adhesive to increase the eyelash extension's durability. It is. However, the use of a new type of adhesive rather than the conventional adhesive requires consideration of eyelid irritation, allergy problems, new skin disease problems, and effects on practitioners. And even if the manufacturer of the adhesive guarantees the quality and impact, the eyelash extension salon still hesitates to switch the adhesive.
On the other hand, according to the method of the embodiment of the present invention, it is possible to achieve the extension of the eyelash extension (extension period of the eyelash extension) using the same adhesive as before, which is very technical. Significant. In addition, there is no way to roughen the surface of the eyelash extension and thereby increase the sustainability of the eyelash extension. In this respect, too, the technical significance is very great.

  In addition, after washing the surface of the eyelash extension with ethanol or the like, in order to maintain its cleanliness, it is not possible for those skilled in the eyelash extension industry to apply something else to it. However, the method of the embodiment of the present invention dares to perform things that are contrary to the common sense of the industry, and has found that the extension of eyelash extension sustainability can be achieved. In addition, according to the method of the embodiment of the present invention, the durability of the eyelash extension can be extended simply by applying the solution 30 containing the predetermined component 40. If the surface of the eyelash extension is washed immediately with ethanol etc., the operation of wiping the ground eyelash and the operation of applying to the eyelash can be performed continuously, so the operation of the treatment can be performed smoothly, There is also an advantage that it hardly affects the work of attaching eyelash extensions (throughput).

  As mentioned above, although this invention was demonstrated by suitable embodiment, such description is not a limitation matter and of course various modifications are possible. For example, the component 40 of the coating solution 30 is not limited to a simple substance of silver (or low molecular silk), and can be used by appropriately mixing it. Two types may be mixed, or three or more types may be mixed. You may go. It is also possible to construct a coating solution 30 that is based on gold and is reinforced with silver and / or silk. Alternatively, a coating solution 30 based on silver particles (nanoparticles) may be used in a solvent composed of a mixture of water, an acrylate copolymer, and keratin. Furthermore, it is also possible to produce the coating solution 30 of the present embodiment by adding the component 40 of the present embodiment to a commercially available cosmetic liquid.

  In the example shown in FIG. 3, the eyelash extension 100 is attached to the upper eyelash 50, but the extension 100 may be attached to the lower eyelash. The artificial eyelash body 10 shown in FIG. 2 has a circular cross section, but is not limited thereto, and may be elliptical (or substantially elliptical or oval). Absent. In addition, the cross section of the artificial eyelash body 10 can be made into a polyhedron (hexagon, octagon, etc.), and the cross section can be made into a star (hexagonal star, octagonal star). Is also possible.

  Further, the eyelash extension 100 according to the embodiment of the present invention, for example, in the state shown in FIGS. 2A to 2C, using the application liquid 30 instead of the adhesive 17, the artificial eyelash body 10. It is also possible to temporarily fix the eyelash to the eyelash 50. By this temporary fixing, the user (wearer) 55 can confirm the design and the comfort of the eyelash extension 100 of the present embodiment.
