[0030] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

[0031] The embodiments shown below are devices and methods exemplified to embody the technical concept of the invention, and the technical concept of the invention is not limited to the following contents. The technical concept of the invention can be modified in various ways within the scope of the matters recorded in the scope of the patent claims. In particular, it should be noted that the drawings are schematic and may differ from the actual situation. The description of the known technical part is omitted.

[0032] Hereinafter, a device for increasing the collagen density in the dermis layer and a skin treatment method for increasing the collagen density in the dermis layer will be described.

[0033] The skin treatment device 1 is configured to be used on the user's skin to which any collagen-generating substance containing dipeptides and tripeptides is applied (coated), and can apply alternating current stimulation of 1.5 kHz or less to the user's skin. The method of applying the collagen-generating substance to the user's skin is arbitrary, and can be direct application or a method of contacting a cotton sheet or sheet containing the collagen-generating substance with the user's skin. The following mainly describes "application", but other methods of application instead of application can also be used.

[0034] The skin treatment device 1 can apply alternating current stimulation of 1.5 kHz or less to the skin of the user to which any collagen producing substance including dipeptides and tripeptides has been applied through the collagen producing substance.

[0035] A cosmetic method for applying alternating current stimulation of 1.5 kHz or less to a target part of a user to which any collagen-producing substance including a dipeptide and a tripeptide has been applied.

[0036] A treatment method for applying alternating current stimulation of 1.5 kHz or less to a target area of ​​a user to which any collagen-producing substance including a dipeptide and a tripeptide has been administered.

[0037] Skin treatment devices 1 include various types such as mask type and portable type that users can hold in their hands. Figure 1 and Figure 2 In the example of the skin treatment device 1, the conductive material has the first and second sheet electrodes 2a and 2b. The first and second sheet electrodes 2a and 2b are independent and can be attached to the desired parts of the skin 7 by the user. The first and second sheet electrodes 2a and 2b are electrically connected to the current generating part 4 through the wire 3. Figure 1 and Figure 2In the example shown, the wire 3 is divided into two branches, the first and second branch wires 3a, 3b. The first and second branch wires 3a, 3b are connected to the first and second sheet electrodes 2a, 2b respectively. The other end of the wire 3 has a universal jack or plug for connecting to the current generating unit 4. The current generating unit 4 applies an alternating current stimulation of 1.5kHz or less to the target part of the user.

[0038] The conductive material can be made of flexible conductive polymers, carbon black, resin, dielectric elastomer actuator (DEA), IPMC actuator, PVC gel, etc., so that it can follow the uneven surface of the skin. In addition, the conductive material can be thin so that it can be attached to the user's skin and transparent and inconspicuous, or it can be in a form that matches the user's skin color. The conductive material can be reusable or disposable, and cosmetics or sunscreen can be used on it.

[0039] The conductive material itself may be sticky or may be provided with an adhesive layer so that a pulse wave having the frequency of the present invention can be applied to the skin. In addition, the conductive material can be installed on the skin by providing an adhesive layer on the device part or providing a mounting component such as a belt on the device, or by the stickiness of the sheet electrode. A drug layer may be arranged between the conductive layer and the adhesive layer. Alternatively, in addition to the conductive layer and the adhesive layer, a microneedle layer having microneedles made of hyaluronic acid or the like may be included. The microneedle layer may be arranged on the side of the adhesive layer opposite to the conductive layer, i.e., the side in contact with the user's skin.

[0040] The adhesive layer used for the electrode can be any material as long as it has a holding force when adhered to the skin and does not cause pain when torn off, and can be provided on a surface of the support material by coating, impregnation, bonding or casting. Preferred examples of the adhesive component include various water-soluble polymers, oil-soluble polymers or gelling agents partially modified by cross-linking or other methods. The type, ingredients and ingredients conditions of the cross-linking agent can be selected from known methods.

[0041] Figure 3 It is a bar graph showing the effectiveness of the combined use of collagen application and AC electrical stimulation of a beauty device.

[0042] exist Figure 3 The test results of the forehead, eye corners, etc. are shown in the figure. The three bar graphs of each part represent the test results before use, after 4 weeks, and after 8 weeks. The vertical axis represents the collagen density (intensity). In addition, the application of collagen is synonymous with the application of cosmetics containing collagen. Figure 3 There is a table below the bar graph, which shows the rate of change of collagen density with the value before use as 100%.

[0043] Figure 3The comparison results of the collagen density after 4 weeks and 8 weeks between the application of collagen (with a beauty device) and the application of collagen alone are shown. It was found that the use of a beauty device can increase the collagen density.

[0044] Figure 4 The test results are shown. Figure 4 The test results show whether there is a significant difference (significant difference) in the collagen density of the dermis when collagen application and beauty device are used in combination (C40) and when collagen is applied alone (C42). Figure 4 In the case of using collagen application and facial beauty device at the same time, the left side shows before application and the right side shows after application in the two photos shown in C40. This also applies to the case of applying only collagen (C42).

[0045] like Figure 4 As shown, when high molecular substances such as collagen are used in combination with beauty devices, the penetration effect is better and the collagen density in the dermis is improved.

[0046] Figure 5 Other test results are shown.

[0047] exist Figure 5 In the figure, curve G51 represents the control group (no special operation such as cosmetic application or device use was performed during the test), and the other curves are as follows:

[0048] Curve G52: Collagen only

[0049] Curve G53: Applying only the base without collagen-forming substances and applying 1kHz AC stimulation

[0050] Curve G54: Collagen application and 1kHz AC stimulation

[0051] like Figure 5 As shown, applying alternating current stimulation to active ingredients such as collagen-producing substances can promote the increase of collagen density, and this effect depends on the frequency of the alternating current stimulation.

[0052] based on Figure 5 Based on the results, the inventors conducted further additional tests (experiments) to find the appropriate frequency range of AC stimulation for use in combination with collagen application, and obtained the following test results.

[0053] Figure 6 Further other test results are shown.

[0054] like Figure 6As shown in the results, applying 1kHz, 10Hz alternating current stimulation to the active ingredients containing collagen-generating substances can promote the increase of collagen density more than simply applying collagen. Figure 6 In the figure, each curve is represented as follows:

[0055] Curve G61: Collagen only applied without stimulation

[0056] Curve G62: Collagen application and 1kHz AC stimulation

[0057] Curve G63: Applying collagen and applying 10-50 Hz AC stimulation

[0058] from Figure 6 It can be seen that the applied AC stimulation frequency is effective in the range centered at 1 kHz and in the range of 10 to 50 Hz.

[0059] Here, Figure 7 The test results using the same collagen as above are shown. It can be seen that there is no significant effect when the frequency exceeds 1.5kHz, such as 2kHz, but the effect is better between 1Hz and 9Hz.

[0060] Figure 7 Further other test results are shown. It is worth noting that Figure 7 The test in is with Figure 6 The study was conducted on subjects of different genders. Figure 7 In the test, the following four test results were compared within 4 weeks (marked as "4w" in the figure):

[0061] Curve G71: Collagen only applied without stimulation

[0062] Curve G72: Applying collagen and applying ultra-low frequency alternating current stimulation of 1Hz to 9Hz

[0063] Curve G73: Apply collagen and apply 2kHz medium frequency AC stimulation (with body sensation)

[0064] from Figure 7 It can be seen from the figure that, for the frequency of the applied AC stimulation, the ultra-low frequency of 1 Hz to 9 Hz is more effective than 2 kHz. Figure 6 and Figure 7 It can be seen from the test that for the frequency of the applied AC stimulation, applying a medium frequency range centered at 1kHz and a low frequency of 10 to 50Hz is more effective than an ultra-low frequency of 1Hz to 9Hz.

[0065] Figure 8 Further other test results are shown.

[0066] Figure 8 is with Figure 7 The test was conducted on subjects of the same sex. Figure 8 In the test, the following four test results were compared within 4 weeks (marked as "4w" in the figure):

[0067] Curve G81: Collagen only applied without stimulation

[0068] Curve G82: Collagen was applied and 0.5kHz medium frequency AC stimulation was applied

[0069] Curve G83: Collagen was applied and 1kHz medium frequency AC stimulation was applied

[0070] Curve G84: Collagen was applied and 1.5kHz medium frequency AC stimulation was applied

[0071] from Figure 8 It can be seen that the collagen density at 0.5kHz has a tendency to improve, but it is not as obvious as the effect of 1kHz and 1.5kHz. In addition, there is no significant difference between 1kHz and 1.5kHz, and the effect is good.

[0072] As mentioned above, from Figure 6 , Figure 7 and Figure 8 It can be seen that the applied AC stimulation frequency is more advantageous in the mid-frequency range centered at 1kHz to 1.5kHz and the low-frequency range of 10 to 50Hz.

[0073] Reference Fig. 9 . Fig. 9 refer to Figure 6 The test method for the above test is shown. It should be noted that Figure 7 The test methods shown in are substantially the same, with only the frequency of the AC stimulation being different. The details of the test method are arbitrary and may be changed as appropriate. Figure 3 and Figure 4 The test conditions are shown in Fig. 9A middle.

[0074] Fig. 9 The test shown was performed using the following method:

[0075] Beauty instrument for testing

[0076] Waveform name / Usage time / Usage level Lv: 1kHz medium frequency, 10Hz to 50Hz low frequency / 10 minutes per test site / Lv3 (maximum level Lv).

[0077] Cosmetics / Dosage: Collagen derived from fish diluted with an aqueous solution containing thickening and energizing ingredients Aqueous solution containing only thickening and energizing ingredients (including moisturizing ingredients such as glycerin) / 1.0 ml per test site 5 cm×5 cm area

[0078] Measurement item (measuring instrument): Intensity (DermaLab ultrasonic dermal imaging device).

[0079] Directions: Clean the test area with facial cleanser. Divide the test area into three areas on the inner side of the forearm, and six areas on both arms according to the different positions of the subjects, and use the instrument according to the predetermined test order. Control area... No special operation (such as cosmetics application or instrument use, etc.) is performed during the test. Cosmetic area only... Apply a specified amount of cosmetics and let it stand for 10 minutes, wipe it gently with a tissue, and pat it until absorbed. Instrument area... Apply a specified amount of cosmetics and continue to move the instrument at a speed of 1 circle per second. After 10 minutes, wipe it gently with a tissue and pat it until absorbed (gently spread it evenly).

[0080] Measurement method: After washing with facial cleanser, let it stand for 10 minutes to adapt. The intensity is 9 points, the stratum corneum moisture is 3-5 points, and the skin elasticity is 2-4 points. Then, the stratum corneum moisture, skin elasticity and strength are averaged.

[0081] The above detailed description of each embodiment does not limit the invention to a specific embodiment, and various modifications and variations are possible within the scope of the claims. In addition, all or part of the constituent elements of the above embodiments may be combined.

[0082] In addition, the implementation method is not limited to a sheet electrode with an adhesive layer. Any collagen-generating substance including collagen, dipeptides and tripeptides can be applied to the skin, and then AC stimulation can be performed using a beauty device having at least a pair of electrodes, or a mask or cotton sheet soaked in any collagen-generating substance including collagen, dipeptides and tripeptides can be attached tightly to the skin, and then a sheet electrode or a mask-type electrical instrument that can apply current can be used from above.

[0083] Alternatively, conductive ink may be printed on a sheet such as a nonwoven fabric that can retain moisture, and after any collagen-generating substance is impregnated into the sheet, current may be applied to the sheet, and the current may be applied to the skin through the conductive ink.

[0084] Any collagen-forming substance including dipeptides and tripeptides may be of animal or fish origin, and may have an average molecular weight of 1,000 to 10,000. It is also advisable to use collagen having an average molecular weight of 1,000 or less. For example, as shown below.

[0085] <A peptide having 2 to 8 repeating peptide bonds or a derivative thereof, which is water-soluble>

[0086] As cosmetic raw materials, useful peptides are those with 2 to 8 amino acid repetitions, and these peptides are ideal. These peptides also include oligopeptides containing these peptides. When limiting the types of amino acids, glycine, alanine, proline and hydroxyproline, histidine, threonine, and arginine are ideal. The effects of useful cosmetic peptides include anti-wrinkle, collagen production, skin anti-aging, and skin cell activation. Specific examples of compounds are as follows Fig.10 The name shown.
