Problems solved by technology

Especially for skin inflammation, pigmentation, chloasma and other skin care cosmetics, there are quite a lot of skin care cosmetics, and most of these skin care cosmetics are composed of emulsion or cream synthesized by chemical additives. It also damages the healthy skin and accelerates the aging of the skin
At the same time, there are a few water-soluble patch treatments for freckle patches, but the effect is not obvious

Embodiment 1

[0017] Preparation of speckle-removing patch: the preparation process adopts the method of preparing the raw liquid medicine and the base material separately.

[0018] Preparation of raw material liquid medicine: first weigh 0.1-1% cooling agent and grind it into fine powder, take 1-5% aloe vera oil, 0.5-2% green tea oil, 0.5-5% vitamin C derivatives, 0.5-2% licorice extract, 1-10% azone, 1-10% high-grade olive oil, etc., the above solution is stirred and mixed. Stir the prepared raw material medicine solution repeatedly for another 10-20 minutes, and set aside.

[0019] Preparation of matrix material: styrene-isoprene-styrene block copolymer (SIS) 1-75%, plasticizer 1-65%, tackifier 1-35%, antioxidant 0.1-3.5 %, react at a high temperature of 100-200°C for 0-5 hours to make a matrix material suitable for human skin. After cooling the glue block, set aside.

[0020] Preparation method: Put the raw drug solution and matrix material into the quantitative drug administration t...

Embodiment 2

[0021] Example 2: Biomechanical determination of freckle-removing patch

[0022] The samples produced in Example 1 were subjected to biomechanical measurements to determine the requirements for adapting to the facial skin of the human body, especially the initial adhesion, holding power and peeling force requirements of the delicate skin of the face. The results are shown in Table 1.

Embodiment 3

[0026] The freckle-removing patch prepared by the method of embodiment 1 is done following clinical test:

[0027] The age of the test population:

[0028] Fifty middle-aged women aged 28-45 who were troubled by scars met the inclusion criteria.

[0029] Instructions:

[0030] Remove the package, take it out, remove the protective layer, and gently stick the patch on the designated spot of the tester. Do not press with your fingers, otherwise it will affect the curative effect.

[0031] The use time is two months, divided into two courses of treatment, each course of treatment is one month. Course 1: Twice a day, once in the middle of the day and once in the evening after cleansing, for 45 minutes each time. Course of treatment 2: Once a day, use after cleansing the skin every night for 45 minutes. Observe and record the test phenomena.

[0032] Observation index: naked eye observation

[0033] Before and after each use of the freckle patch, take pictures to record the ...

Abstract

The invention discloses a spot removing patch made of a novel substrate material, and a preparation method thereof. The spot removing patch is mainly added with the following components: aloe oil, green tea oil, a vitamin C derivative and a liquorice extract. An adhesive prepared by combining a novel elastomer material of styrene-isoprene-styrene triblock copolymer (SIS), a thickening agent and a plasticizer is taken as a cosmetic substrate material. A preparation process for a novel external patch is a low-temperature online fusion molding technology. The spot removing patch prepared by the method can obviously improve facial blackspots, has the multiple effects of removing spots, whitening and moisturizing, can infiltrate skin surface and fade various blackspots, and fulfills the aim of removing newly generated blackspots.

Description

technical field [0001] The invention relates to a freckle removing patch using a novel elastomer material-styrene-isoprene-styrene block copolymer (SIS) matrix material and a preparation method thereof, belonging to the field of skin care products. Background technique [0002] The main types of spots are as follows: [0003] Melasma, also known as liver spots, is mostly distributed on the forehead, cheeks, nose, etc., presenting irregular patches, but symmetrically distributed. Most of the causes of chloasma are related to endocrine, while sun exposure and mental stress will aggravate the color of chloasma, showing large areas of light yellow spots. [0004] Dark spots, also known as butterfly spots, are mostly concentrated on the cheeks and look like a butterfly. There are multiple factors that can cause dark spots. Long-term excessive ultraviolet radiation, aging and inflammation of the skin, or long-term acne and eczema will stimulate the reproduction of black cells a...
