Problems solved by technology

[0004] At present, there are many kinds of cosmetics on the market, such as facial cleanser, toner, acne lotion, acne essence, facial mask, etc. The production process and formula of these cosmetics are basically the same, and they also have different degrees of protection and beauty for human skin. effect, but the effect is not ideal, and it does not have multiple functions of anti-inflammatory, repairing, and nursing for facial acne and pimples
Moreover, after these products are applied, they will generally lose their effectiveness within a short period of time. It is difficult for the active ingredients to act on the skin for a long time to achieve the purpose of removing acne, and the efficacy is difficult to guarantee.
[0005] At the same time, the main solvent of facial cleanser, toner, acne lotion, acne essence, facial mask, etc. on the market is water, and the functional ingredients are mainly fat-soluble ingredients, which cannot form molecular dispersion in the preparation, resulting in these cosmetics. Small dosage, poor release rate, difficult release of active ingredients, transdermal absorption

Embodiment 1

[0015] Example 1: Preparation of acne patch

[0016] Preparation of cosmetic matrix: styrene-isoprene-styrene block copolymer (SIS) 1-70%, plasticizer 1-60%, tackifier 1-30%, antioxidant 0.1-3 %, 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.

[0017] Preparation of functional ingredients raw material extract: first weigh powdery 1-5% vitamin C palmitate, 0.5-2% hydrolyzed collagen, then weigh 0.05-1% lavender oil, 0.05-1% tea tree oil, 0.1% - 4% vitamin E acetate, 1-5% azone, 1-5% high-grade olive oil, etc., mix the above ingredients in a certain order, stir and mix well. Stir the prepared raw materials repeatedly for another 10-20 minutes to make them fully mixed and set aside.

[0018] Preparation method: Put the cosmetic matrix and the functional ingredient raw material extract into the quantitative sol tank and the feeding tank respectively, through the low-temperature o...
