Introduction

Procystein is a newly developed light whitening substance. Related reports have confirmed that leucothiamine has strong antioxidant and detoxification functions, and has the effect of inhibiting tyrosinase activity. As a cosmetic, it can not only whiten, moisten, protect, sterilize and protect skin from ultraviolet radiation; At the same time, it can promote the biosynthesis of glutathione in subcutaneous cells, improve the ability of quenching oxidative free radicals in subcutaneous cells, so as to enhance the protective layer of natural antioxidant system in subcutaneous cells. It can improve skin symptoms such as skin aging, crispness, atrophy, exfoliation, discoloration, sagging, acne, itching, eczema, skin warts, wrinkles, orbital lines, eye bags, etc., and is conducive to the recovery of skin vitality, Improve skin flexibility, texture, luster and anti ultraviolet radiation. Its effect is nearly 20 times of that of ursolic acid, a popular light color whitening ingredient

Application

1. Inhibition of tyrosinase activity

Tyrosinase is a kind of polyphenol oxidase containing copper, which is the key enzyme of melanin synthesis. Inhibition of its activity can inhibit the formation of melanin, and then achieve the effect of improving skin color and whitening.

2. Remove oxygen free radicals

Reduce the negative effects of exogenous factors such as ultraviolet, oxygen free radicals on the physiological process of melanin formation, so as to protect the skin, slow down aging and eliminate wrinkles.

3. Soften cuticle and whiten skin

It can soften stratum corneum, activate cell regeneration, whiten skin and accelerate the stratification of keratinocytes

4. Reduce the pigmentation of synthesized melanin

It has the function of antioxidation and free radical scavenging, delaying skin aging, inhibiting the formation of pigment deposition through the oxidation pathway of newly synthesized melanin.
