Product description:
Kojic acid whitening active agent has better tyrosinase inhibitory effect than other whitening active agents. It does not act on other biological enzymes in the cell, and has no toxic effect on the cell. At the same time, it can enter the intercellular substance to form the intercellular glial, which plays a role in retaining water and increasing skin elasticity. It has been formulated into various cosmetics to make whitening cosmetics for freckles, age spots, pigmentation and acne.
Applied in the field of cosmetics. In human skin, tyrosine undergoes complex oxidation and polymerization with oxygen free radicals under the catalysis of tyrosinase, and finally synthesizes melanin. Kojic acid can inhibit the synthesis of tyrosinase, which can strongly inhibit the formation of melanin in the skin. It is safe and non-toxic, and does not produce sequelae of leukoplakia. Therefore, Kojic acid has been formulated into lotions, facial masks, lotions, and skin creams. It becomes a high-end whitening cosmetic that can effectively treat freckles, age spots, pigmentation, acne, etc. Kojic acid at a concentration of 20ug/ml can inhibit 70~80% of the activity of a variety of tyrosinase (or polyphenol oxidase PPO). The general addition amount in cosmetics is 0.5~2.0%.

Alpha Arbutin is a natural active substance derived from green plants. It combines "green plants, safe and reliable" and "efficient depigmentation" into a skin depigmentation combination.
Arbutin, because it was originally derived from natural green plants, is a skin whitening active substance that integrates the concepts of "green", "safe" and "efficient". There are 3 types arbutin: Alpha arbutin, Beta arbutin, Deoxyarbutin.
Glutathione is composed of glutamic acid, cysteine, and glycine. It is a tripeptide containing sulfhydryl groups. It has antioxidant and integrated detoxification effects, thereby converting harmful poisons in the body into harmless substances and excreting them. in vitro. Glutathione can also help maintain normal immune system function.
Niacinamide is a white crystalline powder; it is odorless or almost odorless and has a bitter taste. The product is easily soluble in water or ethanol, and soluble in glycerol. Melting point The melting point of this product is 128～131℃.
Malic acid can gently remove old dead skin cells and strengthen skin metabolism.
The inhibitory effect of Hydroquinone on melanin is compared with arbutin, kojic acid and vitamin C (L-ascorbic acid).The inhibitory effect of arbutin on tyrosinase is not as good as hydroquinone, but it is better than kojic acid and vitamin C.
Dipotassium glycyrrhizinate is one of the main extracts of licorice. It has antioxidant activity. It has a strong anti-radical oxidation effect in the cytochrome P450/NADPH oxidation system, and can significantly inhibit the metabolism in the body. Free radicals, to protect the biological macromolecules (LDL, DNA) sensitive to oxidation and cell walls from oxidative damage by free radicals. Its whitening effect is mainly used in cosmetics. Because of its expensive and remarkable whitening effect, it is called "whitening gold".
Tranexamic acid whitening products not only have excellent depigmentation effects, but also will not cause side effects after long-term use
