Function of Decapeptide-12
Decapeptide-12 is a cosmetic raw material that inhibits the formation of melanin, diminishes pigmentation, reduces pigmentation, and even and brightens the skin tone. It was developed by researchers from the Department of Dermatology at Stanford University. It is currently the only one that has been proven to effectively inhibit the skin A novel peptide with tyrosinase activity.
Decapeptide-12 can inhibit the synthesis of tyrosinase, thereby effectively (40%) reducing the production of melanin. It can minimize chloasma, freckles, age spots, sunburn, uneven skin tone and light damage caused by over-pigmentation. And decapeptide-12 does not have the toxicity and side effects of other whitening ingredients such as hydroquinone, such as allergies, irritation and redness.
