As one of the derivatives of L-cysteine, it is more direct in use and has a wide range of applications in the pharmaceutical and cosmetic industries.
In cosmetics: N-acetyl-L-cysteine can remove oxygen free radicals and other oxides, and slow down the aging, the mechanism is not completely clear, may be related to the synthesis of glutamate. With the development of fine cosmetics, recent photomedicine and photobiology studies have shown that n-acetyl-L-cysteine can reduce the melanin in the epidermis and eliminate the melanin that has been deposited. Therefore, n-acetyl-L-cysteine has been increasingly paid attention to as a whitening cosmetic.
