Problems solved by technology

At present, the whitening chemicals used in cosmetics at home and abroad are mainly hydroquinone, kojic acid, fruit acid, arbutin and vitamin C derivatives, etc. Hydroquinone and mercury salts can achieve rapid whitening effects, but their toxic side effects are large, and long-term use will cause Causes permanent skin depigmentation and contact dermatitis
Long-term use of kojic acid has cytotoxicity and can increase the incidence of chromosome exchange and chromosomal aberration in ovarian cells. However, kojic acid derivatives have stronger whitening effects and less toxic side effects. Most of the current whitening cosmetics use this as an active ingredient ;Arbutin has a mild effect, but excessive dosage has similar toxic and side effects to kojic acid
Vitamin C derivatives have disadvantages such as poor stability and high price
