Skin color is mainly determined by melanin, and the production of melanin is affected by many factors. If people with dark skin want to whiten their skin, they need to start from three aspects: inhibiting melanin production, accelerating melanin metabolism and preventing ultraviolet stimulation.
1.Melanin production mechanism:Tyrosinase activity is key to melanin synthesis, and inhibiting its activity can reduce melanin production.
2.Melanin metabolism process:The skin metabolism cycle is about 28 days, which promotes the renewal of the stratum corneum and helps lighten existing melanin.
3.UV protection:UV radiation stimulates the activity of melanocytes, so sun protection is the basic step for whitening.
