To understand how Vitamin C work for skin whitening, here are a few basic things you should know about skin pigmentation:
- Skin color comes from a pigment called melanin. This pigment is made by melanocytes, a type of cell deep within the skin.
- Melanocytes convert an amino acid called tyrosine into melanin. It uses an enzyme called tyrosinase to do this.
- These pigments are then transported to the upper layers of the skin where they are deposited.
- The more melanin is produced, the darker your skin gets.
- Melanin comes in two forms. It can be a lighter, yellowish Pheomelanin or a darker brown Eumelanin.
- Many things can increase the activity of melanocytes.Sun exposure, estrogen imbalance, some medications and post inflammatory hyperpigmentation all increase the production of melanin.
- UV radiation, smoke and pollution produce free radicals that damage the skin and increase pigmentation.
