Chemical peels improve the cell turnover of the epidermis, which reduces the efficacy of melanin spread into the epidermis, hence the skin starts to appear lighter in colour.
There are various types of peels that are helpful in pigmentation, like AHA, BHA, phenol, retinol, TCA, Mandelic acid, Vitamin C, Acetic acid, etc.
The peel partially or completely removes the superficial layer of skin and stimulates the regeneration of new cells, which will have less pigmentation than before. Chemical peels should be performed every 4-6 weeks and then maintained every 2-3 months. Most chemical peels are very safe and satisfactory.
Strict sun protection and sunscreen application are needed after chemical peels. Prior to a chemical peel, your skin might need priming with tretinoin or glycolic acid so that you can get the most out of your session.
A chemical peel is a 15-to-30-minute procedure that can be done at any time of the day. After a chemical peel, you can immediately resume your daily activities except the ones that require you to be outdoors or in the pool.
