Chemical peels remove sun damage and decrease the likelyhood of skin cancer
Chemical peels remove sun damage and decrease the likelyhood of skin cancer. That is one of the main reasons for having peels. Peels do not just "exfoliate". You can do that with a rough towel. Peels actually remove damaged cells and allow new healthier skin to replace them.
Peels remove sun damaged skin but can make skin susceptible to sun damagef
Peels definitely remove sun damaged skin layers and do not directly cause sun damage, but by temporarily removing the protective upper stratum corneum layer of the skin it can make skin more susceptible to sun burning and therefore sun damage. A good sunscreen and hat for 6 weeks or longer after a peel usually helps prevent most sun damage from occurring.
The outer most layers of the skin is the most sun damaged so peels remove this outer most layers and allows healthier skin to come up and replace it. The more peels you do, the better your skin looks as a rule.
Peels stimulate the basal layer of the upper part of the skin, the epidermis, to make more cells in that area. That happens due to the fact that the epidermais has lost its top layer. The basal layer also sends signals to the second layer of the dermis so that fibroblasts make and lay new collagen in the area. regular peels get rid of sundamaged skin as the those cells are peeled off and newer more robust and freshly made ones are made.
