Skin peels after sunburn go back to normal color? how long?

Weeks to months: Depending on your skin type, it can take just a couple of weeks or up to a year for skin to return to normal color after a peeling sunburn. If you are prone to hyperpigmentation, it could be permanent. The best thing to do is avoid the sun, wear your sunscreen, and keep the skin moisturized. See your dermatologist or primary physician for a skin check yearly.
