Not dissimilar to chemical peels, laser resurfacing treatments help exfoliate the top layer of your skin on an extreme level to stimulate new collagen production. "The laser version of a chemical peel — such as Fraxel — uses laser light to penetrate deeply and create wounds in the skin," Dr. Gmyrek said. While the skin is healing from this sort of treatment, it is incredibly sensitive to the sun. "If you get unintended sun exposure during this time, it will likely compromise your results and also put you at risk for healing with extra and possibly irregular pigmentation on the skin."
