A: No, tattoo ink is injected into the epidermis and dermis, which are deeper layers of skin. Chemical peels can’t be applied safely to reach these levels, writes Dr. Zelickson. He suggests laser removal for tattoos instead.

A: Peels should be administered by a licensed professional: a dermatologist, nurse, plastic surgeon or esthetician (though estheticians can’t perform deeper peels). At-home peels are also available, though professional peels will provide more dramatic results. For dull skin, try a weekly peel with “glycolic, lactic, citric and malic acids…or salicylic acid,” suggests dermatologist Doris J. Day, M.D., in Allure. Try MD Skincare Alpha Beta Daily Face Peel/2 Steps to reduce the look of lines and even out skin tone. At-home peels also help other skincare products penetrate better by removing dead skin, which can act as a barrier.

A: It depends on the peel’s strength. Mild or medium peels may require repeat treatments every few months to achieve the best results. However, “in general, a person cannot have repeated deep phenol peels,” warns Essig.

A. The tattoo and surrounding skin should be completely healed before shaving. You’ll know the area has healed when there’s no peeling or irregularities (including bumps, scabs or raised areas). For most people, complete healing takes five to 10 days.
