Chemical peels are a popular cosmetic procedure used to improve the appearance of the skin. They involve applying a chemical solution to the skin that causes the outer layer of the skin to peel off, revealing a smoother, more even-toned layer underneath. Chemical peels can help improve the appearance of fine lines and wrinkles, sun damage, acne scars, and uneven pigmentation. They can be performed at varying depths, from superficial to deep, depending on the specific needs of the patient.
