Chemical peels are cosmetic treatments used to improve the appearance of the skin. They involve applying a chemical solution to the skin, which causes the top layers to exfoliate and eventually peel off. This process reveals new, regenerated skin that is typically smoother and less wrinkled than the old skin. Chemical peels can be used to treat various skin issues such as acne scars, sun damage, fine lines, and uneven skin tone. There are different types of peels, ranging from superficial to deep, depending on the intensity and the specific needs of the patient's skin.
