A chemical peel is solution applied to the face to remove dead skin cells and stimulate the growth of new cells.The aim is to improve the appearance of the skin – for example, by reducing age spots and evening out skin tone. The acid removes a uniform amount of damaged skin cells across the treatment area. When done appropriately, this allows the skin to heal, with minimal scarring or color changes.Chemical peels can affect two layers of the skin, the epidermis and the dermis. The epidermis is the visible outer layer, and the dermis sits just beneath. This deeper layer contains nerve endings, sweat glands, and hair follicles.
