Acne is a chronic inflammatory disease of the sebaceous hair follicles. Every follicle contains a tiny hair and multiple sebaceous glands. With normal circumstances, sebum, the oily substance made by the sebaceous glands, travels up the hair follicle and out to the skin's surface. However, with acne, sebum is trapped within the follicle and skin bacteria multiplies within the clogged pores. Acne usually develops on those areas (the face, scalp, neck, chest, upper arms, back, and shoulders) of the skin where the sebaceous glands are most numerous.
Glycolic acid peel is one of the most common peels used to treat acne. Glycolic acid is an alpha hydroxy acid, which when used in combination with oral or topical medications, can hasten the response of acne to treatment by reducing the amount of sebum being trapped in the follicles. Glycolic acid peels exfoliate dead layers of the skin.
Salicylic acid peels are also used to treat acne. Salicylic acid is a beta hydroxy acid that is oil soluble and can penetrate oil plugged pores. A Salicylic acid peel can be repeated every two to four weeks.
