Glycolic acid is alpha hydroxyl acid. It belongs to group of organic carboxylic compounds and is derived from sugar cane. It is one of the most common agents to be used for chemical peeling. Glycolic acid has a keratolytic, germinative layer and a fibroblast stimulating action. It also has anti-inflammatory effects and anti-oxidant action. It acts by thinning the stratum corneum, promoting epidermolysis, dispersing basal layer melanin and stimulates epidermal and dermal hyaluronic acid and collagen gene expression that increases through an elevated secretion of IL-6. Glycolic acid is an important adjunctive therapy in a variety of conditions including photodamage, acne, rosacea, striae albae, pseudofolliculitis barbae, hyperpigmentation disorders, actinic keratoses, fine wrinkles, lentigines, melasma and seborrheic keratoses. Glycolic acid chemical peels are an effective treatment for all types of acne, inducing rapid improvement and restoration of normal-looking skin. Glycolic acid peel is very safe with minimal adverse effects. It has a short post operative period, causes very mild erythema and desquamation.
