Glycolic acid has the smallest molecular weight and is easily able to penetrate the skin. It is a weak acid. It has a keratolytic action. With higher ph it acts as a moisturizer. Since it is a weak acid it does not have a self neutralizing action by coagulation of proteins hence it has to be neutralized with water or weak buffer.

Glycolic acid result in superficial skin injury and are well tolerated - the 'lunchtime' peel. They remove thin lesions on the skin surface, reducing pigment and surface dryness.

Glycolic peels of 50% and 70% concentration can be used on the face without getting irritation and burning. These peels are applied with a pre-peel cleanser containing strontium nitrate. It directly acts on the type c- nerve depolarization that transmits itching, stinging & burning sensations.
