Glycolic acid is a type of alpha-hydroxy acid, or AHA, that can be an effective staple of any skin care regimen. A glycolic acid molecule is extremely small, enabling it to penetrate the skin more easily and deliver powerful results. While glycolic acid is often administered as a peel, using a glycolic acid cream can deliver greater benefit, since it is left on to be absorbed by the skin.

Glycolic cream--also known as glycolic acid cream--is a skin product produced from glycolic acid, a naturally occurring alpha hydroxy acid that is derived from cane sugar, unripe grapes and sugar beets. Glycolic acid is the main active ingredient in formulations such as glycolic creams, which offer a number of cosmetic and medicinal benefits.
