The real name, or a common alternative name, for glycolic acid is hydroxyacetic acid.
Glycolic acid, known scientifically as hydroxyacetic acid, is a simple alpha-hydroxy acid (AHA). As noted in the provided reference:
Glycolic acid (or hydroxyacetic acid; chemical formula HOCH2CO2H) is a colorless, odorless and hygroscopic crystalline solid, highly soluble in water.
This indicates that "hydroxyacetic acid" is synonymous with "glycolic acid." It is the smallest molecule in the AHA family, which is why it can easily penetrate the skin.
