Glycolic acid works as an effective peeling agent at concentrations ranging from 20-70%, treating skin texture issues and surface damage across most skin types and body areas. Results show it creates similar improvements to stronger TCA peels in deeper skin layers, though TCA caused more surface damage; however, skin returned to its pre-peel appearance within 2 years, meaning results aren't permanent.
This was a review of glycolic acid's use as a chemical peel, examining how different concentrations affect various skin conditions and comparing the results to other peeling methods like TCA.
