Question: what is the difference between lactic acid and glycolic acid peel?
Answer: Glycolic Acid is the most active and beneficial of the Alpha-Hydroxy-Acids (AHA) in skin care and is made from sugar canes. ... The Lactic acid is less irritating and more moisturizing than the Glycolic, and the Lactic can be used at a slightly higher concentration than the Glycolic, because it is not as irritating.
