Alpha Hydroxy Acids

Alpha Hydroxy Acids

Alpha hydroxy acid products in concentrations of 4% to 10% are not effective for inhibiting melanin production and won"t lighten skin discolorations. However, there is evidence that in combination with other treatments such as kojic acid, hydroquinone, azelaic acid, and laser resurfacing they can be very effective for improving the overall appearance of sun-damaged skin and possibly helping the other ingredients penetrate the skin better. Much like laser treatments, alpha hydroxy acid peels (using 50% concentrations) have impressive results for removing skin discolorations.

Only a physician should perform these types of facial peels.
