Luxurious benefits of Lactic Acid by Dr. Philip Young of Bellevue: Lactic acid is an alpha hydroxy acid naturally found in milk and sugars. It breaks down bonds (called demosomes) between cells to allow for easier exfoliation of dead surface cells and hydrates the skin. Just like glycolic acid, another popular AHA, lactic acid is very effective in reducing fine lines, wrinkles, age spots and hyperpigmentation. Here at Aesthetic Facial Plastic Surgery, we have two different strengths of lactic acid peels which combine the benefits of TCA (Trichloroacetic Acid, another acid commonly used in peels) and other key ingredients like Vitaminc C, Kojic Acid, Azelaic Acid and more! The Sensi Peel has 12% Lactic acid and the Ultra Peel 1 which has 20% Lactic acid. For more information regarding our peels:
