What is Alpha Hydroxy Acid?
Alpha hydroxy acids help the skin by rejuvenating it. They include citric acid, which is found in fruits, glycolic acid, which is found in sugar cane, malic acid, found in apples, tartaric acid, found in grapes, and lactic acid, which is found in sour milk. There are other types of alpha hydroxy acids as well and all will be found in foods. They can be applied to the skin topically to moisturise and remove dead skin cells, and are wonderful for treating acne and removing acne scars. They can be used for improving the appearance of photo-aged skin, and work well to firm and smooth skin. Alpha hydroxy acids are often added to lotions and creams to help relieve dry skin. Alpha hydroxy acids are used in chemical peels in different concentrations, usually ranging from 10% to 70%. A dermatologist will be able to apply products to the face that contain alpha hydroxy acids, in concentrations from 50 % to 70%. These treatments are perfect for erasing lines and wrinkles and will generally last about 2 to 5 years. Products with alpha hydroxy are sold over the counter in concentrations of 10% or less.
