Our expert says:
There are two types of hydroxy acids - alpha and beta. Alpha hydroxy acids are exfoliants derived from fruit and milk sugars such as glycolic acid produced from sugar cane and lactic acid produced from milk. There is only one beta hydroxy acid - salicylic acid. Both of these are effective in the treatment of your condition.
Beta hydroxy acid works mainly as an exfoliant. It causes the cells of the epidermis to become "unglued" allowing the dead skin cells to slough off, making room for regrowth of new skin.
Ask your pharmacy which products they keep containing glycolic, lactic or salicylic acid. I'd rather recommend using a medicated cream containing urea twice a day - Nutraplus would be a good idea.
