In previous articles we discussed the biology of the skin layers (or epidermis) and the acid mantle. We learned the acid mantle is a very important part to skin health. It is what protects our topmost layer of skin from infection and intrusion of harmful bacteria. Now we discuss the more popular skincare acids in detail and how they are used.

Who would want to put acid on their face?

If you follow trends in skincare and skin products, you most likely have seen numerous references to ‘acids’ – names like, Alpha Hydroxy Acid, Glycolic Acid or Ascorbic Acid to name a few. While the term “acid” may seem harmful or irritating, when used in the proper products and in controlled amounts, it can actually heal and rejuvenate skin – much the same way the acid mantle protects it. The trick in proper skincare is to find the right balance between acid and alkaline maintenance of the skin.

You may not know exactly what these acids do for your skin and how they might help you. Understanding skincare ingredients is key to selecting the right products for your unique skin type and skin concerns.
