Alpha hydroxy acids (AHA) are compounds that are taken from sugars found in milk and fruits. Alpha hydroxy acids are known to be effective in rejuvenatind the skin and fading wrinkles, while healing damaged caused by photoaging skin. AHA exfoliates dead cells off the skin, encouraging the skin to grow cells to replace the old ones. AHA also induces the production of elastin and collagen, the compounds responsible for the reduction of wrinkles and the suppleness of the skin.
AHA can be found a variety of beauty products, but should be used in moderation. If used incorrectly or if you use too much, it can irritate the skin. Pigment scarring has also been associated with the use of too much AHA.
Be very careful when applying alpha hydroxy products on your skin. The best way to do it is to choose one or two products out there containing AHA (as your exfoliant and moisturizer), then use other beauty products that do not have AHA – so you don’t overdo it.
Always remember to use sunscreen when using a product with an active alpha hydroxy acid ingredient. AHA increases the skin’s sensitivity to damage from sunlight. Because too much alpha hydroxy acid can be dangerous to the skin, make sure to use a product with only the right levels of AHA in it. The ideal AHA concentration in any product should be around 5 to 8%, with a pH level of three or four. Any more can do more damage than good!
