Hydroxy Acids

Hydroxy acids are products used to exfoliate the skin. They are classified by their chemical structure as either alpha-hydroxy acids or beta-hydroxy acids. Alpha hydroxy acids are typically derived from plant sugars and include glycolic acid, lactic acid, citric acid, mandelic acid, malic acid, and tartaric acid. The most common beta hydroxy acid is salicylic acid, which is found in many acne products. Beta hydroxy acids are stronger than alpha hydroxy acids and thus lower concentrations are used.

As we age, dead skin cells accumulate on the surface. This is because skin cell turnover slows down over time. The effect of this is uneven texture and overall dullness to the skin. Hydroxy acids remove the dead skin cells on the surface by breaking the bonds holding them together, resulting in a brighter glow and radiance. They also act in the deeper layer of the skin to stimulate collagen formation improving fine lines and reducing pore size and laxity.

With all of these beneficial effects, hydroxy acids can be used in any skin care regimen. Other components of a good skin care regimen include face wash, toner, antioxidants, retinoids, hydrators, moisturizers, and sunscreen.
