ALPHA HYDROXY ACIDS

TYPE OF INGREDIENT: Acid/chemical exfoliant MAIN BENEFITS: Exfoliate the top layers of skin to minimize dullness and even out texture; some AHAs can also stimulate collagen production, while others have antioxidant and hydrating properties. WHO SHOULD USE IT: Given their wide range of effects, most people can benefit from using AHAs, so long as you find the right alpha hydroxy acid and concentration of it for your particular skin type.

HOW OFTEN CAN YOU USE IT: This differs greatly based on the particular acid, product, and skin. Follow product directions, but always start slow, using any AHA only once or twice per week and gradually increasing frequency as your skin can tolerate it.

WORKS WELL WITH: Peptides can slow the penetration of AHAs, making them less irritating. You can also pair them with hydrating ingredients.

DON'T USE WITH: Avoid using retinoids at the same time of day as AHAs, and be cautious when using both BHAs (beta hydroxy acids, such as salicylic acid) and AHAs in order to minimize irritation.
