AHA (Alpha Hydroxy Acid) Alpha Hydroxy Acids (AHAs) are a group of chemical compounds consisting of carboxylic acids replaced by a hydroxyl group on an adjacent carbon. They are commonly used in skin care cosmetics because of their mild and non-irritating properties. Currently, the most typical form of AHA in cosmetics is Glycolic Acid. Unlike BHA, AHA is a water-soluble type that is water-soluble, so it cannot penetrate deep into the pores like BHA, but only works on the surface of the skin. However, the effect of AHAs on the surface of the skin is undeniable. Therefore, AHA will be the optimal choice for those who only have problems on the surface of the skin. These include: sun and aging skin, dry, wrinkled skin, skin with pigmentation and freckles, uneven skin tone, scarred skin or rough skin.

Alpha Arbutin Arbutin is a whitening ingredient extracted from the natural bearberry fruit. Alpha Arbutin is the most potent form (having to be prepared from natural and expensive Beta Arbutin) and is considered to be the best substitute for Hydroquinone to date.
