First of all, the full meaning of AHA is Alpha Hydroxy Acid, while BHA simply stands for Beta Hydroxy Acid. The two are used on skins to remove dead cells so that the living cells can appear on the body. There are five different types of AHAs that can be used for skin exfoliation, which are glycolic, citric, tartaric, malic, and lactic acids.
The only kind of BHA that is used is salicylic acid. The main difference that makes AHA be different from BHA is their solubility. AHAs do not penetrate so deep into the skin, and they are soluble in water. The BHA, on the other hand, penetrates deep into the skin, and it is soluble in oil. The AHAs are more effective when used to remove dead skin cells that are caused by sun damage. Conversely, the BHA is more effective in clearing clogged pores, going deep into the skin so that they can be eradicated.
BHA and AHA mean different things. When you say BHA, this means beta-hydroxy acid. When you say AHA, this means Alpha Hydroxy Acids. It is obvious that these are two of the ingredients that you would normally see when you look at the skincare products that you normally use.
AHA is more recommended if you would like to make sure that you would get rid of some of your acne scars and some of your skin concerns. BHA is more recommended if you are searching for products that will work best for those who have oily skin. There are some products that will have both these ingredients while those who have combination skin may want to use alternating products.
