You may have been seeing AHA and BHA products everywhere in skin care lately, as many K-beauty brands and Sephora fave Drunk Elephant have incorporated these superpowered, complexion-improving ingredients in their products. If you are stumped on what the heck AHA and BHA ingredients actually do for your skin, we caught up with Drunk Elephant’s Director of Education Nathan Rivas to help set the record straight.

Although AHA and BHA ingredients usually go hand-in-hand, Rivas says that AHA acids or alpha hydroxy acids are usually lactic, citric, and glycolic acids, which are derived from vegan and non-vegan sources. These sorts of acids function as leave-on exfoliants, which work to gradually dissolve the bonds holding dead skin cells together. Additionally, he says, these acids are very helpful in improving skin texture and tone, and reducing the appearance of fine lines and wrinkles.

If you are interested in adding AHA into your beauty routine, Rivas recommends using AHA products at 8% and 15%. However, he warns that glycolic acid (the most common AHA) at 10% is already strong enough, so you’ll want to be cautious with how much you actually apply to your face. Rivas also notes that unlike BHA ingredients, alpha hydroxy acids aren’t as effective at unclogging your pores.

In contrast, BHA or beta hydroxy acid goes a little further than AHA.

Rivas says these acids gradually exfoliate the skin, while also working to penetrate and exfoliate deep into your pores, too. Because these acids tend to go a little deeper than AHAs, BHA acids help your products (think serums and creams) absorb better.

Rivas suggests that salicylic acid is one the most common forms of beta hydroxy acids.

Derived from chemical salicin, (an ingredient often found in aspirin) this acid has strong anti-inflammatory and anti-redness benefits. Salicin, he says, is another form of BHA, but it does not have the same exfoliation properties as salicylic acid when applied topically.To use beta hydroxy acids properly, Rivas cautions not to go overboard with salicylic acid.

Rivas also warns of the misconceptions surrounding both alpha and hydroxy acids, as he says anyone can use these products if they are free of irritants and are formulated at the right pH level. He recommends using hydroxy acids formulated at a pH lower than 4.0, as higher concentrations can be extremely irritating to the skin. However, when using both AHA and BHA products, you’ll want to make sure to avoid certain irritants. Too much alcohol and essential oils can cause the skin to have a harder time tolerating both hydroxy acids.

“A pH of 3.5 to 4.0 is an ideal range for exfoliation to occur without provoking sensitivity,” he adds.

But at the end of the day, Rivas says both hydroxy acids are more than beneficial. When used on a daily basis, they help manage breakouts, fix uneven tone, and promote new cell turnover.

“Alpha hydroxy acids (AHAs) and beta-hydroxy acid (BHA) are two sides of the same coin,” he suggests. “Both gradually exfoliate by dissolving dead skin cells on your surface layers—so both are great for improving tone and texture—BHA just goes a little further to do the same from inside the pore.”
