Despite years of professional and at-home use, there had never been a study comparing alpha-hydroxy and beta-hydroxy acid peels for the treatment of acne until last year. Not surprising to those who’ve prescribed and used them, both types were found to be highly effective.
Using 20 participants with mild to severe acne, researchers applied a glycolic (AHA) peel to one half of their faces and a salicylic (BHA) peel to the other half every other week for six weeks. The vast majority of the patients experienced similar, noticeable improvements on both sides after each treatment.
So, which type of peel is right for you? While AHA and BHA have comparable clarifying results, you may want to consider that the study showed more peeling and scaliness on the AHA side of the participants’ faces. Additionally, a few patients developed new blemishes on the AHA side over the course of the study.
However, this doesn’t necessarily mean you will experience these side effects, so talk to a dermatologist about making the right choice for your own skin.
