Leading medical journals have published two articles recently on the potency of glycolic acid to clear acne. It’s nice to see this hard evidence come in after so many years of all of us realizing first hand that glycolic acid helps keep us clear.
The first article in The Journal of Dermatology attempted to gauge if glycolic acid peeling helps improve acne, and if it does, whether it is through its ability to kill acne bacteria (P. Acnes). The researchers found “significant improvement of inflammatory eruptions from the first application.” They also found that glycolic acid kills acne bacteria: “Each treated side (of the person’s face) had much lower numbers of colonies compared with the untreated side…”
The second article in the Journal of the German Dermatological Society summarized what we are now seeing in the medical literature when it comes to glycolic acid and acne: “Patients assess their skin as more tensile, firmer, smoother and more youthful looking after the use of AHA containing products. For mild acne, the efficacy has been proven by double-blinded, placebo-controlled randomized clinical trials.”
