Amino Acid Cleanser May Help Improve Acne and Oily Skin

Researchers studied an amino acid cleanser containing salicylic acid, glucuronolactone, and ceramides for 28 days. They found that it may help improve skin barrier function, reduce acne, and improve skin texture and moisture content. However, more research is needed to confirm these findings.

Why it matters: This study may help skincare experts understand how certain ingredients can improve acne and oily skin conditions.

A small sample size of 42 volunteers was used, and the study only lasted for 28 days.
