Lactic Acid is an alpha-hydroxy acid that exfoliates the skin surface by loosening dead cells. The strongest evidence comes from a 2015 human trial: In 23 women, a single application of a 4% alpha-hydroxy acid solution combined with negative-pressure physical action significantly reduced whitehead and blackhead counts at 1, 2 and 4 weeks, and reduced pore area and number at week 1, compared with AHA peeling alone. 2015 · 23 people · healthy women (mean age 30) · PMID 26032934 · The intervention was a single in-clinic chemical peeling plus negative-pressure physical action. 1 product contains Lactic Acid, at number 9 of 24 on its ingredient list.
