First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a serum with low-dose alpha hydroxy acids (AHAs) and polyglutamate acid is safe for people with dark spots left after skin inflammation (post-inflammatory hyperpigmentation). 34 Malaysian adults used the serum for 8 weeks, with skin checks at the start, week 4, and week 8. The main goal was to see if any side effects occurred, and researchers also measured skin moisture and spot changes.
