This review of chaga mushroom research shows it contains compounds with antioxidant, anti-inflammatory, and antiviral properties — but here's the honest part: most studies focus on pharmaceutical and cancer applications, not skincare. The cosmetic potential exists in theory, but actual skin-specific research is limited.

This is a literature review that surveyed existing research on chaga's chemical composition and bioactivities across multiple fields, rather than a new clinical study testing chaga on human skin.
