Alpha-Lipoic Acid for Aging Skin & Wrinkles

C Some Evidence Limited evidence from small studies, but some positive signals exist.

Research suggests oral ALA (300 mg/day) may reduce facial wrinkles and improve skin texture. As a universal antioxidant, it may also reduce AGE formation relevant to skin aging.
