What is Alpha Lipoic Acid?
Alpha Lipoic Acid (ALA) is a naturally occurring compound found in every cell of the body. It helps turn glucose into energy and also functions as an antioxidant, neutralizing free radicals.
ALA is primarily used in skincare and makeup products for its antioxidant properties, which may help protect skin from environmental damage. As a dietary supplement, some believe ALA supports health by reducing oxidative stress, though evidence on such benefits is varied.
When you see Alpha Lipoic Acid listed on a label, it typically functions as an antioxidant to stabilize the product and potentially offer benefits to skin appearance.
Commonly found in: foundation, anti-aging creams, serums, sunscreens
Benefits
- Functions as a potent antioxidant, protecting skin and cells from oxidative damage.

The FDA recognizes ALA as a dietary supplement ingredient, but does not assign it specific health claims.
Studies have demonstrated antioxidant benefits, but results on health impacts such as improved skin appearance are mixed.
Alpha Lipoic Acid is typically synthesized in a lab and is considered vegan-friendly.
