Alpha lipoic acid and skin care
Alpha lipoic acid applied on the skin can reduce wrinkles, minimize fine lines and improve the skin's overall texture. As this antioxidant has several skin and health benefits, it is found in many skincare products to protect the cells and promote cell regeneration.
As alpha lipoic acid turns glucose into energy, it also protects the cells from free radical damage. Its protective mechanism of action is responsible why it is able to work wonders on the skin—either as a topical skin cream or taken as a dietary supplement.
Alpha lipoic acid's power as an antioxidant and its direct benefits on the skin have been suggested by researchers. As the antioxidant generally protects cells from damage, it will also help in improving the appearance of the skin, such as its tone and texture. In fact, in some studies, it has been shown that applying alpha lipoic acid diretly on the skin can make the skin look younger and smoother. One little caveat, though: despite alpha lipoic acid's general improvement of the skin's looks, it has not been consistently shown to completely remove wrinkles. So expectations should still be realistic.
Alpha lipoic acid's skin applications
In several studies published by Yale dermatologist Nicholas Perricone, alpha lipoic acid has been shown to effectively reduce the appearance of wrinkles (note that this says "reduce" and not completely remove). Sniffing the pecuniary benefits of his findings, Perricone eventually created his own skincare line containing high concentrations of the substance.
Aside from its topical applications, it is believed that taking alpha lipoic acid supplements can also have the same overall effect on the skin, aside from taking care of the inside of the body. It is logical, anyway: if you're healthy inside and out, that will lend your skin a vibrant, healthful appearance.
