Skin Health Benefits of Alpha Lipoic Acid

Alpha lipoic acid is an antioxidant and plays a role in the cell turnover process. It is a natural substance produced by the body, but is also found in some foods and is available as a supplement. Alpha lipoic acid has several skin and health benefits, and is found in many skincare products to protect the cells and promote cell regeneration.

Significance

• Alpha lipoic acid helps the body turn glucose into energy. It also works to reduce the effects of free radical damage in the body, which can damage skin tissues, organs and cause disease. Alpha lipoic acid is both fat- and water-soluble, and is readily found in red meat, yeast and organ meats such as liver. Preliminary studies suggest that alpha-lipoic acid may be used to treat certain degenerative diseases, and may also have some skin benefits when applied topically or when taken as a supplement.

Potential Skin Benefits

• Since alpha lipoic acid is a powerful antioxidant, some researchers suggest that it can benefit the skin cells. Some theories suggest that because the antioxidant protects cells from environmental damage, it will help to improve the texture and tone of the skin.
  Some clinical studies show that high potency lipoic acid applied topically can reduce wrinkles, minimize fine lines and improve the texture of the skin overall to create a youthful appearance. However, results are varied and have not been consistent enough to deem alpha lipoic acid to be a "wrinkle cure" of any kind.

Skin Applications

• Dr. Nicholas Perricone, a Yale dermatologist, has published several research studies that suggest topical application of alpha lipoic acid is effective in reducing the appearance of wrinkles, and he has created his own skincare line with products that contain high concentrations of alpha lipoic acid.
  Alpha lipoic acid can be taken as a supplement to improve the health of the cells throughout the body and have positive effects on the skin. Alpha lipoic acid can be found in many skincare supplements designed to improve the texture of the skin and create a more vibrant, healthier appearance.

Theories/Speculation

• Even though alpha lipoic acid is often touted as an "anti aging supplement" or "wrinkle treatment," there are no cohesive clinical studies available that support these claims.
  In addition to potential anti-aging benefits, studies are under way to determine if alpha lipoic acid can help reduce skin inflammation and detoxify the body and skin.
  Some research suggests that alpha lipoic acid may also help reduce blood sugar levels in diabetics. If this theory holds true, people who are suffering from acne, rosacea and other skin problems that are triggered by fluctuating blood sugar levels may benefit from alpha lipoic acid supplementation.

Misconceptions

• Since alpha lipoic acid is produced readily by the body, humans do not typically have an alpha lipoic acid deficiency. Side effects of taking alpha lipoic acid as a supplement are still unknown, so anyone who has any type of medical condition should consult with her physician before taking the supplement.
  Women who are pregnant may not be able to take alpha lipoic acid supplements because of potential side effects.
