Also known as ubiquinone, it is a vitamin-like, fat-soluble substance present in all human cells. It is responsible for cell protection and production of the body’s energy.
A handful of studies have shown that coenzyme Q10 (CoQ10) may have an effect on skin and the appearance of wrinkles, most notably by reducing UV damage, stimulating healthy collagen production, and reducing substances in damaged skin that wreck havoc on its support structure (Sources: Biofactors, Volume 32, 2008, pages 237–243; and November 2005, pages 179–185; Journal of Cosmetic Dermatology, March 2006, pages 30–38; and www.naturaldatabase.com).
There is also research showing that sun exposure depletes the presence of CoQ10 in the skin. This is not surprising because many of the skin’s components become diminished on exposure to the sun. The latest research suggests that topical application of CoQ10 has antioxidant and anti-inflammatory effects. As such, it is one of many helpful antioxidants for skin, but it is not the only one or the “best” (Sources: Biofactors, September-October 2009, pages 435–441; Journal of Investigative Dermatology, 2005, volume 125, number 4, pages 12–13; and Journal of Dermatological Science, August 2001, Supplement, pages 1–4).
