Also known as ubiquinone, it is a vitamin-like, fat-soluble substance naturally present in the body.
A handful of studies have shown that coenzyme Q10 (CoQ10) may help improve the appearance of signs of aging (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 environmental factors deplete the presence of CoQ10 in the skin. The latest research suggests that topical application of CoQ10 has antioxidant and skin-soothing 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).
