Fatty acid used in cosmetics as an emollient, antioxidant, and cell regulator. GLA is considered to promote healthy skin growth and is an anti-inflammatory agent. GLA is found in black currant oil or seeds, evening primrose oil, and borage oil (Source: Biochemical and Biophysical Research Communications
, March 17, 1998, pages 414–420). However, there is no research showing GLA to be effective in the treatment of wrinkles (Sources: British Journal of Dermatology
, April 1999, pages 685–688; and Dermatology
, 2000, volume 201, number 3, pages 191–195). When taken orally, GLA has been shown to have some anticancer properties, but there is no research showing that that effect translates to skin.
