Posted by Chantel M. Contributed by US National Library of Medicine National Institutes of Health

According to the study of "Natural options for the management of hyperpigmentation" by Leyden JJ, Shergill B, Micali G, Downie J, Wallo W., posted in US National Library of Medicine National Institutes of Health, researchers indicated that a few of the ingredients (e.g. soy) are supported not only by in vitro results but also by a body of controlled clinical efficacy studies; other ingredients, instead, are backed mostly by in vitro data and a few small uncontrolled clinical studies. In this review, we describe the most common natural ingredients used for skin depigmentation and their major published studies: soy, licorice extracts, kojic acid, arbutin, niacinamide, N-acetylglucosamine, COFFEEBERRY(™) and green tea.
