Pomegranate extract is rich in antioxidant and anti-cancer properties. Skin care formulations containing this extract are able to improve the appearance of wrinkles and decrease inflammation. A 2013 study by Rana et al. found that Pomegranate fruit extract inhibits melanin production and shows promise for use as a skin-lightening agent. These scholars identified a compound, called punicalagins, as the active melanin inhibitor in the extract based on its capacity to inhibit melanin production. Furthermore, it has been proven that extracts from Pomegranate peel has an inhibitory effect on the collagen-depleting substance MMP-1. Research has also found that Catechin, which is an active content of Pomegranate extract, protects skin against UVB-induced oxidative stress and markers of photoageing, and thus, might be an important substance in skin care formulations.
