Leucoselect® (Grape Seed extract) exerts its activity through multiple mechanisms: as a free radical scavenger, through chelation of transition metals, and by inhibition of proteolitic enzymes, etc. When topically applied on the skin, it has been shown to reduce skin sensitivity to UVB irradiation. The oligomeric procyanidins contained in the extract are the active small molecular size polyphenols responsible for the biological activity.
