What it is
Inositol hexaphosphate from plant seed storage; multidentate metal chelator binding iron, copper, and zinc ions that catalyse reactive oxygen species generation in skin; chelation limits tyrosinase activity by competing with copper at the enzyme active site; mild exfoliant activity at low pH; used in antioxidant and tyrosinase-targeting formulations addressing post-inflammatory pigmentation; good tolerance profile and broad formulation compatibility.
Where it sits
Serums sit after toner and before moisturiser. Thinnest to thickest, water before oil.
