Among the numerous pathways and mechanisms involved in the complex phenomenon of aging, recent findings have designated oxidative processes as a major extrinsic cause.1, 2 Our skin is exposed daily to environmental stresses such as pollutants or UVB radiation that induce a number of oxidative insults primarily to the biological membranes of skin cells.
Pollution and Aging: Antioxidants for Skin

Abstract: Cell membrane-derived lipidic hydroperoxides, introduced into the skin by environmental stresses, seem to be key players in oxidative stress-mediated extrinsic aging. Imidazole-containing peptidomimetics can protect against their toxicity through a variety of mechanisms.
Z-COTE LSA provides broad-spectrum protection from long wave UVA rays and medium wave UVB rays by physically scattering, reflecting and absorbing solar radiation.
