Skin Health

Oxidative stress plays a major role in the aging process. Exposure to UV radiation results in the production of reactive oxygen species and inflammation.  This process results in the breakdown of the extracellular matrix – collagen and elastic fibre – leading to the formation of wrinkles (1). The body’s ability to counteract the excess generation of free radicals is diminished with age. Clinical studies have shown that oral supplementation of astaxanthin results in a decrease in fine lines and wrinkles, higher skin moisture, and increased elasticity (2). Astaxanthin was shown in a recent study to inhibit inflammatory cytokine and matrix metalloprotease secretions in cells exposed to UVB radiation (3).
