Astaxanthin

Astaxanthin, the red pigment of Haematococcus pluvialis microalgae, is one of the strongest natural antioxidants known — its singlet-oxygen quenching power exceeds vitamin E by orders of magnitude. In skin, it protects lipids from peroxidation, reduces UV-induced inflammation and collagen breakdown, and studies show improved wrinkles, elasticity, and moisture over weeks of use at 0.03–0.1%. Its intensely red colour demands skilled formulation (encapsulates, emulsions) to avoid tinting the skin — handled well, it is invisible. Excellent for outdoor athletes, high-sun climates, and anti-aging routines. Combine with vitamin C/E for networked antioxidant regeneration.
