Therefore, it was only a matter of time before the so-called "king of carotenoids" would find its way into our bathroom cabinets by way of bottles and tinctures. "Astaxanthinis an antioxidant and it can be used topically on the skin," says King. Astaxanthin is a naturally-occurring carotenoid, a red pigment that the microalgae produce as defense mechanism against harsh environmental conditions. As a bonus, it's ultra-lightweight and suitable for all skin types, even sensitive.
} It has been proposed that cholesterol is first sulfated in the lower epidermis, and then desulfated back to cholesterol in the outer epidermis [45] Disruption of this cholesterol sulfate cycle by chronic UVA irradiation might partly account for the abnormal desquamation of photoaging, and dietary astaxanthin may contribute to improving this disruption. The distance from the lamps to the mice was approximately 18 cm, and fans circulated the air. The thermal cycling conditions were 15 min at 95C for 1 cycle, followed by amplification for 43 cycles with melting for 15 s at 95C and annealing and extension for 30 s at 60C.
