Role of ingestible carotenoids in skin protection

A new article published in Photodermatology, Photoimmunology and Photomedicine stated that carotenoids – a class of phytonutrients, are effective in boosting the skins innate resistance against ultraviolet (UV) B-induced erythema (sunburn). The authors informed that many clinical studies have focused on the measurement of erythema as the primary clinical indicator of skin protection against UVB radiation. While more recent studies have shown that carotenoid supplementation provides a greater degree of skin protection than previously shown; new clinical and molecular endpoints beyond UVB-induced erythema have been reported. In addition, carotenoids provide photoprotection against UVA-induced pigmentation and inhibit molecular markers of oxidative stress, for instance – intercellular adhesion molecule 1, haem oxygenase-1 and matrix metalloproteinases 1 and 9. This art...
