Products. Derived primarily from algae or yeasts, a wide variety of astaxanthin products are available as nutritional supplements in health food stores (Crit. Rev. Food Sci. Nutr. 2006;46:185-96). Increasingly, astaxanthin is finding inclusion as an active ingredient in topical formulations.
Philosophy’s when hope is not enough SPF age-defense sunscreen is a broad-spectrum UVA/UVB SPF 20 sun protection formulation that contains astaxanthin, tocotrienol, vitamin C, peptides, and beta-glucan. It is designed to moisturize and protect the skin from sun damage.
In addition, astaxanthin, termed "the most potent antioxidant yet discovered" by Derma E, is a staple in products from by manufacturer, including Age-Defying Night Crème with Astaxanthin and Pycnogenol, Age-Defying Day Crème with Astaxanthin and Pycnogenol, Age-Defying Eye Crème with Astaxanthin and Pycnogenol, Anti-Aging Moisturizing Complex with SPF 15, Orange Blossom Age-Defying Hand and Body Lotion, and Lavender Age-Defying Hand and Body Lotion.
ShenDea also includes astaxanthin as a main ingredient in its line of facial creams, gels and lotions, combining the carotenoid with pearl and grape seed extract.
Derma MD features astaxanthin in AstaXanthin Micro Peel; AstaXanthin Concentrate Tri-Complex, intended for postprocedural application; and "D" Puff Eye Repair Gel.
Conclusion. Along with pigmentary and other functions, carotenoids exhibit significant antioxidant activity. Much more research has been conducted on carotenoids such as beta-carotene, lutein, and lycopene than on astaxanthin, but the evidence for this latter carotenoid is compelling. The effects of astaxanthin on crustaceans and seafood are well established, but recent research suggests that this potent antioxidant has the capacity to impart significant health benefits to human beings. More research, in the form of randomized controlled trials, is warranted to determine the efficacy and safety of this carotenoid in formulations intended to benefit the skin.
