Astaxanthin Associated With Improved Skin Health
Oxidative stress accelerated skin aging. A recent study suggests that daily consumption of astaxanthin may help reduce oxidative stress and improve facial skin health in middle aged adults.
Participants in the study included 17 men and 14 women over the age of 40 who were given 4 mg of astaxanthin daily for four weeks. Residual skin surface components samples were collected from the surface of the facial skin at the beginning and end of the study. Blood samples were taken on days 0, 15, and 29 in order to measure plasma levels of malondialdehyde (MDA) for use in assessing systemic oxidative stress.
The researchers noted an 11% reduction in MDA at the two-week point and a reduction of 22% at the four-week point. They also noted statistically significant reductions in corneocyte desquamation and microbial presence, both markers of an imbalance in the skin, at the conclusion of the study.
Researchers from Saratov State Medical University in Russia conducted the study. It was published on October 10, 2017, in Nutrition Research.
Astaxanthin is a carotenoid found in red-colored vegetables and fruits. It has been shown to improve eye, skin and joint health and boost cognitive function. If you’re looking to increase your dietary intake of astaxanthin, consider consuming more salmon, rainbow trout, krill, and red-pigmented vegetables and fruits.
