This combination of astaxanthin and collagen keeps your skin young

A daily dose of 6 milligrams of astaxanthin reduces facial wrinkles, we wrote two weeks ago. And there is some evidence that hydrolyzed collagen has the same effect. What would happen if you combined astaxanthin and collagen? A human study, published in the Journal of Medicinal Food in 2014, provides the answer.

Study
The researchers, affiliated with Seoul National University in South Korea, divided 44 women aged 41-60 into a placebo group and an experimental group. During the 12 weeks of the experiment, subjects in the experimental group consumed 2 milligrams of astaxanthin and 3 grams of hydrolyzed fish collagen per day.

The collagen was a product of Rousselot, France, which markets hydrolysed fish collagen under the name Peptan. The astaxanthin came from the factories of the American Cyanotech Corporation.

Results
After 12 weeks, the researchers determined whether the elasticity and moisture of the skin on the face had changed. In terms of humidity, they found no differences between the groups, but elasticity was significantly improved in the women in the supplementation group.

After 12 weeks, the researchers irradiated a piece of skin on the women's buttocks with UV light. UV radiation is the main cause of skin aging.

The Koreans discovered that the skin of the women who had received the supplement responded to the radiation by producing significantly more pro-collagen type 1. This means that the skin tissue renewed itself.

In addition, the skin cells of the women taking the supplement produced less of the enzymes MMP-1 and MMP-12. These enzymes are involved in catabolic processes in skin tissues.

Sponsor
The study was funded by Cerebos Pacific Limited. [Wikipedia] Cerebros is the producer of RudyCollagen, a functional food containing collagen and astaxanthin, among others.
