A Study to Evaluate the Effect of Fish Oil Concentrate on Skin Function

The long chain mono-unsaturated fatty acids, cetoleic acid (C22:1 n-11) and gondoic acid (C20:1 n-9) found in some North Atlantic fish have been shown to lower inflammatory markers. This has been shown in preclinical studies with particular effect in adipose tissue, and in a human clinical study measuring redness of the face. Omega-3 is also known for reducing skin erythema evoked as a response to UVB exposure, and to decreasing systemic inflammatory biomarkers.

This provides a hypothesis that a combination oil with known bioaccumulation in both subcutaneous fat and in dermal/epidermal layers will contribute to healthy skin function, as shown by a reduction in inflammatory markers and skin erythema and improved barrier function.

The study will recruit subjects to one of 3 arms, a placebo, a low dose and a high dose of omega 3-9-11. Subjects will receive capsules for 3 months and undergo a series of measurements at baseline, 6 weeks and 12 weeks.
