Two new studies published in the Journal of Cosmetic Dermatology have revealed promising effects of krill oil supplementation on skin barrier function.
The research, which involved 101 healthy adults with normal to slightly dry skin, explored the impact of different krill oil doses on transepidermal water loss (TEWL) as well as secondary outcomes like skin hydration, elasticity, and the omega-3 index.
“For years we have looked at how krill oil can positively impact skin health,” said Katina Handeland, PhD, Director R&D, Human Nutrition.
“Omega-3 EPA and DHA modulate the lipid composition of skin cell membranes and their associated lipid mediators, thereby supporting skin barrier function.
“Phospholipids have a unique molecular function enabling them to both attract and repel water, which enables them to retain water within the skin. Additionally, both dietary essential fatty acids and phospholipids have shown to give a positive impact on skin ceramide levels, which are known to decline with age.”
Both studies showed that daily intake of krill oil, at 1 g and 2 g doses, significantly enhanced skin barrier function, improved hydration, and increased elasticity compared to a placebo group.
The randomised, double-blind, and placebo-controlled studies were conducted by Aker BioMarine together with a scientist from the Faculty of Health and Wellbeing, University of Sunderland, UK.
Over 12 weeks, participants consuming krill oil exhibited a dose-dependent increase in their Omega-3 Index, correlating with reduced TEWL and better skin hydration and elasticity.
