Supplementation of flaxseed oil diminishes skin sensitivity and improves skin barrier function and condition
The study explored the impact of dietary fatty acids on skin sensitivity by administering daily supplements of flaxseed oil and safflower seed oil to two groups of female participants over 12 weeks. Assessments included skin sensitivity, hydration, water loss, and skin surface properties, measured at the beginning, midway, and end of the study. The flaxseed oil group experienced notable improvements in skin sensitivity, reduced water loss, less roughness and scaling, and enhanced smoothness and hydration, alongside a decrease in the plasma n-6/n-3 fatty acid ratio. The safflower seed oil group saw improvements in skin roughness and hydration, though these changes were less significant and occurred later compared to the flaxseed oil group, and this supplementation resulted in an increased n-6/n-3 ratio. The findings suggest that flaxseed oil, in particular, effectively improves skin conditions in individuals with sensitive skin.
