Vitamin D 'significantly' reduces skin redness and swelling, a new study has found.
And not only did it suppress inflammation, the 'sunshine vitamin' was also discovered to activate skin repair genes.
With participants who took a supplement an hour after a burn, the higher their vitamin d levels, the more the burn had healed 48 hours later.
The findings of the trial – the first of its kind – suggest vitamin D increases levels of an anti-inflammatory enzyme in skin.
Called arginase-1, it enhances tissue repair after damage and helps activate other anti-inflammatory proteins.
