Here are two lesser-known health facts about the effect of caffeine on the skin:
Caffeine Can Help Reduce Puffiness: Caffeine is a vasoconstrictor, meaning it can narrow blood vessels. When applied topically, caffeine can help reduce puffiness and dark circles under the eyes by temporarily tightening the skin and decreasing swelling. This is why caffeine is often included in eye creams and serums.
Caffeine May Protect Against UV Damage: While more research is needed, some studies suggest that caffeine may offer protective benefits against UV radiation. Caffeine has been shown to inhibit a protein called ATR (ataxia telangiectasia and Rad3-related), which plays a role in the skin’s response to UV damage. By inhibiting ATR, caffeine may help reduce the risk of skin cancer and other UV-related skin issues.
