Caffeine
From our morning coffee to our favorite eye cream, caffeine, a stimulant, has worked its way into many facets of our everyday routines. In fact, caffeine is probably an ingredient in more of your skin care products than you expect! It’s been speculated that caffeine is anti-inflammatory, causes vasoconstriction, or the (temporary) shrinking of blood vessels, and contains antioxidants.
Benefits: Caffeine may reduce puffiness, redness, and protect the skin from free radicals. This means it can be an anti-aging cornerstone.
Skin Types: Most skin types can use caffeine. Those with morning puffiness are most likely to benefit.
