What it is
An alkaloid compound naturally found in coffee, tea, and cacao plants. It is known for its stimulant effects when ingested and has several topical benefits for skin.
How it works
Topically, caffeine is a vasoconstrictor, meaning it can temporarily constrict blood vessels, which may help reduce redness and puffiness. It is also a potent antioxidant that can neutralize free radicals. It can penetrate the skin and may improve microcirculation.
