“Wakes up tired eyes and protects skin from UV-induced damage.”
What it does
Topical caffeine is a methylxanthine that constricts blood vessels (vasoconstriction), reducing puffiness and dark circles around the eyes. It is also a powerful antioxidant that has been shown to neutralise UV-induced free radicals and reduce photoageing. It absorbs well through skin and is effective at relatively low concentrations.
Benefits
- Reduces under-eye puffiness by constricting blood vessels
- Antioxidant protection against UV-induced free radical damage
- May reduce the appearance of dark circles over time
