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
  • Protects against UV-induced skin damage and photoageing
