The Ordinary Caffeine Solution 5% + EGCG is a potent formula designed to target under-eye puffiness and dark circles. Infused with caffeine and Epigallocatechin Gallatyl Glucoside (EGCG) from green tea leaves, this lightweight serum works to reduce the appearance of tired, puffy eyes and diminish the look of dark circles. Caffeine is known for its ability to constrict blood vessels, which can help reduce swelling and puffiness around the eyes. EGCG, a powerful antioxidant, helps to combat free radicals and reduce the appearance of dark circles. The fast-absorbing, non-greasy texture makes it suitable for daily use, leaving the delicate eye area looking refreshed and revitalized.
