The Ordinary Caffeine Solution 5% + EGCG is a targeted eye serum containing a high concentration of caffeine and green tea-derived EGCG. This lightweight formula helps reduce the appearance of dark circles and puffiness around the eye contour area while providing antioxidant benefits. This product contains 5% caffeine supplemented with highly-purified Epigallocatechin Gallatyl Glucoside (EGCG) from green tea leaves. It should be noted that hollowness under eyes caused by structural factors and permanent puffiness from fat deposits cannot be addressed by this topical solution. The product comes in UV-protective packaging since EGCG is light-sensitive. Apply a small amount around the eye contour area morning and evening for best results.
