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. Key features: • 5% caffeine concentration for reducing eye puffiness • Contains EGCG from green tea for antioxidant benefits • Helps minimize dark circles appearance • Lightweight serum texture • 30ml amber glass bottle with dropper • UV-protective packaging to preserve ingredients The product should be applied by gently massaging a small amount around the eye contour area both morning and evening. Note that this formula cannot address hollowness or permanent fat deposits under the eyes, as these are structural concerns rather than surface-level issues. The solution comes in UV-protective packaging since EGCG is light-sensitive. For best results, patch test before first use and discontinue if irritation occurs.
