The Relove By Revolution Eye Serum is like a double espresso for your delicate skin. With this product, even after a sleepless night, you can regain a fresh and vibrant look. The secret lies in caffeine, which is a key component of the serum. It’s an antioxidant that constricts blood vessels, thereby reducing puffiness and lightening dark circles under the eyes. In synergy with other active ingredients, caffeine seemingly awakens the skin, eliminating all signs of fatigue, stress, or lack of sleep.
