Alcohol-free, cruelty-free and vegan, The Ordinary Caffeine Solution uses skin-loving ingredients packed with nourishing antioxidants to reduce the appearance of discolouration underneath the eyes and diminish the appearance of fatigue and stress built into the skin over time. In evening out the overall tone of your complexion, the serum leaves skin feeling refreshed and reduces the pigmentation of the skin caused by dark circles.
