The Ordinary caffeine solution is a light-textured formula containing a very high 5% concentration of caffeine plus a highly-purified epigallocatechin gallatyl glucoside (EGCG) from green tea leaves.
Studies have shown caffeine applied to the skin can help reduce the look of puffiness and dark circles under and around the eyes. It has also been shown that caffeine can reduce the appearance of cellulite.
This amazing eye cream is hugely popular and very effective for reducing the look of both dark circles and puffiness but it is not a moisturiser. It is therefore recommended to be coupled with an eye cream specifically for the purpose of hydration and dynamic lines.
