Medik8 r-Retinoate Day & Night Eye Serum
The eye-area version of r-Retinoate, built around the same molecule and the same principle: retinyl retinoate is photostable, so it can be used morning and night rather than evenings only.
That matters more here than anywhere else on the face. Eye-area skin is the thinnest on the body and the least tolerant of vitamin A, which is why most people either avoid retinoids around the eyes entirely or use something too weak to do anything. Encapsulating the molecule slows its release, and Medik8 substantiate it as eight times more powerful than standard retinol while staying gentle enough for twice-daily use on delicate skin.
It isn't only a retinoid, though. Caffeine and hesperidin work on puffiness and the look of dark circles, and multi-weight hyaluronic acid holds hydration in an area that shows dryness before anywhere else. So it addresses the three things people actually complain about — lines, shadows and puffiness — rather than just one.
A featherlight serum that absorbs quickly and layers under makeup without pilling.
