As part of the eye-obsessed Iris collection, Iris Firming Pm Eye Serum is a powerful yet gentle overnight eye serum that helps firm the eye contour, so you wake up with a visibly rejuvenated look every single day. The potent treatment is formulated with an expert blend of retinol to help smooth out fine lines and wrinkles, and mushroom extracts to hydrate the skin for improved elasticity - all while fighting free radicals as you sleep. Ideally, combine with the Iris C-Concentrated Eye Cream and Iris 2 Illuminating Eye Massager to push the serum into deeper skin layers for staggering results.
