I used the Cryo-Recovery Eye Serum in my skincare routine both morning & night. It is like an ice gym for my skin because it gives such a wonderful cooling sensation when applied with the metal tip on the component, and tightens the undereye. This makes my eyes look wide awake instantly, while also depuffing, smoothing, & brightening my orbital area. It feels absolutely delicious & I definitely notice *temporary* visible results, but nothing that is long term & nothing that resolves my fine lines.
