I have an obsession with all things under eye whether it be cream or patches. After using these, I will never go back to any retinol eye patches. I like the little spooly included in the product because I can gently get the patches cleanly out without touching others. I keep these in my skincare fridge. They feel so cool and comfortable when applied. They stay under my eye well and I can feel the tightening and hydration immediately. The Peter Thomas Roth Even Smoother Glycolic Retinol Hydra-Gel Eye Patches are formulated with Niacinamide, 1% Glycolic Acid, all to hydrate, smooth, firm, and plump my under eyes for a youthful, bright-eyed glow! After one use, my puffy eyes are gone! With the continuous use, I am excited to see how much my line lines and crow's feet diminish. I will continue to purchase this product to see ongoing results and highly recommend you give it a try!
