Olay Eyes Pro Retinol Eye Treatment, $29.99, is wildly hydrating and contains a form of retinol called pro-retinol, which is the most gentle of them all. This eye cream feels silky and sinks in fast without leaving behind any residue.

While you'll have to wait at least a few weeks to see results from retinol in an eye cream, Eve Lom Time Retreat Eye Treatment, $75, also contains oat kernel extract, which immediately tightens skin. The retinol in this product is encapsulated so it sinks in deeply for maximum wrinkle eradicating benefits. It also hydrates with vitamin E and squalane and brightens pigmentation with vitamin C.

Kate Somerville Retinol Firming Eye Cream, $85, has a cooling applicator that lets you massage in the product and helps diminish puffiness. It has both retinol and bio retinol — an ultra gentle form derived from seeds that helps to smooth out skin texture.

Thanks to a combination of gentle yet fast-acting retinol SA and hyaluronic acid, Neutrogena Rapid Wrinkle Repair Eye Cream, $18, plumps fine lines in about a week while working over time to get rid of deeper lines.

If you want to get rid of major crow's feet, look for a retinol eye cream with encapsulated retinol -- it's able to get down deeper into the skin. Dermalogica Age Reversal Eye Complex, $78, has a "smart" kind of encapsulation that targets wrinkles, as well as niacinamide to brighten dark circles, ash tree bark for hydration and peptides for an even greater anti-aging boost.
