Dew of the Gods Filla retinol mask is a slow release overnight mask containing retinol and Vitamin E to soothe and revive dull and tired under eyes. It tingles just a slight amount, but that lets you know it is working. This under eye mask has been one of my favorites for awhile now and has really helped with my under eyes. I also love it’s cooling feeling as well as it’s light scent. With this mask, you need to make sure your skin is completely dry before applying to your under eye.
