This is a good sleeping mask, it's quite thick and I feel it does lock in the moisture. The ingredients list is amazing, full of nice and brightening ingredients. It feels pretty sticky once I first apply, but it actually goes away after a while, and in the morning my skin is bright and clear. However, I'm not crazy about the smell, which lingers for a few minutes after applying, and I wish it came with a spatula so that it would be easier to take a small portion out of the jar. Overall, it's a pretty good option for an affordable sleeping mask with nice ingredients.
