Definitely use only at night. It’s very hydrating and thick. Absorbs into skin quickly. I really like it, just don’t use in the morning under makeup, it will make your concealer patchy.
I decided to buy this eye cream mainly because of the peptides in it. I recently turned 40 and have a few fine lines around my eye area. So I'm using it to treat those lines and prevent further signs of aging. Since it's a rich cream, I use it sparingly. It's nice that it comes with a mini spatula.
