Have used this for a number of years and recently made a switch to Shisedo’s eye cream. I’ll be going back to Kiehls when I’ve finished it as it’s honestly the most nourishing eye cream out there. It doesn’t migrate into the eye and is super rich and hydrating. Just make sure your fingers are dry when applying otherwise it just slips around and doesn’t sink into the skin.

It's good!
I like it! It was the first eye cream I've used that I've actually seen a difference in my dark undereye circles and even got rid of the thick and harsh lines as well. I've been using this since high school and I like it! I'm still looking for other eye creams because I do think that there is something better out there but this is a solid choice!
