Used it a few times now and I am obsessed! 

This truly plumps up the lines on my undereye and makes me look away and alive. I have repurchased this multiple times.

I bought this eye serum because I have dark under eye circles. The serum definitely hydrates my skin, but unfortunately it didn't do anything for my dark circles. Wouldn't buy it again

The caffeine in it really helps to depuff tired groggy looking eyes in the morning. It's my go-to morning eye cream for that reason.

I use this one in the mornings, and whilst it does absolutely nothing for dark circles, I do get the feeling it helps me wake up. Might be placebo, but if it works, it works I suppose. And it is some extra tlc for my dry under eye area, so that's nice.
