This eye cream has saved my under eyes and eyelids. I have very delicate and sensitive skin prone to dermatitis, this cream keeps it under control.
Love it, lupus skin approved.
Was surprised
I don't have very bad dark circles under my eyes but I have been using this daily. At first I didn't see anything beneficial about it. But I do think it is quite moisturizing as an eye moisturizer and it doesn't sting. One day I was doing my usual skincare and to my horror I saw obvious under eye dark circles. I applied this, and within a few minutes, the dark circles went away! It Show more
