Not worth $300. My thoughts are it is a good eye cream that wears well alone or under makeup, and it also keeps my eye area looking moist. But I can probably find rich eye creams for a cheaper price.
Did not regret purchasing La Mer eye cream at all. I could see a difference after using for a month. I've tried others that are over $100 but they didn't work for me at all. This moisturises and worked great for my dark eye circles.
