Absolutely amazing! I was shocked by how much better my skin looked only two hours after using it for the first time! As a 33-year-old woman with rosacea, I could tell that it helped a lot soothing the redness on my face, gave my skin a beautiful glow and, most of all, it did so much for my dark undereye circles as no other product has ever done!!! I never thought that a product that is not even targeted at undereyes would help me that way, it was such a surprise. I have very dark undereyes caused by my eyes being so deep, no eye product had ever helped before. I think the collagen in this mask helped filling in the skin around the eyes and I can no longer live without this product, it makes me feel so happy! I just wish I had knew it sooner. My undereyes are still there, but I can cover them with so little makeup now, sometimes I don't even bother hiding them. The fine lines around the eyes and mouth are so much softer and keep getting better. I've been using it for 2-3 months now.
