I've only used this product three times (not in a row), what struck me each morning was how calm my skin was - I have hormonal/side effect of endo maybe acne, large, painful, deep pimples that take forever to make their way to the surface stretching and rupturing lots of layers of skin as they come through. This mask saw them calm and practically disappear overnight. Just based off these couple of times using it, I'm so impressed and the only reason I haven't used it more is because I'm finishing up some other VitC heavy serums that I don't want to mix with the mask.
