I have been using a serum from the same brand and its same Blue line. It does an amazing job in moisturazing the skin. Compared to the serum, the mask is not as moisturizing but yet still highly effective. I leave it for 20 minutes and after 20 minutes my skin feels soft and nourished.Some moisturizing masks tend to break me out as I have combination skin, but this one definately did not. The shhet paper is very very soft. Softer than the other mask sheets I have tried before and fits well to the face. The only problem is unfolding it as its very soft, but thats just a small drawback. Its a very decent sheet mask and very effective.
