There are so many speculations if collagen is able to be absorbed by the skin at all. Besides the speculation, this mask is actually difficult to stay put and on especially while sleeping . The only good thing about this is that it comes with extra pieces for areas around the mouth and forehead. Besides that, this product is not something that can give you results in a single use or even after 4 uses. Its simply a fancy mask, i would prefer their hydrating one over this but even with that, it would still be difficult for it to stick to the face
