I've tried many of the Garnier sheet masks recently and this one was the worst by the long shot.
There was so much liquid in the packet you can't help but make a mess getting the mask out. It's super sloppy which makes it really hard to unfold the mask and stick it on your face properly. The fask also slips down your face much more than the other varieties.
I found that the serum didn't really absorb in the 15min time frame so it had to be rubbed in and left alone for a long time after talking the mask off (good thing I had lots more Downton Abbey to watch!).
In the end my skin did feel nice and hydrated but I'm not sure it was worth the hassle given I had better results with the other masks and with less fuss required.
I have no doubt that I have glorious hydrated skin after using this, but the design was awful, the eye/mouth holes were so small that I actually had to cut them with scissors to be able to use the mask and even then the serum was too close to my eyes for my liking, and was touching my skin around my nose. If it was a gel or serum I would use it again but not as a sheet mask.
