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 really didn't enjoy this mask at all. I found it way too slipper and the mask didn't fit my face at all. There was way too much product in the packet and when i opened it it spilled out everywhere. I left the mask on my face for the fifteen minutes it says to and i was annoyed by it the whole time by the ill-fit and slimy feeling. Once i took the mask off i waited a bit and then massaged the residue into my skin. It didn't absorb into my skin and was just sitting on top of it. The smell of it wasn't pleasant either. After i washed the residue off with a face-cloth my skin did feel softer for a while but i didn't really notice any real difference.
Tips: Open the packet over a wipe-able surface.
