This is a huge NO from me.
The mask is so drenched in liquid that it drips all over the place while you are putting in on and then even after you lie down, the liquid continues to go down the neck, behind the ears, everywhere...I can simply imagine what it would be if I was upright.
And this wouldn't be the end of the world if the serum didn't simply refuse to soak up, it stays on top of the skin forever. I usually apply the remaining serum on my neck and arms several times but with this one no such luck. I had to remove it physically to continue with my routine.
