I think this mask would be really ideal if you have a lot of time to spare or if you’re on a plane and you need to keep your skin hydrated. When I tried mine for the first time, I put on a lot of serum on my face and then used the mask to lock in all that goodness and allow my skin to absorb all of it. I couldn’t foresee myself sleeping in this mask so I put on a movie that was about 2.5-3 hours long and by then most of the mask was transparent except for the sides of my nose. I was really impressed at how well the mask adhered to my face and how it was so smooth unlike traditional sheet masks on me. I used the small extra bits of the mask as a lip mask and as an under eye mask by putting them over the mask. My skin felt very hydrated and plump afterwards and there was a slight brightening effect.
