I've used a lot of sheet masks and have experienced hits and misses. These It's Skin The Fresh sheet masks are definitely among the hits.
They're made with a "cushion pulp sheet mask" which makes the actual mask feel super luxurious, thick, and cushiony. The mask is so soft it feels like cashmere on your skin. I'm a total fan.
The serums were not too thick but viscous enough where they felt concentrated and not too watery. The ingredients are gentle and natural and they were good to my sensitive skin.
The highlight of these masks, however, is the actual sheet mask itself, which is far superior to 95% of masks out there.
You can purchase these here for $3.00 per mask. Try them out!
