I love ALL of the Cosrx products I have tried and I was excited about using this, since I'm a huge fan of nighttime masks. This was disappointing to an extreme degree, an overall horrible product that only produced me with negative results. Very sticky, uncomfortable on the skin, doesn't absorb well, and didn't feel any better in the morning. It caused little whitehead break outs, and made it hard to sleep at night because my face would stick to my pillow. I used this twice and then it gathered dust in my bathroom closet until it expired.
