It is no exaggeration to say that this product has the same amount of formula as a concentrated bottle of essence. I was surprised to see how much essence it really had. I apply the sheet mask in the evening the night before an important appointment, and when I wake up the next day, my skin is glowing. It’s full of moisture, so you can immediately feel how dense it is. I used most of the product, so I rushed out to buy another one. It made me realize how dry other sheet masks really are. Ever since then, I have always made sure to stock up on the product!
