01 WHY IT WORKS WHILE YOU SLEEP
It seals the essence against your skin for hours — in the window your skin takes in the most
A cotton sheet mask is wet for about fifteen minutes. Then it starts to dry — and a drying sheet pulls water back out of your face, which is why dermatologists tell you never to sleep in one.
This is a jelly gel sheet with no cloth in it. The sheet is the essence: 28 grams of it, set into a gel that softens with your body heat, clings like a second skin and doesn't dry out. It seals salmon PDRN, niacinamide, adenosine and a dozen peptides against your skin for one to four hours — or all night — so the water in your skin stays in your skin.
And night is the right time. Skin is more permeable in the evening than in the morning; absorption peaks around 4 a.m. This mask doesn't ask your skin to do anything. It keeps the good stuff there for the hours your skin is open for it.
