You've tried the creams, the serums and the one your friend swore by. Most of them did nothing, and you're done paying for promises. So before you spend another dollar, here's what you should know about PDRN.

1

It helps thin, tired skin look plump again

As we get older, skin gets thinner and loses its bounce. That's why you can look tired after a full night's sleep.


PDRN comes from salmon. It helps your skin hold onto moisture, so it looks fuller and firmer again.

2

It starts working the moment it touches your skin

There's no waiting for it to soak in. The mask is loaded with 40mg of PDRN serum and starts hydrating as soon as it's on.


Your skin feels softer and less tight, before you've even turned off the light.

It works in 20 minutes

Most sheet masks need hours, or a whole night, and slide off onto your pillow.


This one is bio-cellulose. It clings like a second skin and does its work in 20 minutes. When it turns clear, it's done.

Two masks keep your skin hydrated throughout the week

First usage gets you softer skin. Eight weeks gets you a difference people can see.


  • Week 1: skin stops feeling tight after you wash it.

  • Week 2-3: dry lines around the eyes and mouth look softer. Makeup goes on easier.

  • Week 8: skin looks firmer and smoother. The last mask goes on the night before.

Twice a week is all it takes

There's no 10-step routine and nothing new to learn.


Wash your face, put on the top piece, then the bottom piece. When it turns clear, peel it off and pat in what's left. One box lasts two weeks.

"Being older, I wasn't sure if I could use this product correctly and kept putting it off. I'm sorry I hesitated."
