The Sandwich App

Retinol is, in our opinion, the best anti-aging active ingredient available on the market. (Click here to find out why)

We highly recommend using a soothing (lightweight) serum first, followed by your retinol product and finally a layer of cream moisturizing for the face.


Green Keratin Retinol-sandwich method:

1) Yellow Plasma Recovery face serum
2) RTN* (Encapsulated Retinol) serum or face cream
3) BISABOLOL face cream

* We recommend that you start this routine with the highest concentration lower in Retinol, then gradually increase, in the following order (refer to the product sheet for the frequency of application):
  • 0.3 RTN CAP BAKUCHIOL
  • RTN CAP 0.5
  • RTN PRO 0.75
  • RTN 1.0
