Ik heb routinely 3 en 13. De drie aanbevolen druppeltjes zijn wat weinig, dus ik gebruik er vijf per keer. Maar verder wel heel tevreden. Ik merk dat mijn huid soepeler wordt.
The routine is easy to follow. I started 3 weeks ago so still to early to know if it works. My face looks healthier and feels better too but I also use other products next to it.
I'm using one of your serums. I have seen improvements in my skin already after one week. I am going to continue my skincare with you, because this is the first time I am satisfied. I have tried many products that are not needed, but finally now I have found the right one.
Makkelijk te gebruiken, goede resultaten voor mijn huid. Al na een dikke week

Barrier boost B3 serum.
Hoi! Ik ben op zoek naar een serum voor een droge huid met rosacea. Ik zou het liefst iets hydraterends hebben, waar mijn huid niet sterk op reageert. Dank alvast!
Je noemde rosacea. Om deze reden zou ik de 07 - 360° Azelaic Acid Serum aanraden in combinatie met de 06 - Soothing 5-Plant Extract Serum. Deze combinatie zou erg helpen want azelaïnezuur (uit de 07) is geweldig om ontstekingen te bestrijden en verzacht de huid. Serum 06 zal verder helpen te kalmeren. De 13 - Barrier Boost B3 Serum zou ook helpen bij rosacea en om droge huid te behandelen.

Yes, our formulation is safe to use with other acids, also Vitamin C. If you want to be a 100% sure about Niacinamide in your product not turning into Niacin, wait for the one product to dry first before applying the other.
