Hello there! Great questions, thank you! This routine is just one of my many routines and is most basic one. It does however incorporate all necessary skincare steps: double cleansing, exfoliation, hydration and peptides shot (Matrixyl + hyaluronic acid serum), skin brightening and blemish control (Niacinamide serum), and finally skin barrier protection and renewal (ceramides moisturizer). More on other kinds of skincare routines, actives, serums and skincare how-tos please visit my skincare website https://mblovesskincare.com/ . I hope you will find there answers to your skincare questions. Regarding tretinoin/retinol I hope this post would help: https://mblovesskincare.com/2019/02/12/retinol-state-of-mind-drunk-elephant-a-passioni-retinol-cream-review/ For any other question don’t hesitate to ask. Keep safe!

Hello there! I always recommend La Roche Posay, my absolute favourite French Pharmacy brand. Never has disappointed me.

Hi there! I use them both mixed and applied as cocktail or first Matrixyl and then immediately Niacinamide. They are both water based serums and compatible with each other, no matter order. When I use pure Hyaluronic serum I usually put it first before other water based serums. I hope this helps.
