I am already using buffet and hyaluronic 2% before moisturisers. I mix them in my hand and apply together as they are both water based (think I read this somewhere).
Want to add Matrixyl to my regime - can I blend that in too? Don't have time for three applications in the morning!
Also want to add Vitamin C Ascorbyl Tetraisopalmitate - do I do that afterwards as its oil based I think??
Or am I doing it all wrong?
