Hi! Is there a specific order to apply serums or should I switch days on which serums I use? Specifically, I use a lactic acid serum and hyaluronic acid serum. Thanks!
Hey, the hyaluronic you could absolutely use everyday am and pm. I am not sure what percentage the lactic is or if it is blended with any other acids but a few times a week at night should be good. Best bet is 2-3 x a week.
Also on the nights that you use both put the lactic on first.
