Can I apply Tazorac with TNS Essential Serum or are the two incompatible together?
Hi Doctors :). I use Tazorac for wrinkle prevention. I also use TNS Essential Serum for wrinkle prevention. At night time, can I apply TNS Essential Serum first and then apply Tazorac on top of it? Will my Tazorac and TNS still work? Also, does TNS Essential Serum do what it is marketed to do? Can the growth factors in the product actually benefit aging skin or is this just marketing?
