Hi, I've started using tret through a Skin + Me introductory offer. No progress with the tret yet but I've read great things about it so will persevere.
I'm completely underwhelmed by the rest of the Skin + Me box though and much prefer my own products, so where can I get Tretinion? I'm aware it's presumption only, how do others manage? Can I use retinol as well or no? My pores are the size of craters.
