Hi Periwinkle, I am new to this forum, but have read in great detail your knowledge of skin care, particularly when it comes to tretinoin. I am a user of tretinoin and I buy it online without a rx (hope I'm allowed to say that, btw). Anyway, I can't pm you since I am a noob. I noticed in a thread that you helped someone else out by pm'ing them (they were a noob 2). Would you pm me and share some more information with me concerning purchasing this product without a rx and whether I am getting the best deal and the strength that I should be using. I started out using a .025% concentration and now am using a .05%. Since graduating to this strength however, I have this awful red, peeling skin under my nose and above my lip, which looks horrible when I apply my foundation. I try to only use this every other night, but may need to cut back even more. Also, could you tell me more about the green cream that I keep hearing about. Maybe this would be an option to use in between? Thanks for your response in advance!
