Also, does anyone know if your oil/collagen/sebum barrier has anything to do with facial blushing/flushing? I know that accutane ruins your skins natural barrier because it gets rid of oil and such (which is definitely true in my case at least). For that possibility that it has something to do with flushing/blushing, i want to know how to rebuild this barrier NATURALLY. I have def learned natural is the way to go. TIPS FOR REBUILDING COLLAGEN? SEBUM?
