There was a stage, twice actually, when the pores on my nose shrunk so much, which really means the sebaceous glands shrunk, that it was completely covered in sebaceous filaments every morning. The pic isn't my nose, but they were like this, but extended out further, like hairs, and felt like sandpaper.
It occurred at high doses, first around. 120mg then again at 160mg day. I stayed at each level until it stopped, about a week.
I don't know for certain, but I suspect the low dose. long term protocol wouldn't have ever managed to accomplish that incredible clearing out. Also, the torso is the hardest area for accutane to exert its effects, and again, it wasn't until the highest daily doses that the impact was seen on my shoulders.
You can see it "moving around" different areas as you go through the course, as each section starts with a worsening to one degree or another. For me it was slight, but it started with my forehead, then face, then stomach (where I never had acne but developed a little in this short lived "purge" stage), etc. At the highest doses months in it finally had a major impact of my back, then finally shoulders. Along the way it hit the nose hard with above described effect. It was surreal. Could not make out a single pore on my nose, and covered in a forest of those filaments.
Most accutane research focuses on the face, with the body receiving much less attention, but it's acknowledged higher doses are generally required to "reach" some areas.
