Wellbutrin and perfect skin

I have been taking welbutrin for about 4 years now. I am going to tell my exact dose and type since I am trying to figure out from other peoples comments if there is a difference in side effect in SR vs XL . I have taken 150 XL and the went down to 75 mg Sr because i was trying to decrease the dosage and come off entirely eventually. I have suffered with acne all the four years but thought it was stress (Daughter became type i diabetic and can't ever get her blood sugar stable and the my son developed a bone tumor not long after she was diagnosed). Anyway we finally got his problem resolved with good results but hers is a blood sugar nightmare everyday. So you can see why I thought the acne was from stress . Never even crossed my mind it could be wellbutrin. I noticed my skin was better for a while when my dose was just 75 mg sr. But alas the bone tumor came back again for my son and had to go back to 150xl. Skin has hundreds of little white tiny tiny white heads. Is this the type of acne other people are experiencing?
