I think it is a great possible choice. YOU will need to discuss all risks/benefits with your dermatologist. Make sure you see a dermatologist who is comfortable with prescribing accutane.
You will need to be evaluated by a Board Certified dermatologist to see if it is truly acne returning and discuss all treatment options. It could be a number of things including recurring acne.
Isotretinoin can affect people differently. Some patients do complain of GI upset but usually these symptoms are mild. Make sure you are taking your medication as instructed with food.
Thank you for providing the photo and stats. The number of treatments required for patients varies. I recommend scheduling a consultation with a physician to access the skin under your skin to determine the amount of treatments you need based on the results you are wanting to achieve. Physicians can create a treatment plan specifically for you so that you can get the results you want whether you get Kybella, Coolmini or Ultherapy. Hope this helps. Wishing you the best, Dr. Rana Mays
