What kind of scars do I have? Is subcision good for my scars? (photo)

To a limited degree subcision can work, but you do have atrophic scars. Subscision only breaks the bonds that hold this scar down, but you have loss of connective tissue, including collagen elastin and other scaffolding. Ideally I combine this with dermal fillers. If subcision alone was used- 3 sessions may give you 20-30% improvement. You can dermal graft the area, pros and cons in the web reference, you can try PRP, you can use autologous blood, even saline -off all these methods filler provide the most reliable method. You do need to subcise WITH filler or 'donut effect' will happen- filler goes to areas of least resistance - namely around  your scar. See a Plastic or Dermatologist near you for a full examination including palpation to determine the amount of fibrosis. Wish you well. Dr Davin S. Lim. Brisbane Australia. Acne Scar Specialist.
