I am 40 days post op brachioplasty. This is a pic of my arm - is this scar normal or hypertrophic? (Photo)

It does look hypertrophic in this photo. Silicone sheeting can work really well on hypertrophic scars, if the scar is unresponsive to that steroid injections may be needed.  I would recommend getting in to your physician and talking about treatment options as there are many. 

Brachioplasty can sometimes result in scars that are wide or thick. Scars take about 12-18 months to significantly mature so that they appear finer and the color fades. At 40 days postop following brachioplasty, you are early in your recover. However, it does appear that you have developed hypertrophic scars. You should follow-up with your surgeon for recommendations about how to treat these scars. Treatment may include scar massage, silicone scar therapy and even corticosteroid injections.

Hello Sana Ali, thank you for your question. Congratulations for having
undergone a brachioplasty. I would still
suggest arm compression for another 2-3 weeks. This should help flatten the
scar. If the scar does not flatten, then you may be a good candidate for
steroid injections. Another option is using a V-beam laser. The laser will help
soften the scar.

Sincerely,

J. Timothy Katzen, M.D.
