Does dermabrasion works on this scar ? (photo)

I have been performing manual dermasanding or machine performed dermabrasion to improve recent post traumatic and post surgical scars (as in this case)--a technique known as "scarabrasion" with generally gratifying results since the late 1980s. Results are best if performed within eight to twelve weeks following injury or surgery. Contrary to the old dictum of "Wait a year until the scar matures,"  improvement in the appearance of the scar is best if treatment is undertaken within the critical window just mentioned and becomes increasingly less effective the longer one waits after that time. Scarabrasion is a minimally invasive process and healing typically takes a couple of weeks. More recently, in my practice, fractional microneedle therapy (aka medical microneedling, skin needling and dermal rolling) has replaced scarabrasion. Effective treatment must still be performed within the critical eight to twelve week period following the trauma or surgery (It's also used for acne scars), but the treatment is less invasive and healing is usually complete by the next day. More than one treatment session, however, is required, but since there is little to no downtime, this doesn't really present much of an obstacle to this approach. To learn more about this approach, check out "scarabrasion" and "fractional microneedle resurfacing" in the archives of Realself.com

Dermabrasion (NOT
microdermabrasion) will improve the appearance of this scar; however,
many physicians do not have adequate experience with this technique. I
still utilize it in my practice.  It's best to wait about 2-3 months after surgery to perform dermabrasion, and you should understand that more than one treatment might be necessary.  I'm glad you are on the right path and wish you well!
