I had dermabrasion done in September, but I haven't seen any improvement
There are no big side effects, I'm not even red anymore, so it could be that the surgeon didn't go deep enough.
I haven't had my nose dermabraded though, and I have severe scars.Also, it probably depends on the surgeon doing the procedure.
I have white/fair skin, you mentioned your skin was darker, so that may be an issue.
My opinion is that it in general doesn't work for deeper scars (my dermabrasion didn't even improve my more shallow, smaller scars, but that's probably just my doctor).I now think that the deeper scars need to be treated with excision/subcision depending on the scar and then maybe eventually dermabraded to even everything out.
However, I'm not too familiar with treating nose scars, that may be different in some way.
Sorry this review hasn't been more positive.
For what it's worth it is a very small area of your skin and the rest of your skin is not scarred (I assume). I don't think anyone cares about it half as much as you do
