Will microneedling work on this scar on my nose? (photo)

Yes, miconeedling can help give improvement, but I recommend a combination approach for best outcomes. I recommend microneedling combined with prp, lasers, subcision and fillers to get the most improvement. See an expert. Best, Dr. Emer

Yes, most definitely!  Microneedling creates discrete wounds using a specialized tip containing motorized thin needles which prick the skin surface to stimulate growth of new collagen - a process called collagen induction therapy. During treatment, tiny blood vessels get pierced, releasing growth factors that promote new collagen.  With this in mind, this technique is beneficial for fine lines, surgical scars, acne scars, and overall skin rejuvenation.  Adding platelet-rich plasma further enhances the benefit of this treatment.

Microneedling, especially when combined with PRP (protein rich plasma) is good for improving the appearance of any scars, not just acne scars.  I do think a series of 3-6 would be beneficial for the scar on your nose.  However, I always tell my patients that nothing is available to make scars go completely away.  Your scar looks deep, which means microneedling should soften it, but it likely will always be visible. Best of luck to you.
