Indented Columella Scar More Noticeable over the Years? (photo)

The photo you've provided does appear to show a significant indent in your transcolumellar scar. It is hard to tell for sure without seeing a profile view but dermabrasion likely will not provide enough benefit to camouflage the scar. Scar revision (cutting out and replacing the widened scar with a finer scar) is likely the best option. Seek an in person consultation with a Facial Plastic Surgeon for more specific advice. I hope this information is helpful.Stephen Weber MD, FACS

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

Your picture is not ideal to view your scar, but if your columellar scar is depressed, it's possible that a filler could be used to help raise it and make it less noticeable.  The other option would be to have the scar surgically revised.
