What's is the Best Treatment for Fever Blister Scar? (photo)

I would start out with topical skin lighteners such as Melarase, followed by either ablative laser or serial excision. Raffy Karamanoukian, MD Los Angeles

A scar resulting from a fever blister is caused by the herpes simplex virus, so the virus still lives within you, and could flare again, especially if the area is treated.  Therefore, prior to any treatment you should be on, and stay on, prophylactic valcyclovir for at least ten days.  Dermabrasion or a fractional CO2 laser should smooth the scar nicely, and if the scar remains depressed, using a filler beneath it should complete the repair.  In the future you should take Valcyclovir at the first sign of a fever blister.
