While Botox does not treat acne scarring dermal fillers are sometimes useful. Botulinum toxin works by weakening muscle contraction whereas acne scarring results from the skin being scarred down to deeper structures. In some cases, combined subcision and treatment with dermal fillers can temporarily fill in the "divot" resulting from acne scarring.Stephen Weber MD, FACS
Botox doesn't do anything for acne scarring. See your cosmetic surgeon for all the various methods of scar revisions.
