Scar Treatment

What Is It?

Augmentation uses temporary, semi-permanent, or permanent dermal fillers that replace volume of soft tissue that is lost. All fillers also stimulate collagen production, which helps build up the skin, thus evening the skin’s surface.

Good or Excellent Response

Strength of Evidence
66% of patients achieved a good (>50%) or excellent (>75%) improvement in scarring after 1 - 4 sessions

Moderate Response

Strength of Evidence
72% of patients achieved at least a moderate (>25%) improvement in scarring after 1 - 4 sessions
