Pilot Study Investigating the Efficacy of Fat Grafting as a Treatment for Male and Female Facial Acne Scarring

Pilot Study Investigating the Efficacy of Fat Grafting as a Treatment for Male and Female Facial Acne Scarring

This single-center, clinical trial consists of a one autologous fat grafting treatment followed by 3-month and 6-month post-treatment visits in order to assess the efficacy of fat grafting when used by men and women with facial acne scars.

This investigation, pilot study will evaluate the safety and efficacy of autologous fat grafting for the treatment of acne scarring. Overall assessment of clinical outcome and safety will be based clinic visits and evaluation of pre- and post- procedural photos. In conjunction with standard and close-up photography, we will also be using 3D imaging, cross-polarized imaging, UV imaging, high-resolution ultrasonography, optical coherence tomography, transepidermal water loss measurements, and/or BTC 2000 measurements. Additionally, we will be utilizing 0.33 mm skin biopsies to assess histological and genetic changes that occur below the skin surface as a result of this treatment. The subject's assessment of satisfaction will be characterized using a non-parametric assessment scale at each follow-up period.
