Improvement in Early Scar Maturation by Nanofat Infiltration: Histological and Spectrophotometric Preliminary Results From a Split Scar-Controlled, Randomized, Double-Blinded Clinical Trial.

Background: The regenerative properties of stromal vascular fraction (SVF) in wound healing and scar formation are a subject of increasing clinical interest.

Objectives: Although preclinical studies have confirmed the angiogenetic, proliferative, and antifibrotic properties of SVF, there is limited clinical evidence from randomized controlled clinical trials.

Methods: Twelve patients who underwent abdominoplasty were included in this clinical study.

Spreading Pattern and Tissue Response to Hyaluronic Acid Gel Injections in the Subcutis: Ultrasound Videos, Ultrasound Measurements, and Histology.

Background: Despite the popularity of hyaluronic acid (HA) filler treatments, few publications focus on their effects on adipose tissue.

Objectives: The authors assessed the deposition pattern in the subcutis of injected HA, the tissue response at short and intermediate term, and the effects of remodeling the filler by strong finger pressure immediately after the treatment.

Methods: Two brands, specifically developed by the industry for deep injection, were compared.
