Hyaluronic Acid Fillers: 3D Scans Reveal Long-term Effects on Facial volume
Table of Contents
New research utilizing 3D digital scans provides detailed insights into the impact of hyaluronic acid (HA) fillers on restoring facial volume and fullness. The study, published in Plastic and Reconstructive Surgery®, offers a thorough understanding of both immediate and long-term results.
What are Hyaluronic Acid (HA) Fillers?
Injectable dermal fillers are a popular non-surgical option for individuals seeking a more youthful appearance. They effectively reduce facial lines and wrinkles and restore volume lost due to aging. Hyaluronic acid (HA) products are the most commonly used fillers, with over 5.3 million procedures performed in 2024 according to the American Society of Plastic Surgeons (ASPS).
The Study: Methodology and Findings
Researchers lead by Dr. Ivona Percec at the University of Pennsylvania addressed gaps in existing research by evaluating both objective and subjective outcomes of HA filler injections. They employed advanced three-dimensional scanning technology (Vectra M3 imaging system) to precisely measure changes in tissue volume. Patient-reported outcomes, including facial appearance and quality of life, were assessed using the validated FACE-Q questionnaire.
the study involved 101 women aged 40 to 65 who underwent HA filler injections for facial rejuvenation. Three diffrent HA filler formulations were used across various facial areas. 3D scans were taken immediately before and after treatment, and again at two to 12 weeks post-treatment to track volumetric changes in eight key facial regions.
Key Findings & Data
While specific data points from the study are not fully available in the provided text, the research highlights the importance of combining objective measurements with patient perceptions to understand the full impact of HA fillers. The use of 3D scanning allows for a more precise assessment of volumetric changes than conventional methods.
