Quantifying the variations in thickness and echogenicity that occur in different facial layers due to the senescence process is challenging. This study aimed to verify the changes in the ultrasound pattern after three sessions of facial adipostructuring using high-frequency ultrasound. This was a prospective, longitudinal, observational study of a 42-year-old female patient, selected based on specific clinical criteria for facial rejuvenation treatment. Ultrasound images were acquired using a 16-20 MHz multifrequency high-resolution ultrasound scanner (Clarius L20, Clarius Mobile Health, British Columbia, Canada) at two facial sites: the superficial adipose compartment of the malar and nasolabial regions, before and after three sessions of facial adipostructuring. Among the most relevant ultrasound findings after applying the adipostructuring sessions, the nasolabial panniculus showed a sonographic modification in the arrangement pattern, specifically in the subcutaneous cellular tissue. This included an improvement in the connective tissue fibers that support all the adipose cells. The malar panniculus showed a slight thickening, increasing from 1.5 to 1.7 millimeters in thickness. In conclusion, the synergy between high-resolution ultrasound and facial adipostructuring establishes a new standard in aesthetic medicine and facial harmonization, where precision, safety, and objective evaluation replace the empirical approach. It not only acts as an intraoperative map but also as a scientific validation tool that allows for the quantification and statistical demonstration of the benefits of facial rejuvenation, elevating adipostructuring to an intervention rigorously based on evidence.
