Retrospective Analysis of 2227 Restylane Filler Treatments in a UK Training Academy

Abstract

Background:

Injectable hyaluronic acid (HA) fillers, particularly the Restylane (Galderma Laboratories, LP) range, are widely used in cosmetic treatments, yet comprehensive data on adverse events in training academy settings remain sparse. This retrospective study aims to evaluate the incidence and nature of adverse events associated with Restylane fillers across 2227 treatments of 1052 patients conducted at a leading U.K. training academy.

Methods:

We conducted a detailed analysis of treatment records from August 2020 to July 2023, examining the frequency and types of adverse events in relation to different Restylane products and treatment areas.

Results:

Among the 2227 treatments, a total of 6 adverse events were documented, yielding an adverse event rate of 0.269%. The most common adverse events included bruising and asymmetry, with the tear trough and lips being the most frequently affected areas. No serious adverse events were reported.

Conclusion:

This study demonstrates a relatively low incidence of adverse events in HA filler treatments within a training academy setting, reporting a low complication rate. Further studies are recommended to expand upon these findings and explore long-term outcomes.
