Complications, Treatment, and Outcomes of Self-Injecting Substances Into the Face: A Systematic Review

Abstract

Background: The increased demand for minimally invasive facial cosmetic procedures in tandem with the ease of acquiring injectable cosmetics through direct-to-consumer retailers has led to a rise in self-injecting cosmetics among untrained individuals.

Objective: To analyze complications, treatments, and outcomes associated with self-injecting fillers into the face.

Methods: A systematic review of the literature from PubMed and Embase databases was performed from inception to September 10, 2022, to identify studies pertaining to self-injection of facial fillers.

Results: A total of 15 articles describing 38 complications among 18 patients were included in the data collection. The most commonly injected substance was hyaluronic acid (76.4%). The lips were the most common site of injection (33%). The most reported complication was edema (61%). Severe complications included acute vascular compromise (11%) and acute hearing loss (5%). The most common intervention was use of hyaluronidase and/or antibiotics (87.5%). Patients generally healed after treatment although residual localized hyperpigmentation was noted among 11% of patients.

Conclusion: Injecting commercially available substances into the face is associated with potentially irreversible aesthetic, infectious, and vascular complications, especially in the hands of untrained consumers. Patients and providers should be aware of this dangerous trend.
