Cosmetic face fillers: A warning and new insights into potential risks
Cosmetic fillers, a popular choice for those seeking to smooth wrinkles and enhance their appearance, may come with a hidden danger. Experts are now urging caution, revealing a potentially life-threatening complication linked to these injections. The issue? Blocked arteries, which can lead to skin loss, blindness, and severe tissue damage.
A recent study, conducted by Dr. Rosa Sigrist and her team from the University of São Paulo, Brazil, sheds light on this critical concern. The research, presented at the Radiological Society of North America's annual conference, analyzed 100 cases of filler injections gone awry. Using ultrasound technology, the team uncovered alarming details.
In nearly half of the cases, ultrasound scans detected absent blood flow in small blood vessels connecting superficial and deep facial arteries. Even more concerning, a third of the cases involved major blood vessels with no blood flow.
Dr. Sigrist emphasizes the severity of these 'vascular occlusion' events, where fillers are injected into or too close to blood vessels. Such incidents can be devastating, causing tissue death and facial deformity if not promptly treated. This highlights the importance of ultrasound guidance during filler injections.
The study recommends that clinics utilize ultrasound to plan injection sites, reducing the risk of complications. If issues arise, ultrasound can guide precise treatment. Dr. Sigrist explains, "Without ultrasound guidance, injectors may treat based on clinical findings, injecting blindly. But with ultrasound, we can pinpoint the exact location of occlusion."
Instead of flooding the area with hyaluronidase to dissolve the filler, guided injections using less hyaluronidase can provide better outcomes. This approach is gaining traction, with the British Association of Aesthetic Plastic Surgeons (BAAPS) noting an increase in ultrasound usage.
BAAPS President Nora Nugent emphasizes the benefits of ultrasound, stating, "Mapping blood vessel locations is invaluable before treatment. These risks from dermal fillers underscore our long-standing advocacy for stricter regulation of aesthetic procedures and restricting injectable treatments to medically trained professionals."
The UK government has responded to these concerns by proposing restrictions on cosmetic procedures. Under these plans, only qualified healthcare professionals would be authorized to perform high-risk procedures like Brazilian butt lifts. Clinics administering fillers and Botox would need to meet stringent standards for licensing.
A public consultation is scheduled for early 2026, inviting input on the procedures to be covered by the new restrictions. The decision will then be made by Parliament, marking a significant step towards ensuring patient safety in the cosmetic industry.
