Researchers have recently issued a warning regarding complications that may arise from dermal fillers, with potential risks including blindness. The research has brought to light the dangers associated with vascular occlusion, which can lead to skin injury, necrosis, and in extreme cases, even blindness. This serious complication occurs when the filler material either enters a blood vessel or compresses it, thereby hindering or entirely blocking blood flow to the surrounding skin or tissue. The implications of these findings are significant, urging caution and awareness among those considering dermal filler treatments.

Lead researcher Dr. Rosa Sigrist from the University of São Paulo in Brazil spearheaded a study examining “vascular occlusion events” in 100 patients across various medical centres internationally. The research spanned from May 2022 to April 2025 and revealed the grave consequences of vascular occlusion. Board-certified plastic surgeon Dr. Bob Basu emphasized the critical nature of this complication, highlighting the necessity for well-trained professionals to administer dermal fillers. The risks associated with vascular occlusion underscore the importance of seeking expert guidance and medical advice before undergoing cosmetic procedures.
Dr. Sigrist’s research emphasised the significance of clinics utilising ultrasounds prior to administering dermal fillers, in a bid to avoid vascular occlusion incidents. By proactively identifying potential blood vessels, injectors can navigate the filler material more safely, thus reducing the risk of adverse effects. Despite these recommendations, Dr. Basu suggests that mandatory ultrasound may not be the ultimate solution. He advocates for the importance of skilled injectors, such as board-certified plastic surgeons and dermatologists, who possess a deep understanding of facial anatomy and are adept at addressing rare complications promptly.
In the event of vascular occlusion occurring, swift and appropriate action is crucial in mitigating its impact. Trained injectors are equipped to identify and respond to such complications effectively. Treatment methods typically involve dissolving the filler with hyaluronidase, applying warm compresses, enhancing blood flow, and closely monitoring the affected area. While dermal fillers are generally considered safe, patients should be fully informed of the potential risks involved. Dr. Basu stresses the importance of early recognition and appropriate management to prevent complications from escalating.
Dr. Shim Ching, a plastic surgeon and founder of Asia Pacific Plastic Surgery, advises individuals to engage in open dialogue with their injectors regarding the possibility of vascular occlusion. Being proactive and discussing preventative measures can help individuals make informed decisions about their cosmetic treatments. Certain facial areas are more susceptible to vascular occlusion due to their vascular structure, necessitating caution and precision during filler injections. Dr. Basu notes that experienced injectors may opt for alternative techniques, such as blunt cannulas or minimal filler volumes, to minimise risks in vulnerable areas.
In light of the elevated risks associated with dermal fillers, it is imperative for individuals to approach cosmetic procedures with caution and awareness. Seeking out certified and experienced practitioners is essential in ensuring safe and successful outcomes. By prioritising safety and thorough risk assessment, patients can navigate the realm of cosmetic enhancements with confidence and peace of mind. As the field of cosmetic procedures continues to evolve, staying informed and vigilant about potential complications remains paramount for both practitioners and patients alike.
