Abstract
- Background.
- Non-surgical facial aesthetic procedures are among the fastest-growing interventions worldwide, yet rates of adverse events vary widely between providers and jurisdictions.
- Methods.
- PubMed, Embase and Cochrane databases were searched (2010–2025) for studies reporting safety outcomes of botulinum toxin and dermal filler procedures performed in non-hospital settings.
- Results.
- Adverse event rates ranged from 0.05% for minor injection-site reactions to 0.001% for vascular occlusion events. Rates were significantly lower in regulated, clinician-led settings.
- Conclusion.
- Patient safety in non-surgical aesthetics is closely linked to operator training, regulatory environment and structured complication-management protocols.
Keywords: patient safety, non-surgical aesthetics, dermal fillers, botulinum toxin, complications, regulation
1. Introduction
The expansion of non-surgical aesthetics has outpaced regulatory frameworks in many jurisdictions, exposing patients to variable standards of care.
2. Methods
A PRISMA-guided search identified 47 eligible studies. Outcomes of interest included infection, nodule formation, vascular occlusion and patient-reported satisfaction.
3. Results
Vascular occlusion remained the most clinically significant adverse event, with reported incidences of 0.001–0.05% per millilitre injected.
4. Discussion
Lower adverse event rates were consistently reported in studies originating from regulated, clinician-led settings, supporting calls for tighter UK regulation.
5. Conclusion
Standardised training pathways, mandatory complication protocols and registration of practitioners are likely to reduce harm.
