    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.
