Summary
Three impactful studies shape cosmetic and aesthetic medicine today: a nonhuman primate model demonstrates that intra-arterial hyaluronidase can partially restore vision after hyaluronic acid filler-induced ophthalmic artery embolism within a 24-hour window; a systematic review indicates adipose tissue browning promotes fat graft retention via angiogenesis and inflammation reduction; and a mixed-methods global synthesis quantifies non-surgical aesthetic treatment complications and prioritizes safety surveillance.
Research Themes
- Safety surveillance and risk stratification in non-surgical aesthetic treatments
- Mechanistic and translational models for filler-induced vascular occlusion and rescue
- Biological augmentation of fat graft retention via adipose browning

1. Nonhuman Primate Model of Super-selective Intra-arterial Ophthalmic Arterial Interventional Thrombolysis for Treatment of Ophthalmic Arterial Embolism Resulting From Hyaluronic Acid Filler Cosmetic Injection.
A rhesus monkey model of ophthalmic artery embolism from HA filler was established and reperfused via super-selective intra-arterial hyaluronidase thrombolysis. Recanalization at 1, 4, or even 24 hours improved visual function but residual dysfunction and retinal injury persisted; single-cell RNA-seq showed decreased rhodopsin expression with longer ischemia.
Impact: This translational primate model fills an evidence gap for managing filler-induced blindness and suggests a clinically meaningful treatment window for intra-arterial hyaluronidase.
Clinical Implications: Supports considering super-selective intra-arterial hyaluronidase thrombolysis within up to 24 hours after HA filler-related ophthalmic artery embolism, while counseling patients about residual deficits.
Key Findings
- Established a rhesus monkey model of ophthalmic artery embolization by intra-arterial HA injection and achieved reperfusion via intra-arterial hyaluronidase.
- Recanalization at 1, 4, and 24 hours improved visual function, though some dysfunction persisted on electroretinography.
- Histology confirmed retinal cellular damage post-embolization; scRNA-seq revealed decreased rhodopsin expression with longer ischemia time.
Methodological Strengths
- Translational nonhuman primate model closely simulating clinical OA ischemia-reperfusion.
- Multimodal assessment (DSA, fluorescein angiography, ERG, histology/TEM, scRNA-seq) across defined time windows.
Limitations
- Preclinical animal study with unspecified sample size; no randomized comparator or dose-finding.
- Residual functional impairment despite reperfusion; long-term outcomes not assessed.
Future Directions: Prospective clinical registries and controlled trials to define optimal dosing, timing, and adjuncts for intra-arterial hyaluronidase; validation of molecular markers as prognostic indicators.
2. Enhancing fat graft retention through adipose tissue browning: a systematic review.
Across 14 studies, adipose browning emerged around day 7 post-grafting, stabilized by ~3 months, and sometimes reverted to white adipose tissue. Browning enhanced graft retention through early angiogenesis, reduced inflammation, and increased adipogenesis; the cellular origin of beige adipocytes remains unresolved.
Impact: Synthesizes mechanistic and temporal evidence that browning improves fat graft survival, informing biological augmentation strategies in aesthetic and reconstructive surgery.
Clinical Implications: Suggests that inducing browning (e.g., using beige fat or pro-browning stimuli) and optimizing the early post-graft window may improve retention and outcomes in fat grafting.
Key Findings
- Browning appears peripherally in grafts around day 7, stabilizes by ~3 months, and may later revert to white adipose phenotype.
- Browning enhances retention via early angiogenesis, inflammation reduction, and upregulated adipogenesis.
- Evidence base comprises 13 animal studies and 1 clinical report; cellular origin of beige adipocytes remains unclear.
Methodological Strengths
- Systematic, multi-database search with explicit inclusion/exclusion criteria.
- Integration of temporal dynamics and mechanistic pathways across studies.
Limitations
- Predominantly preclinical animal data and one clinical report; heterogeneity precluded meta-analysis.
- Lack of standardized outcome measures and limited long-term clinical data.
Future Directions: Prospective clinical trials to test pro-browning strategies (e.g., beige fat grafting, pharmacologic inducers), standardized endpoints, and lineage-tracing studies to define beige adipocyte origins.
3. Decades of Scientific Data and Global Media Reporting on Complications in Non-surgical Aesthetic Treatments for a Transparent Safety Profile: Kissing Snow White Awake.
In a mixed-methods synthesis of 231,475 documented complications, dermal fillers accounted for 42% (granulomas, vascular occlusions, delayed hypersensitivity), botulinum toxin A for 15% (mostly mild), and thread lifts showed frequent extrusion and infection. Products with >85% safety probability were identified, and geospatial analyses highlighted disproportionate risks in Asia, with unregulated therapies (e.g., exosomes) flagged as emerging hazards.
Impact: Provides a comprehensive, data-driven safety profile for NSATs, integrating scientific and real-world signals to guide regulation, credentialing, and patient counseling.
Clinical Implications: Supports standardized complication reporting, adoption of ultrasound-guided techniques, and avoidance of unregulated biologics; informs risk communication and device/product selection.
Key Findings
- Dermal fillers were responsible for 42% of complications; botulinum toxin A for 15%, with thread lifts showing frequent extrusion and infection.
- Identified products/procedures with >85% safety probability (e.g., Prabotulinumtoxin A, Juvéderm high-viscosity fillers, Profhilo, APTOS Light Lift, microneedling RF, Ultherapy, EMFACE).
- Geospatial analysis showed 34% of complications reported in Asia; machine learning flagged unregulated therapies (e.g., exosomes) as emerging risks.
Methodological Strengths
- Large-scale, multi-source dataset with advanced statistical and machine learning methods and geospatial mapping.
- Sensitivity analyses to address potential reporting biases.
Limitations
- Heterogeneity and potential bias from media/social sources; not a PRISMA-compliant systematic review.
- Causality cannot be established; underreporting and variable definitions likely.
Future Directions: Implement mandatory adverse event registries, harmonize global regulations, and develop AI-driven real-time surveillance; prospective comparative safety studies of products and techniques.
