BACKGROUND: Worldwide, the use of soft tissue fillers for aesthetic purposes has significantly increased as have the number of associated complications. Vision loss is a rare but catastrophic complication of injecting tissue fillers. OBJECTIVES: We formed a UK multidisciplinary steering group in 2024 to develop consensus guidelines for the management of tissue filler-induced vision loss. METHODS: The multidisciplinary steering group consisted of various specialists with significant expertise in aesthetics, emergency ophthalmology, oculoplastic surgery and retina. Consensus statements were formulated by the group. RESULTS: Recommendations focussed on immediate emergency measures, access pathways to specialist care, improved consent processes, and increasing awareness of vision-related complications. CONCLUSIONS: These guidelines aim to provide pragmatic, evidence-based steps for frontline clinicians to optimise patient outcomes in this rare but devastating complication.
2. Clinical Evaluation of a Thiamidol-Based Regimen With SPF Compared With SPF Alone for Facial Hyperpigmentation.
In a randomized study of 95 adults with facial hyperpigmentation, a Thiamidol-based regimen plus SPF significantly outperformed SPF 30 alone by weeks 8 and 12 on skin lightness, ITA°, radiance, and shine, with improvements seen as early as week 2. Benefits persisted through a 6-week regression phase.
Impact: Provides randomized, objective evidence that adds to photoprotection in a step-up regimen for dyschromia, supporting integration of a human tyrosinase inhibitor into daily care.
Clinical Implications: Consider adding a Thiamidol-containing regimen to daily photoprotection for facial hyperpigmentation to accelerate and amplify improvements, with early benefits by week 2 and superiority by weeks 8–12.
Key Findings
- Randomized comparison of 95 participants: Thiamidol regimen (n=47) vs SPF 30 alone (n=48).
- Both groups improved from week 2; Thiamidol regimen was significantly superior at weeks 8 and 12 for skin lightness, ITA°, radiance, and shine.
- Improvements showed durability during a 6-week regression phase.
Methodological Strengths
- Randomized design with objective colorimetric endpoints (ITA°) and multi-timepoint assessments.
- Inclusion of a regression phase to assess durability of effect.
Limitations
- Blinding not described; single-center design may limit external validity.
- Majority of participants were Fitzpatrick I–III, potentially limiting generalizability to darker skin types.
Future Directions: Blinded, multi-center RCTs across diverse skin types; head-to-head comparisons with hydroquinone and other actives; longer-term maintenance and safety studies.
BACKGROUND: Hyperpigmentation disorders are common skin concerns that negatively impact patient quality of life and self-perception. Hyperpigmentation results from the overproduction of melanin via a multi-step process with a rate-limiting step catalyzed by tyrosinase. Thiamidol, an effective human tyrosinase inhibitor, has recently been shown to reduce visible signs of hyperpigmentation and could provide additional benefits when combined with the standard of care treatment for hyperpigmentation: photoprotection, specifically sunscreens with sun protection factor (SPF). METHODS: A randomized study was performed with 95 subjects (n=47, Thiamidol regimen; n=48, standard SPF 30 lotion) aged 18–65 clinically presenting with facial hyperpigmentation (measured by colorimeter and individual typology angle [ITA°]) to assess the efficacy of the Thiamidol-containing regimen (Day Lotion with SPF 30 and Serum applied in the morning, Night Cream and Serum applied in the evening) compared with a standard SPF 30 lotion for 12 weeks, followed by a 6-week regression phase. RESULTS: Facial hyperpigmentation, measured by skin lightness, ITA° values, radiance, and shine, was significantly reduced relative to baseline for both groups as early as week 2, and significantly reduced for patients receiving the Thiamidol-containing regimen vs the standard SPF 30 lotion at weeks 8 and 12. DISCUSSION: This study demonstrates that while SPF alone can reduce the visible signs of hyperpigmentation, the addition of Thiamidol to a daily skin care regimen confers additional, durable benefits with regard to skin lightness, radiance, and shine. CONCLUSION: These data support the integration of Thiamidol-containing formulations into existing skin regimens for individuals with facial hyperpigmentation.
3. Characterizing Safety Outcomes of a Dermal Filler: Injection Site and Timing Insights from the Maude Database.
Analysis of 315 MAUDE reports for Juvéderm Volbella found dermatologic and vascular events predominated, with higher vascular complication rates after perioral injections. Severe events presented later (median 75 vs 51 days) and perioral severe cases required antibiotics more often, supporting longer follow-up, enhanced consent, and site-specific risk stratification.
Impact: Provides real-world, site-specific safety signals and timing that can immediately refine protocols for high-risk perioral injections.
Clinical Implications: Adopt extended follow-up (2–3 months) after perioral Volbella injections, reinforce consent about delayed vascular risks, and tailor risk mitigation by injection site; prepare for higher likelihood of antibiotic use in severe perioral events.
Key Findings
- 315 adverse event reports analyzed (Jan 2020–Jan 2024) using standardized grading and statistical tests.
- Dermatologic and vascular events predominated; perioral injections had higher vascular complication rates.
- Severe AEs occurred later (median 75 days) than moderate AEs (51 days).
- Perioral severe cases required antibiotics in 53.3% vs 28.6% for mild cases (P=0.0003).
Methodological Strengths
- Use of a national device adverse event database with standardized grading.
- Site-based grouping and appropriate statistical tests (chi-square, Kruskal–Wallis).
Limitations
- Passive reporting subject to underreporting and reporting bias; lack of denominator prevents incidence estimation.
- Retrospective design limits causal inference; incomplete data in some reports.
Future Directions: Develop active surveillance/registries with denominators, validate site-specific risk mitigation protocols prospectively, and incorporate training for vascular complication recognition and delayed-onset monitoring.
BACKGROUND: Juvéderm Volbella distinguishes itself for being the only hyaluronic acid filler with dual FDA approval for perioral and infraorbital regions. Its Vycross technology formulation and use in high-risk vascular areas necessitate a comprehensive real-world safety analysis to inform clinical practice. OBJECTIVE: To evaluate and categorize adverse events associated with Juvéderm Volbella injections using the Manufacturer and User Facility Device Experience (MAUDE) database, focusing on injection sites and the number of treated areas. METHODS AND MATERIALS: Adverse event reports from January 2020 to January 2024 were reviewed and graded using standardized criteria. Events were grouped by injection site, number of anatomical areas injected, and time of symptom onset. Statistical analyses included chi-square and Kruskal-Wallis tests. RESULTS: Among 315 patients, dermatologic and vascular events predominated, with higher vascular complication rates following perioral injections. Severe adverse events (CTCAE >2) occurred at a median of 75 days postinjection versus 51 days for moderate events. Perioral injections required antibiotics in 53.3% of severe cases versus 28.6% of mild cases (P=0.0003). CONCLUSION: Perioral Volbella injections demonstrate increased vascular complication risks requiring modified clinical protocols: extended follow-up schedules (2-3 months versus standard 2 weeks), enhanced informed consent, and site-specific risk stratification. These findings provide immediate, actionable evidence for improving patient safety through evidence-based practice modifications.
