1. Effects of periocular botulinum toxin injection on ocular surface parameters and pupillary dynamics: a prospective clinical study.
Periocular botulinum toxin injections significantly reduced TBUT and Schirmer values at 20 days and altered pupillary dynamics, including increased minimum and mesopic pupil diameters and faster constriction velocity. The data support combined mechanical and neuro-autonomic effects and underscore ocular surface and autonomic safety considerations in cosmetic applications.
Impact: This study provides prospective, quantitative evidence of ocular surface compromise and neuro-autonomic effects after cosmetic periocular botulinum toxin, a widely used procedure with limited objective safety data.
Clinical Implications: Screen for dry eye risk factors, counsel on transient ocular surface deterioration, and consider supportive measures (lubricants, dose/placement adjustments) in susceptible patients. Be mindful of mesopic vision changes in activities requiring low-light performance.
Key Findings
- TBUT and Schirmer test values decreased significantly post-injection (P < 0.001), indicating ocular surface deterioration.
- Minimum and mesopic pupil diameters increased significantly (P = 0.001 and P = 0.046, respectively), while maximum and photopic diameters did not.
- Pupil constriction velocity increased significantly (P = 0.030); dilation velocity trended upward without significance (P = 0.107).
Methodological Strengths
- Prospective interventional, within-subject design with standardized measurements
- Use of generalized estimating equations to account for inter-eye correlation and objective pupillometry
Limitations
- Small sample size (13 patients) and short (20-day) follow-up
- Lack of a control/sham group limits causal inference and generalizability
Future Directions: Conduct larger controlled studies with longer follow-up, stratifying by dose and injection sites, and integrate comprehensive ocular surface and autonomic testing to delineate mechanisms.
PURPOSE: To evaluate the effects of periocular botulinum toxin injection on ocular surface parameters and pupillary dynamics, and to explore its potential neuro-autonomic implications. METHODS: In this prospective interventional study, 26 eyes from 13 patients undergoing cosmetic periocular botulinum toxin injection were evaluated. Ocular surface parameters, including tear breakup time (TBUT) and Schirmer test, and pupillometric measurements (dynamic and static) were assessed before injection and at 20 days post-treatment under standardized conditions. RESULTS: Following botulinum toxin injection, both TBUT and Schirmer test values decreased significantly (P < 0.001 for both), indicating deterioration of ocular surface function. Dynamic pupillometry revealed a significant increase in minimum pupil diameter (P = 0.001), while maximum pupil diameter showed a non-significant change (P = 0.318). Mesopic pupil diameter increased significantly (P = 0.046), whereas photopic pupil diameter did not reach significance (P = 0.557). Notably, pupil constriction velocity increased significantly (P = 0.030), suggesting enhanced pupillary responsiveness, while dilation velocity increased but did not reach statistical significance (P = 0.107). All analyses were performed using generalized estimating equations to account for inter-eye correlation. CONCLUSION: Periocular botulinum toxin injection was associated with significant deterioration in ocular surface parameters and measurable alterations in pupillary dynamics, including increases in minimum and mesopic pupil diameters and constriction velocity, supporting combined mechanical and neuro-autonomic effects. These findings highlight the importance of considering both ocular surface and autonomic effects when evaluating the safety profile of cosmetic botulinum toxin applications.
2. Protective Effects of an Advanced Antioxidant Serum and an Encapsulated Vitamin C Serum From UV-Induced Erythema and Oxidative Stress.
In a randomized controlled trial of 15 women, pretreatment with an advanced antioxidant serum significantly reduced UV-induced erythema and improved biomarker profiles of cellular protection compared with an encapsulated vitamin C serum and untreated irradiated skin. Findings support enhanced photoprotection beyond sunscreen through antioxidant serums.
Impact: Provides controlled clinical evidence comparing two commonly used antioxidant strategies, showing superior outcomes with an advanced serum on both clinical (erythema) and molecular endpoints.
Clinical Implications: Supports incorporating advanced antioxidant serums as adjuncts to photoprotection regimens, particularly before UV exposure, while emphasizing the need to maintain sunscreen as standard of care.
Key Findings
- Pretreatment with the advanced antioxidant serum significantly reduced UV-induced erythema at 1× MED compared with encapsulated vitamin C serum and untreated/irradiated skin.
- Biomarker analysis indicated significantly greater cellular protection with the advanced serum versus comparators.
- Study population was limited to healthy adults with limited Fitzpatrick diversity, noted by authors as a limitation.
Methodological Strengths
- Randomized controlled design assessing both clinical erythema and molecular biomarkers
- Standardized test sites and dosing on each participant to reduce inter-individual variability
Limitations
- Small sample size (n=15) and conducted in healthy adults only
- Limited representation across Fitzpatrick skin types and use of lower back skin rather than facial skin
Future Directions: Larger, blinded trials across diverse skin phototypes and anatomical sites, with standardized biomarker panels and real-world UV exposure paradigms.
OBJECTIVE: To evaluate the protective effects of 2 antioxidant products against UV light by assessing UV-induced erythema and skin damage biomarkers. METHODS: A randomized, controlled trial enrolled 15 healthy women aged 35 to 60 years. Participants' lower backs were marked with 4 test sites (5 cm × 6 cm). Test products (4 mg/cm RESULTS: Pretreatment with the advanced antioxidant serum (TAP) demonstrated 72% (1× MED, LIMITATIONS: This study was conducted in healthy participants (mean age: 49 years), with limited representation across Fitzpatrick skin types. Future studies should include a more diverse study population. CONCLUSION: Pretreatment with TAP demonstrated significantly less UV-induced erythema and provided significantly greater cellular protection vs Encap-C serum and untreated/irradiated skin.
3. Hyperbaric Oxygen Therapy in the Management of Dermal Filler-Induced Vascular Occlusion: A Scoping Review.
This PRISMA-ScR–conformant scoping review synthesized 24 reports on HBOT as an adjunct for filler-induced vascular occlusion. Protocols varied (2.0–3.0 ATA, 60–120 minutes), outcomes were heterogeneous and confounded by multimodal therapy, underscoring the need for standardized pathways and prospective evaluation.
Impact: First comprehensive mapping of HBOT use specifically for filler-induced vascular occlusion, informing clinicians about real-world parameters and highlighting critical evidence gaps for this rare but severe aesthetic complication.
Clinical Implications: HBOT may be considered as an adjunct in select FIVO cases after immediate standard care (e.g., hyaluronidase), ideally within multidisciplinary protocols. Clinicians should align with evolving standardized pathways and contribute to prospective data collection.
Key Findings
- Twenty-four studies (mostly case reports/series) reported HBOT as adjunctive to established FIVO therapies.
- HBOT parameters varied widely (2.0–3.0 ATA; 60–120-minute sessions; variable session counts), reflecting lack of standardized protocols.
- Outcomes were heterogeneous and often confounded by multimodal interventions, indicating low-certainty evidence.
Methodological Strengths
- Adherence to PRISMA-ScR guidelines with multi-database search
- Broad inclusion capturing real-world practice patterns across languages (English/Spanish)
Limitations
- Evidence base dominated by case reports/series with high risk of bias
- Marked heterogeneity of HBOT protocols and concomitant treatments precluding meta-analysis
Future Directions: Develop consensus protocols (timing, pressure, duration, session number) and conduct prospective registries or controlled studies to evaluate HBOT’s incremental benefit over standard FIVO care.
BACKGROUND: Hyperbaric oxygen therapy (HBOT) has been used in ischemic and inflammatory conditions due to its ability to enhance tissue oxygenation and support wound healing. Filler-induced vascular occlusion (FIVO) is a rare but potentially devastating complication of dermal filler injections that may result in skin necrosis or vision loss. HBOT has been increasingly reported as an adjunctive intervention in FIVO, but its reported use has not been systematically summarized. OBJECTIVE: To summarize the existing literature on HBOT use in FIVO, describe reported clinical contexts and treatment parameters, and identify gaps in current knowledge. METHODS: This scoping review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. A comprehensive search of PubMed, MEDLINE, Embase, and Google Scholar identified case reports, case series, experimental studies, and reviews describing FIVO cases managed with HBOT. Articles published in English or Spanish between January 2011 and May 2025 were included. Data were synthesized descriptively. RESULTS: Twenty-four studies met inclusion criteria, consisting primarily of case reports and small case series. HBOT was most often used as an adjunct to established therapies, including hyaluronidase, antiplatelet agents, vasodilators, and thrombolytic therapy. Reported HBOT protocols varied substantially, with treatment pressures of 2.0 to 3.0 atmospheres absolute and session durations of 60 to 120 minutes. Outcomes were heterogeneous and frequently confounded by multimodal management. CONCLUSION: HBOT has been reported as an adjunctive intervention in selected cases of FIVO, but evidence remains limited to low-level observational data, highlighting the need for standardized protocols and prospective studies.
