Daily Cosmetic Research Analysis
Safety in aesthetic medicine dominated today’s most impactful papers: a systematic review characterizes alopecia after cosmetic injections, and a cadaveric micro-CT study proposes an anatomically guided protocol for retrobulbar hyaluronidase in filler-induced visual loss. A network pharmacology–guided, multi-herb extract showed multi-target anti-acne activities, suggesting an evidence-based path for future cosmeceutical development.

Selected Articles
1. Alopecia Induced by Cosmetic Injection Procedures: A Comprehensive Review.
This review aggregates 25 reports (48 patients) of alopecia following cosmetic injection procedures, organizing data on materials, sites, timing, mechanisms, management, and outcomes. It emphasizes underreporting and the need for clinician awareness, prevention, and ready-to-implement treatment algorithms.
Impact: It consolidates scattered evidence of a rising but underrecognized complication, directly informing consent, risk mitigation, and early management in aesthetic practice.
Clinical Implications: Supports informed consent regarding rare alopecia risk, encourages injection techniques minimizing ischemia, and guides early recognition and treatment pathways for better hair salvage.
Key Findings
- Identified 25 publications describing 48 patients with alopecia after cosmetic injections.
- Synthesized data across filler types, injection/anatomic sites, onset, symptoms, proposed mechanisms, management, and outcomes.
- Highlights underreporting and calls for prevention and standardized management strategies.
Methodological Strengths
- Multi-database search (PubMed, Web of Science, Embase) with predefined selection criteria.
- Comprehensive extraction of clinical variables relevant to mechanism and management.
Limitations
- Evidence largely based on case reports/series with heterogeneous reporting.
- No meta-analysis or pooled effect estimates; risk factors and causality remain uncertain.
Future Directions: Establish prospective registries with standardized outcome reporting; develop consensus prevention and treatment algorithms and evaluate them in multicenter studies.
2. Anatomical Guideline for Retrobulbar Hyaluronidase Injection.
Cadaveric dissection plus micro-CT mapping defined a safe, standardized trajectory for retrobulbar hyaluronidase in filler-related central retinal artery occlusion: from inferolateral orbital rim toward superomedial quadrant using a 35 mm, 22–23G needle. The approach aims to avoid critical neurovascular structures and reduce globe injury risk.
Impact: Provides actionable, anatomy-based guidance for an emergency procedure to potentially reverse filler-induced visual loss, addressing a critical gap in standardized practice.
Clinical Implications: Supports training and protocolization of retrobulbar hyaluronidase use (trajectory, needle gauge/length) in multidisciplinary settings for filler emergencies.
Key Findings
- Inferolateral orbital approach minimizes risk to extraocular muscles and neurovascular structures.
- Optimal trajectory: from inferolateral orbital rim toward the superomedial quadrant.
- Recommended instrument: 35 mm length, 22–23G needle to reach retrobulbar space with reduced perforation risk.
Methodological Strengths
- Integration of cadaveric dissection with high-resolution micro-CT mapping.
- Focus on clinically relevant anatomic relationships for procedural safety.
Limitations
- Cadaveric study without clinical outcome validation.
- Anatomical variability and operator skill were not assessed in live scenarios.
Future Directions: Prospective evaluation of visual and perfusion outcomes after protocolized retrobulbar hyaluronidase; development of training simulations and decision algorithms.
3. Potential Cosmetic Applications of the Combined Extract of Panax ginseng, Ganoderma lucidum, Cordyceps militaris, and Several Asian Plants.
Using HPLC, network pharmacology, docking, and in vitro assays, a combined herbal extract (PGC) showed multi-target anti-acne effects: antibacterial activity against Cutibacterium acnes (MIC 25 μg/mL), barrier restoration (filaggrin +235%, loricrin +261%), reduced ROS and lipid accumulation, enhanced keratinocyte migration, and no cytotoxicity ≤200 μg/mL.
Impact: Demonstrates an evidence-based, network pharmacology–guided approach to formulate multitarget cosmeceuticals for acne, linking mechanistic predictions with functional assays.
Clinical Implications: Suggests a candidate multitarget topical ingredient for acne-prone skin; however, in vivo efficacy and safety data are needed before clinical or consumer use.
Key Findings
- Batch-consistent PGC contained phenolic acids, flavonoids, and alkaloids by HPLC.
- Network pharmacology/docking indicated IL-17/TNF/NF-κB axis modulation as a multitarget mechanism.
- Antibacterial activity against Cutibacterium acnes (MIC = 25 μg/mL) and barrier restoration (filaggrin +235%, loricrin +261%; 85% recovery from SDS damage).
- Reduced ROS (−45%), lipid droplets (−60%), and NO (−40%) with enhanced keratinocyte migration (+40%); no cytotoxicity ≤200 μg/mL.
Methodological Strengths
- Integration of HPLC characterization, in silico network pharmacology/docking, and multiple functional in vitro assays.
- Quantitative readouts across antimicrobial, barrier, oxidative stress, lipid, and inflammatory endpoints.
Limitations
- Preclinical in vitro study without animal or human validation.
- Complex multi-herb composition may face batch standardization and regulatory hurdles.
Future Directions: Conduct in vivo efficacy/toxicity studies, develop stable topical formulations, and progress to randomized clinical trials in acne.
