1. Treatment of Acquired Dermal Macular Hyperpigmentation With Oral Isotretinoin: A Multi-Institutional Retrospective Study of 121 Cases.
In a multicenter retrospective cohort (n=121), oral isotretinoin (commonly 20 mg/day for ~8 months) improved ADMH, with all Riehl’s melanosis and 90.4% of lichen planus pigmentosus patients showing improvement. Marked response was more frequent in RM (63.0%) than LPP (33.0%), and better outcomes associated with localized disease, shorter duration (<5 years), Fitzpatrick III–VI, and longer treatment.
Impact: This is the largest multi-institutional dataset evaluating isotretinoin for ADMH, identifying response predictors and providing actionable dosing/duration insights.
Clinical Implications: Consider off-label isotretinoin for refractory ADMH, especially in Riehl’s melanosis and localized, shorter-duration disease; anticipate better outcomes with longer courses and Fitzpatrick III–VI. Monitor for isotretinoin adverse effects and counsel patients on realistic timelines.
Key Findings
- Improvement in all RM and 90.4% of LPP cases; marked improvement in 63.0% (RM) and 33.0% (LPP).
- Better response with localized lesions (p=0.0012), disease duration <5 years (RM p=0.046; LPP p=0.0272), Fitzpatrick III–VI (p=0.0081), and longer treatment (p=0.0178).
- Most patients received 20 mg/day for an average of 8 months; RM responded better than LPP (p=0.005).
Methodological Strengths
- Multicenter, international cohort (121 patients) with standardized IGA assessment.
- Predefined subgroup analyses with statistical significance reporting.
Limitations
- Retrospective design without a control group limits causal inference.
- Heterogeneity in dosing and incomplete safety detail in the abstract.
Future Directions: Prospective controlled trials comparing isotretinoin with standard therapies, dose–response optimization, safety profiling, and biomarker-driven patient selection.
2. Skinspan: A Holistic Roadmap for Extending Skin Longevity With Evidence-Based Interventions.
This comprehensive review introduces the "skinspan" framework and synthesizes molecular hallmarks of skin aging with graded evidence for interventions. It recommends first-line preventive measures (sun protection, topical retinoids, antioxidants), second-line device-based procedures, and considers emerging therapies as adjuncts pending stronger evidence.
Impact: It reframes aesthetic dermatology toward prevention and long-term skin health with an evidence-prioritized algorithm that can standardize consultations and care plans.
Clinical Implications: Adopt a prevention-first regimen for skin aging: daily photoprotection plus topical retinoids and antioxidants, escalating to energy-based devices as needed; reserve stem cell/sirtuin/nicotinamide-based approaches as adjuncts until supported by RCTs.
Key Findings
- Defines "skinspan" and aligns interventions with molecular hallmarks of aging (genomic instability, mitochondrial dysfunction, cellular senescence, proteostasis decline).
- First-line: photoprotection, topical retinoids, antioxidants; second-line: lasers/energy-based devices; third-line adjuncts: stem cell-based therapies, sirtuins, nicotinamide, natural SIRT activators.
- Calls for more randomized controlled trials to strengthen the evidence base for emerging therapies.
Methodological Strengths
- Integrates molecular geroscience with clinical interventions into a practical algorithm.
- Evidence grading across lifestyle, topical, systemic, and device-based modalities.
Limitations
- Narrative comprehensive review rather than a PRISMA-compliant systematic review.
- Heterogeneous evidence quality; limited RCT data for emerging modalities.
Future Directions: Randomized controlled trials testing preventive regimens, standardized outcome measures for "skinspan," and head-to-head comparisons of device-based and pharmacologic strategies.
3. Late complication of cosmetic injectable treatments presenting to oral and maxillofacial surgeons: soft tissue filler granulomas.
A case of trismus caused by intramasseteric granulomas after soft-tissue filler injections highlights a serious late-onset complication. The report emphasizes increasing complication rates, the role of oral and maxillofacial surgeons, and the need for collaboration with aesthetic clinicians in a largely unregulated treatment landscape.
Impact: Raises awareness of an uncommon but potentially debilitating filler complication, informing referral pathways and multidisciplinary management.
Clinical Implications: Clinicians should consider intramasseteric granuloma in patients presenting with trismus after fillers, expedite referral to oral and maxillofacial surgery, and establish collaborative management protocols.
Key Findings
- Reports trismus due to intramasseteric granulomas following soft-tissue filler injections.
- Highlights rising rates of complications after cosmetic treatments and the delayed-onset nature of granulomas.
- Stresses the need for collaboration between surgeons and aesthetic medicine clinicians amid limited regulation.
Methodological Strengths
- Clear clinical description of a rare, function-limiting complication.
- Contextualization within broader trends of increasing cosmetic treatment complications.
Limitations
- Single case report limits generalizability and cannot establish causality.
- Management details and long-term outcomes are not provided in the abstract.
Future Directions: Develop registries for filler complications, define imaging and treatment algorithms, and advance regulation and training standards for injectables.
