1. CRISPR-Cas9 editing of agricultural crops and medicinal plants: toward a cornucopia of natural products.
This review synthesizes advances in applying CRISPR/Cas9 to medicinal plants and crops to rewire metabolic pathways and boost yields of bioactive natural products relevant to pharmaceutical, cosmetic, and nutraceutical sectors. It highlights strategies to overcome low-yield and sustainability barriers by pathway modulation to improve identification, development, and commercialization of plant-derived actives.
Impact: Genome editing offers a scalable, sustainable route to supply constrained cosmetic actives and enables discovery through pathway engineering. This could reshape ingredient pipelines and reduce reliance on endangered or slow-growing plants.
Clinical Implications: For dermatology and cosmetic science, engineered plant sources could stabilize availability and quality of actives (e.g., antioxidants, pigmentation modulators), supporting consistent efficacy and safety profiles in formulations.
Key Findings
- CRISPR/Cas9 has been successfully used to engineer medicinal plants and crops to modulate biosynthetic pathways of high-value metabolites.
- Genome editing addresses low-yield and sustainability issues of plant actives derived from slow-growing or endangered species.
- Pathway engineering accelerates natural product identification, development, and commercial viability for pharmaceutical, cosmetic, and nutraceutical applications.
Methodological Strengths
- Comprehensive cross-sector review integrating medicinal plants, food, and commercial crops
- Focus on mechanistic pathway modulation with concrete application examples
Limitations
- Narrative review without PRISMA-based systematic methods or quantitative synthesis
- Potential publication bias toward successful CRISPR applications
Future Directions: Prospective comparative studies of edited vs. wild-type lines, multi-omics validation of pathway rewiring, scalable bioprocess development, and regulatory frameworks for cosmetic ingredient approval.
Plants have been a part of human health since our very beginnings, and many of our modern pharmaceuticals claim their origins from medicinal plants. The range of specialized metabolites synthesized by plants is highly diverse, and metabolic functions have developed over the millennia to cover roles such as defense, adaptation to environmental stress, and even reproduction. These metabolites subsequently play roles in human health and diseases that are both significant and profound. The importance of pl
2. Coumarins and the science of timeless beauty: A natural anti-skin aging solution.
Integrating traditional and modern evidence, this review outlines how coumarins counter skin aging via antioxidant and anti-inflammatory actions, MMP inhibition, and modulation of sirtuin/AMPK pathways. It also discusses safety, formulation experiences (e.g., with hyaluronic acid), and sustainability considerations relevant to next-generation cosmetic development.
Impact: Coumarins offer multi-target, dermo-compatible mechanisms that align with demand for natural, effective anti-aging actives, potentially reducing adverse effects compared with some synthetics.
Clinical Implications: Formulators can prioritize coumarin-rich botanicals as anti-aging actives targeting oxidative stress and collagen degradation, while monitoring regulatory limits and conducting dermatologic safety testing.
Key Findings
- Coumarins exert antioxidant, anti-inflammatory, and photoprotective effects, inhibiting MMPs and modulating sirtuin and AMPK pathways.
- Formulation case studies report favorable cosmetic properties and compatibility with hyaluronic acid.
- Compared with some anti-aging actives, coumarins provide multi-target actions with fewer adverse effects, though regulatory constraints must be considered.
Methodological Strengths
- Integrative synthesis spanning historical, mechanistic, and formulation perspectives
- Mechanism-focused discussion linking molecular targets to skin aging phenotypes
Limitations
- Narrative review without systematic search or meta-analysis
- Clinical evidence is limited; many data are preclinical or formulation case reports
Future Directions: Standardized in vitro-to-clinic pipelines, head-to-head comparisons with retinoids/peptides, dermal PK/PD studies, and sustainability-focused sourcing and green synthesis.
BACKGROUND: Coumarins, naturally occurring benzopyrone derivatives, have long been valued in traditional medicine, fragrance industries, and therapeutics. Recent interest has surged around their anti-aging properties, particularly in skincare, due to their antioxidant, anti-inflammatory, and photoprotective effects. OBJECTIVE: This review explores the role of coumarins as promising agents in combating skin aging, offering a natural alternative to synthetic cosmetics and contributing to the deve
3. Long-Term Effects of Tear Trough Hyaluronic Acid Filler: A Retrospective Study.
In 155 patients treated from 2007–2023, tear trough hyaluronic acid fillers improved infraorbital hollowing with benefits sustained through 18 months. Multivariate regression showed no significant differences in MIHAS grade changes between 6, 12, and 18 months, challenging the conventional 6–12 month durability expectation.
Impact: Provides practice-informing evidence that under-eye filler durability can extend to 18 months, aiding patient counseling, interval planning, and product selection in aesthetic dermatology.
Clinical Implications: Clinicians can consider longer follow-up intervals and set patient expectations for extended efficacy; technique (27G 1-inch cannula; mean 0.45 mL/side) and product heterogeneity should inform individualized plans and safety monitoring.
Key Findings
- Significant MIHAS improvements persisted at 18 months after TT-HA filler treatment.
- No significant differences in MIHAS grade changes between 6, 12, and 18 months in multivariate models.
- Mean injected volume was 0.45 mL per infraorbital hollow using a 27G × 1-inch cannula across multiple HA products.
Methodological Strengths
- Relatively large retrospective cohort (n=155) spanning 16 years
- Standardized severity grading (MIHAS) and multivariate regression analysis
Limitations
- Retrospective, single-center design without a control group
- Heterogeneous HA products and potential variability in technique and follow-up
Future Directions: Prospective, controlled studies comparing products, techniques, and adjuncts (e.g., cannula vs. needle) with standardized outcomes and safety reporting beyond 18 months.
OBJECTIVE: This retrospective study aims to assess the extended efficacy of tear trough hyaluronic acid (TT-HA) filler treatments beyond the commonly reported duration of 6 to 12 months. METHODS: A retrospective analysis of 155 patients who received TT-HA filler treatments from 2007 to 2023 was conducted. Patient records and photographs were reviewed, and the severity of infraorbital hollowing was graded using the Merz Infraorbital Hollow Assessment Scale (MIHAS). Multivariate regression model
