Daily Cosmetic Research Analysis
Three studies advance cosmetic science and practice from complementary angles: metabolomics and machine learning map bioactive recovery from coffee waste for sustainable cosmetic actives; hydrophobic natural eutectic solvents tune cream stability, rheology, and sensory feel; and a diversity-aware facial assessment framework (FASTM) modernizes aesthetic consultation. Together they promote greener formulations and more culturally sensitive, patient-centered care.

- Culturally sensitive, patient-centered facial assessment
Selected Articles
1. Multisolvent metabolite profiling of coffee waste by UHPLC-HRMS/MS and molecular networking.
Using UHPLC-HRMS/MS, GC-MS, multivariate statistics, and molecular networking, this study shows that solvent polarity and raw material origin (green beans vs spent grounds; Arabica vs Robusta) dictate recovery of specific bioactives from coffee waste. Non-polar solvents favor lipids/sterols (especially from SCG), while ethanol enriches hydrophilic antioxidants like chlorogenic acid from GB, providing a roadmap for sustainable cosmetic ingredient development.
Impact: Provides a methods-driven map linking extraction strategy to bioactive classes in coffee waste, enabling targeted valorization for cosmetics and nutraceuticals. The integration of molecular networking and machine learning enhances reproducibility and transferability.
Clinical Implications: While preclinical, the workflow informs selection of sustainable extracts for cosmeceutical development (e.g., antioxidant-enriched vs lipid-rich fractions), streamlining safety and efficacy testing pipelines.
Key Findings
- Non-polar solvents recovered fatty acids and sterols preferentially, especially from spent coffee grounds.
- Ethanol extracted higher levels of hydrophilic antioxidants, including chlorogenic acid, particularly from green beans.
- PCoA and Random Forest showed solvent polarity and material origin drive metabolite variation and classification.
- Molecular networking visualized structurally related metabolite clusters and solvent/material-associated distributions.
Methodological Strengths
- Multi-platform analytics (UHPLC-HRMS/MS, GC-MS) with quantitative HPLC-DAD for key markers
- Integrated multivariate statistics (PCoA) and supervised machine learning (Random Forest)
- Molecular networking to contextualize structural relationships
Limitations
- No direct bioactivity assays; cosmetic efficacy remains to be validated
- Limited to five solvents and specific Arabica/Robusta materials; generalizability to other wastes uncertain
Future Directions: Link chemical profiles to bioactivity and safety, standardize extraction protocols, and evaluate scalability and lifecycle impacts for cosmetic-grade ingredients.
2. Cosmetic creams with caprylic acid-based Natural Eutectic Solvents: Stability, rheology and user perception.
Four caprylic/medium-chain-based hydrophobic NES at 10 wt% were integrated into an O/W cream. Three remained physically stable under 30-day accelerated aging, while a menthol-based NES caused phase separation with larger droplets and higher TSI. All creams were shear-thinning, and NES composition significantly modulated viscosity/yield stress and sensory attributes (odor, spread, pick-up, firmness).
Impact: Demonstrates a practical, sustainable route to tune both structure and sensory performance of creams using hydrophobic NES, supported by quantitative stability and rheology metrics.
Clinical Implications: Guides formulators toward eco-friendly NES selection to achieve desired feel and stability, with caution for menthol-based NES that destabilize emulsions. Supports development of greener topical vehicles potentially relevant to dermatologic products.
Key Findings
- Three of four NES-containing creams remained physically stable over 30 days of accelerated aging; menthol-based NES induced phase separation with larger droplet size and higher Turbiscan Stability Index.
- All formulations exhibited shear-thinning behavior; viscosity profiles and yield stress depended on NES composition.
- Sensory attributes (odor intensity, spreading, pick-up, firmness) were significantly altered by NES type.
Methodological Strengths
- Static multiple light scattering (Turbiscan) for quantitative stability tracking over time
- Comprehensive rheology (shear and oscillatory tests) linked to sensory panel assessments
Limitations
- Short evaluation window (30 days) and fixed 10% NES loading; no dermal safety or clinical performance data
- Limited to four NES systems; generalizability across actives and emulsifier systems untested
Future Directions: Extend stability to real-time/long-term studies, map NES concentration-response, evaluate skin compatibility and active delivery, and test across emulsifier systems and consumer cohorts.
3. Current Standards of Facial Assessment and Opportunities for Improvement.
A multidisciplinary expert panel reviewed literature and cross-population market research to propose the Galderma Facial Assessment Scale (FASTM), a five-domain framework (skin quality, facial shape, proportions, symmetry, expression) for standardized yet flexible facial assessment. The framework addresses cultural variability and supports patient-centered, diversity-aware aesthetic planning.
Impact: Responds to a critical gap by operationalizing culturally sensitive assessment in aesthetic medicine, with a structured tool that can harmonize consultations across diverse populations.
Clinical Implications: Encourages adoption of structured, diversity-aware consultations using FASTM, potentially improving communication, goal alignment, and equitable outcomes across ethnicities and genders.
Key Findings
- Significant variability exists in aesthetic ideals across racial, ethnic, and gender groups, outpacing Western-centric assessment norms.
- The Galderma FASTM provides a five-domain framework (skin quality, facial shape, proportions, symmetry, expression) for adaptable, objective evaluation.
- Combining literature synthesis with 2021–2022 market research grounds the framework in both evidence and contemporary patient preferences.
Methodological Strengths
- Multidisciplinary expert consensus across dermatology, oculoplastic, and plastic surgery
- Integration of literature with cross-ethnic market research to capture contemporary preferences
Limitations
- Not a PRISMA-compliant systematic review; lacks prospective validation and outcome data
- Potential industry affiliation bias and need for cross-cultural psychometric validation
Future Directions: Prospectively validate FASTM’s reliability, patient-reported outcomes, and linkage to clinical results; assess digital tool performance and training impact across diverse settings.
