Summary
This week’s cosmetic-related literature highlights three high-impact directions: MRI-informed mechanobiological modelling for patient-specific prediction of post-surgical cosmetic deformation, rational discovery of potent tyrosinase inhibitors validated from enzyme assays to 3D human skin, and high-level evidence synthesis showing PRP yields comparable hair-density outcomes to topical minoxidil with higher patient satisfaction. Together they advance predictive planning, translational therapeutics for pigmentation, and evidence-based choices in aesthetic procedures.
Selected Articles
1. Computational Modeling of Patient-Specific Healing and Deformation Outcomes Following Breast-Conserving Surgery Based on MRI Data.
An MRI-informed multiscale mechanobiological framework integrated patient-specific breast and tumor geometries into finite element simulations of cavity healing and trained Gaussian process surrogate models for rapid prediction of breast surface deformation. The model identified breast density, cavity volume, breast volume, and cavity depth as key drivers of postoperative contraction and cosmetic asymmetry.
Impact: Fills a clinical gap by providing a personalized, actionable predictive tool that links imaging, biomechanics, and machine learning to anticipate cosmetic outcomes after oncologic breast surgery.
Clinical Implications: Can be used for preoperative counseling and surgical planning (incision placement, cavity management, oncoplastic technique selection) to reduce unexpected cosmetic deformity and downstream revision surgeries.
Key Findings
- Integrated preoperative MRI-derived geometries into finite element simulations of post-BCS healing.
- Gaussian process surrogate models enabled rapid prediction of breast surface deformation.
- Breast density, cavity volume, breast volume, and cavity depth were key predictors of contraction and deformation.
2. Discovery of Novel Dihydroxyphenol Tyrosinase Inhibitors for Treatment of Pigmentation: From Enzyme Screening to Three-Dimensional Human Skin Melanin Evaluation.
Through pharmacophore hybridization the authors designed novel dihydroxyphenol tyrosinase inhibitors with nanomolar enzyme potency and translated activity assessments into a 3D human skin melanin model, addressing efficacy and translational validation for depigmenting therapeutics.
Impact: Provides potent candidate molecules and a translational evaluation pipeline that overcomes prior gaps between enzymology and human skin effects—critical for safer, effective depigmenting agents.
Clinical Implications: These candidates, after toxicology and clinical testing, could yield new topical therapies for melasma and post-inflammatory hyperpigmentation with improved potency and potentially better safety profiles.
Key Findings
- Pharmacophore hybridization yielded novel dihydroxyphenol tyrosinase inhibitors.
- Most synthesized compounds showed nanomolar-range inhibitory potency in enzyme assays.
- Activity assessment extended from enzyme inhibition to a 3D human skin melanin model, supporting translational relevance.
3. Comparative Efficacy and Safety of Platelet Rich Plasma (PRP) versus Topical Minoxidil for Androgenetic Alopecia: A Systematic Review and Meta-analysis.
A PRISMA-compliant meta-analysis of nine RCTs (n=451) found no significant differences between PRP and topical minoxidil in hair density or terminal hair count, while PRP was associated with higher patient satisfaction and more negative hair-pull test results; heterogeneity in PRP protocols limits definitive conclusions.
Impact: Synthesizes randomized evidence directly relevant to clinical decision-making in cosmetic hair restoration and highlights where standardized PRP protocols and larger trials are needed.
Clinical Implications: PRP can be offered as an alternative to topical minoxidil for patients preferring procedural therapies or intolerant to minoxidil, but clinicians should counsel about protocol variability, expected outcomes, and the need for standardized regimens.
Key Findings
- Nine RCTs (451 participants) directly compared PRP with topical minoxidil.
- No significant differences in hair density or terminal hair count between PRP and minoxidil.
- Patient satisfaction favored PRP and negative hair-pull tests were more frequent with PRP.
