What a skin-transport model can help us explore
A computational preprint links skin morphology with simulated transport across a set of 50 chemicals.
The research question
Tesfamarian and colleagues describe two- and three-dimensional skin models incorporating regional and age-related morphology. Their 2025 preprint simulates transdermal transport for 50 chemicals and examines the influence of diffusion, partitioning and molecular properties.
Simulation is conditional evidence
A model’s prediction depends on its geometry, parameter values, boundary conditions and assumptions. It is not itself a measurement from a clinical population. Findings from a particular formulation or modeled skin region should not be assumed to transfer to another without evaluation.
A useful role in research
Our editorial interpretation is that such models can help formulate experimental questions and identify influential parameters. A clear comparison with independent experimental data is still needed before treating a prediction as evidence for a defined application.
