Mutation-aware formulation: a genomic framework for equitable global dermocosmetics.

Despite advances in dermatogenomics, the global skincare industry continues to rely on generalized formulation strategies that overlook population-specific genetic variation. This study introduces a mutation-aware framework that bridges this translational gap through two novel metrics: the Mutation Burden Index (MBI)-which quantifies regional genetic vulnerability across nine core skin function domains-and the Population Compatibility Burden (PCB)-which measures the alignment between current commercial formulations and regional genomic needs. Using a curated database of more than 200 authenticated cosmeceutical products, we mapped ingredient functionality against regional MBI profiles. Results reveal a stark compatibility gap: regions with the highest burden (e.g., Africa, South Asia) receive the least functionally aligned products, with average compatibility scores as low as 0.35. In contrast, Europe-despite lower burden-achieves scores > 0.70. Simulated formulations informed by MBI scores increased compatibility to > 0.80 in underserved regions, demonstrating the potential for 50% gains in biological relevance without individualized genotyping. A machine learning classifier trained on MBI vectors achieved strong performance (F1 = 0.837), and SHAP-based interpretation highlighted barrier and pigmentation pathways as key drivers of product-region mismatch. In contrast to commercial AI platforms offer black-box personalization with minimal genomic input and no interpretability, our model provides transparent, biologically grounded, and reproducible formulation logic. By repositioning personalization from individual-level luxury to population-scale equity, this work establishes a practical foundation for genomically aligned skincare-anchored in functional biology, enabled by AI, and designed for global impact.
