Estimate biomarker levels (Key protein to evaluate skin characteristics) in stratum corneum and cell form using deep learning

AI substitutes for biochemical analysis and image evaluation requiring time and specialized analysis equipment.

  • A cosmetics manufacturer* provides counselling and personal solution programs based on the biomarker levels in stratum corneum measured through biochemical analysis. Biochemical analysis, however, takes time, and requires specialized analysis devices. Although there was a known method for image evaluation of the form of stratum corneum cells, evaluations require specialized knowledge and take time, so they were difficult to apply.
  • This technology uses deep learning models to estimate biomarker levels and recognize cell form from an image of the skin stratum corneum sample, to provide services quickly and at a low cost.
  • *) FANCL Corporation


  • Alternative method of biochemical analysis for counselling based on skin stratum corneum samples for customers at cosmetics sales outlets
