A NONINVASIVE METHOD FOR MEASURING METABOLITES FOR SKIN HEALTH

摘要

A noninvasive method for diagnosing skin health in a subject comprising collecting a skin sample from the subject; detecting a level of one or more small molecule biomarkers in the epithelial cell sample/skin cell sample; diagnosing the subject as having a skin condition based on the level of a detected small molecule biomarker, wherein the detected small molecule is at least one compound chosen from: a compound generated by metabolism of amino acids, a compound generated by dipeptides metabolism, a compound generated by nucleic acids, a compound generated by metabolism of lipids, a compound generated by metabolism of carbohydrates, and mixtures thereof and further small molecule biomarkers as listed in Table 1. Further, a noninvasive method for evaluating the efficacy of products for skin health.
