PROBLEM TO BE SOLVED: To provide a method for noninvasively evaluating a moisture permeation barrier function of skin without being affected by physiological phenomena other than a skin function and the existence of an organic solvent.SOLUTION: Raman spectrum from the surface to inside of skin is measured, and an intensity change of a peak derived from a lipid molecule in the spectrum, having a correlation to a transepidermal water loss (TEWL), is measured, so that a moisture permeation barrier function of skin can be evaluated more accurately and noninvasively without being affected by factors other than a skin function. |
