The basis of the methodology for diagnosing the condition of the epidermis of the facial skin for the purpose of personal selection of cosmetics has been developed. The method is based on optical terahertz spectroscopy in the scanning mode of samples from 0 to 3.8 THz. The dependence of the reflection coefficient of the epidermis tissues of various types of facial skin on the water content in them in the THz range is established. The spectral mechanisms of functional evaluation of cosmetics of different skin types are determined. The obtained confidence intervals and the probability of repeatability of the experiment (more than 95%) show the prospects of using this technique for various diagnostic studies
