How it is measured
Electrical capacitance of the stratum corneum measured with a corneometer probe at a defined skin site after a standardised acclimatisation period, in arbitrary corneometer units. Site (cheek, volar forearm, palmar or dorsal hand), ambient temperature and relative humidity recorded with each finding; sites are reported separately and are not combined.
