Skin moisturization is one of the importantsubjects in dermatology and cosmetology. Theskin surface hydration levels before and afterthe topical application of several vehicles wereassessed using 3.5 MHz conductancemeter. Inaddition, three dimensional changes in hydrationstate of the stratum corneum were also assessedby stripping.<BR>Petrolatum was most effective in increasing thewater content of the stratum corneum probably byforming lipid film over the stratum corneum;thus it possesses an ability to retain water fromsurface to deep layer, throughout the stratumcorneum beneath its film. On the other handvanishing cream induced a dehydrated statein the superficial horny layer, possibly by theabsorption of water from the superficial hornylayer and by the evaporation of the absorbedwater to external air. The three dimensionalanalysis of the water in the stratum corneumusing stripping is useful for the evaluation ofthe the function of skin moisturizers as watersorption-desorption test.
