[Way of drying the skin and the renewal of skin surface activity].

Abstract

The author tried to evaluate the impact of the way of drying the skin upon the renewal of its surface acidity, using a linen towel, paper towel, cellucotton and a stream of dry air. 20 persons were evaluated. Prior to the study, 1% solution of "BHP" soap had been put on their skin. PH was measured at the skin surface by a pH-meter (produced by "Radelkis") using a combined glass and calomel electrode. This method of skin drying was considered the best one, after which the average time of pH value renewal on the skin surface was the shortest, which amounted to the recovery of pH to the initial value. The way of drying the skin was found to have a significant impact on the time of pH renewal. The results were indicative of advisability of the use of linen towels.
