Marchionini’s Acid Mantle Concept and the Effect on the Skin Resident Flora of Washing with Skin Cleeen kept clean rather than specially cleansed. To us, the response of washed skin was a problem in its own right. … When used on the skin of living subjects, the method produced about the same high acidities (as in cadaveric skin, H.C.K.), with pH values ranging throughout from 5.0 to 3.0. Out of 40

In-Vitro Control of the Growth of Important Bacteria of the Resident Skin Flora by Changes in pHview of the aerobic conditions on the skin surface. The pH ranges investigated were 5.0–8.0 for S. aureus, and a slightly narrower range of 5.5–7.5 for P. acnes. Colony densities were determined photometrically. Growth was measured in terms of the specific growth rate (number of doublings per hour,
