Treatment of surfactant-damaged skin in humans with creams of different pH values.
Pharmacology. 2005 Jan; 73(1):1-7.P

Abstract

Skin surface has an acidic pH, whereas the body's internal environment maintains a near-neutral pH. The physiological role of the 'acidic mantle' and the function of the pH gradient throughout the stratum corneum remain unexplained. The pH gradient has been suggested to activate enzymes responsible for the maintenance of the skin barrier function and to facilitate the desquamation process in the stratum corneum. The aim of the study was to investigate the influence of pH of a moisturizing cream on barrier recovery in surfactant-damaged human skin. Volunteers had their skin damaged with sodium lauryl sulphate and treated those areas with the cream, adjusted to either pH 4.0 or 7.5. The study did not prove the superiority of a cream of pH 4.0 to a cream of pH 7.5 regarding promotion of skin barrier recovery, since no significant differences (p > 0.05) were found in transepidermal water loss, blood flow and skin capacitance between the treated areas.
