The skin harbours a resident flora adapted to a dry, nutrient-poor and acidic environment. Studies show that the surface pH influences the adherence and the composition of this flora.

The surface of the skin carries a very fine film in which sebum, sweat and water mingle. This mixture behaves like a natural emulsion, constantly renewed, and the barrier it...

The lipids that form the skin barrier are assembled in the stratum corneum by enzymes whose activity is optimal at acidic pH. When the surface pH rises, research observes a...

What happens at the skin surface when its pH rises
When the pH of the stratum corneum rises toward neutrality, the enzymes that assemble the barrier lipids slow down and the surface cells hold together less well. After ordinary washing,...

The “acid mantle” refers to the slight acidity of the skin's outermost layer. Research ranks it among its natural defences, alongside the lipid barrier, the low water content and the...

The pH of the skin surface averages 4.7
Measured on skin that has been neither washed nor cared for in 24 hours, the pH of the skin surface averages 4.7. This figure, from a study of 330 volunteers,...
