It has been scientifically determined that a slightly acidic, microscopic hydrolipidic film made up of lipids and persperation is responsible for protecting our skin.

This pH acid film is extremely important, because it allows the skin’s horny layer maintain a constant hydration level.

In order to effectively cleanse our skin, we must therefore be certain that the cleansing agents we use do not alter the skin’s hydration or pH levels, keeping in mind that the hydration level is regulated by the presence of N.M.F., sugars and lipidic substances.

The cosmetic cleansing agents most frequently used today include soaps and synthetic detergents such as shower and bath foams.

The damages caused by soaps are essentially linked to the modifications in the skin’s pH, which becomes more alkaline.

The synthetic detergents, on the other hand, have generally been formulated with a specific isoepidermic pH, and due to the synthetic materials they contain, nearly always provoke a vigorous defatting action, which cause the skin to become overly dry and dehydrated.
