Our skin is covered by a hydrolipid film, which mainly consists of sweat and sebum. This film has a slightly acidic pH (5.5–6), which promotes a balanced microbiota. Some cosmetic products increase pH on the surface of your skin, which negatively affects the condition of dermal microbiota and impairs the epidermal barrier function. If that happens, the key thing is to restore the physiological pH level as soon as possible — this is possible by the quick and easy application of the Pure On Face Mist.
