How does the skin's natural barrier work?
The upper layer of skin acts as a protective barrier against environmental influences and prevents moisture evaporating from the skin. The protective acid mantle is initially formed by the body's own lipids. The sound lipid structure ensures sufficient moisture and makes normal skin look healthy and radiant. With this barrier the skin is also protected from damaging micro-organisms, infections, irritations and allergies. So that normal skin doesn't develop into dry or sensitive skin, the balance of moisture and lipids must be maintains through a consistent normal skin care routine, this supports your skin keeping it healthy, resistant and elastic for a long time.
What is behind a pH level?
A pH level is the measurement of the concentration of acid or alkaline's in liquids. Our skin consists largely of water, it has it's own slightly acidic pH level as a results of the skin's own substances such as sebum, sweat and water. This pH level plays an important role in correct skin care whether you have normal or combination skin. The protective acid mantle has an average pH of 5.5. By contrast, normal soap has a much higher pH level - so the skin's pH level is raised when cleansing. Only healthy and normal skin manages to reduce the pH to its natural level in a short amount of time. Find more skin care tips of beautiful skin. Find more skin care tips for beautiful skin.
