The increased acidity of the skin is related to its ability to protect itself from harmful microorganisms. The acidity of the skin is determined on a scale from 1 to 14, which takes into account its ratio to alkalinity. The increased acidity of the skin guarantees its bacteriostatic and bactericidal effect. The natural pH or acidity of the skin is normally around 5.5. However, the natural pH of the mucous membranes of the intimate area has lower values ​​- pH 4.6, which provides the highest protection against bacteria. In order to maintain a good balance of the microflora of the vagina and the natural defenses of the mucous membranes, it is necessary to take such care in hygiene as not to change their pH. When using ordinary toilet soaps, the natural balance of the mucous membranes changes to alkaline due to their high pH 9-11. This destroys epidermal lipids, which are the main structures of the stratum corneum, protecting against moisture loss. As a result, the mucous membranes become dry and susceptible to infection. A pH lower than 4.5 leads to irritation and redness of the more sensitive skin, such as the mucous membranes. The use of detergents with an appropriate pH, which do not contain sodium salts of fatty acids, is important for preserving the protective mechanism of the mucous membranes. The modern woman has high demands and expects her intimate lotion to offer, in addition to effective protection, long-lasting freshness. NIVEA Intimate products do not contain dyes or alkaline soaps. The formulas contain lactic acid, a substance natural to the vaginal flora, which maintains a constant low pH of 4.6. In this way, the intimate skin is kept 100% balanced and its healthy environment is ensured. NIVEA Intimate NATURAL contains lactic acid, natural chamomile extract and bisabolol, which contributes to the gentle care of the intimate area and pleasant freshness.
