Siriderma® alkaline specialist care is proven to maintain and support the natural protective barrier of the skin. At the same time the alkaline pH value of SIRIDERMA® products helps to prevent acidosis of the skin.
An imbalance in the acid-base balance has an adverse impact on human health. To avoid it, our body is permanantly striving to keep its pH at a constant level. It draws on all possible alkaline reserves - bones for example - to achieve this constant pH. In addition, it tries to excrete excess acids and / or store them in the connective tissue. Cellulitis and a premature formatoin of wrinkles can be the effects of a chronic hyperacidity on the outer appearance. Alkaline skin care helps to counteract excess acidity.
