|Various factors influence the moisture of skin. In winter the skin needs more protection against moisture loss, since humidity in cold and dry weather conditions is very low. It even decreases further in heated rooms. More and more the problem of extended moisture loss can be observed even in summer months due to the more frequent use of air conditioning. With increasing age the skin’s capacity to retain moisture decreases. On the one hand this phenomenon is based on the hormonal changes of women at higher age, on the other hand it is based on a natural thinning of the skin’s epidermis. The skin needs active ingredients that substantially improve its moisture retention capacity.
