Skin diseases are quite common. In a recent questionnaire-based study of the Heidelberg population, more than 40 % of responding individuals stated they had had a skin disease during the last 12 months. Adequate skin care has an impact on several skin diseases and may assist the healing process. It has been shown that the use of proper moisturisers may reduce the need of other topical pharmaceutical products such as topical corticosteroids (cortisone) in atopic dermatitis. On the other hand, the use of inadequate skin care products may induce or exacerbate skin diseases. Therefore, the following information focuses on how to positively influence the healing process of several skin diseases by applying an appropriate skin care regimen.
