Abstract

Novel 3-amino-tetrahydro-1,3-thiazine-2,4-diones as well as skin treating compositions on the basis of a physiologically compatible carrier and customary additions containing these novel 3-amino-tetrahydro-1,3-thiazin-2,4-dione derivatives as active ingredients for thickening the epidermis. The skin treating compositions are applied 1-2 times daily on the skin for about 3 to 4 weeks. Due to the thickening of the epidermis they cause a strengthening of the skin protection, in particular against sun rays, cold and the contact with harmful environmental substances of all kinds. Moreover, the skin treating compositions are suitable for prophylactically fighting the so-called ageing of skin.
