The subcutis makes the connection with the underlying structures. It consists of connective and fatty tissue. But this also performs important functions for our body: the fatty tissue serves as a heat insulator and energy store. The sweat and sebum glands, which produce the protective layer for the epidermis, are also found in the subcutaneous tissue. Besides these vital functions, skin has always played another role for us: as the mirror of our soul, it is an essential part of our beauty. We want it to be uniformly smooth, wrinkle-free and pure. Good care and protection from external factors are important in maintaining the beauty and protective functions of our skin. Here at Dermatest® we have made it our mission to test products which come into contact with our skin in order to prevent harm and prove the efficacy of skincare products.
