![]() ![]() Towards the Fifties, papilloma virus, responsible for the formation of warts, was isolated and identified as a virus with a double stranded DNA belonging to the Papovavirus family. Warts were first mentioned around 30 BC, when Aulus Cornelius Celsus wrote about “growths” on the skin, which seem to refer to what today are commonly referred to as warts. The skin undoubtedly performs essential functions for the health and well-being of the entire organism: it is therefore important to maintain its integrity and functionality adopting correct hygiene habits that include specific cleaners and, in case of pathologic events, using appropriate natural remedies. The most frequent are pressure sores, ulcerations, burns, injuries, bruises, erythema, abrasions, cuts, etc. The skin is a very delicate organ that can incur several problems, either injuries or irritations. In fact, it contains blood vessels carrying nutrients to the skin itself, as well as the sebaceous and sweat glands, in charge of regulating the body temperature nerve endings that receive impulses coming through the epidermis hair roots. ![]() Its principal function is to support and nourish the skin. The dermis is the layer right under the epidermis. The principal functions of this layer of skin are: to form a physical barrier against external agents prevent dehydration of the body prevent penetration of bacteria or other pathogenic agents protect the body from sunburns by means of special cells called melanocytes, which produce a protein called melanin, responsible for skin coloration rapidly repair the skin in case of injuries. The epidermis is the outer part of the skin, formed by several layers of cells, of which the most external ones are basically dead but resistant to external agents. For this reason, colour varies not only according to the ethnical group but also with individuals and, even though in small nuances, it also changes in different body regions of the same individual. In the human species, skin colour depends on many variables (thickness of the corneous layer, level of blood perfusion, presence and optical absorption of melanin, vitamin A dimer, hemoglobin). ![]() The skin is formed by two layers: the epidermis and the dermis. The surface of the skin is not uniform: it has a very complex design that varies due to the presence of parallel patterns along its surface that determine, particularly on the fingertips, typical figurations (called “fingerprints”) that vary from individual to individual. Last but not least, it is seat of nerve endings of the sense of touch. It plays a fundamental role in protecting the body from heat and cold (thermoregulatory function), from injuries and from aggressions of external pathogenic agents. Its main function is to protect organs and internal tissues from aggressions of the “world outside” and therefore constitutes a physical barrier covering the entire body surface. The skin is one of the largest organs of the human body: in fact, if stretched out completely it can reach 2 square metres and in terms of weight it makes up 16% of the total body weight. ![]()
