THE FUNCTION OF THE SKIN AND THE PILOSEBACEOUS UNIT
The skin is like a valuable coat that covers the whole body. In fact it is an organ linked to many internal functions of relevant and vital importance. It is a multifunctional organ of cutaneous respiration, secretion through the sebaceous glands, heat adjustment and sweating through sweat glands. Its structure is perfect, but it needs a lot of care and attention to remain intact and to protect the lifelong growth of healthy hair. It also provides immune protection against external harmful bacteria, viruses, dirt, etc. The stress of modern life and inadequate or aggressive hygiene can undermine the defences of the cutaneous bacterial flora causing multiple problems for the pilosebaceous unit.
