The skin is the largest organ in the body. It is our protection against the environment, such as bacteria, chemicals and temperature; it regulates body temperature. Skin consists of three layers, the epidermis, and dermis and below that, the subcutaneous tissue. The skin takes about one month to renew; new cells are formed in the subcutaneous tissue and emerge as the epidermis to shed on a daily basis as we go about our daily activities. It often visually indicates a sign of any disorder or illness in the body e.g.: a rash in shingles or chickenpox. Like any other organ inside the body, the skin needs nutrients on a daily basis.
