Its job is crucial: to protect you from infections and other environmental assaults. The skin also contains nerves that sense cold, heat, pain, pressure, and touch.
The skin is composed of three layers: the epidermis, the dermis and subcutaneous tissue. Subcutaneous tissue is largely composed of adipose tissue, or fat tissue, that is made up of adipocytes, or fat cells. The amount of adipose tissue varies throughout the body. It's thickest in the buttocks, the palms of the hands and the soles of the feet.
