It takes about five weeks for new cells to work their way to the epidermis. The thickness of this layer of skin varies depending on the part of the body. For example, the skin on your heels is different than the skin on your arms. Within the epidermis are specialized cells that alert your immune system to viruses and other infectious elements. Hair follicles and sebaceous and sweat glands are found in the dermis. The collagen and elastin in the dermis give skin its flexibility. The blood vessels in the dermis help regulate body temperature while the nerves of the dermis relay sensations of touch, pain and temperature to your brain. The subcutaneous acts as a cushion against bumps and as an insulator.
