If you’re like most people, you don’t give your skin much thought - until something goes wrong with it. Although your skin might not always get as much attention as it deserves, it’s hard to overstate its importance. Knowing a little bit about how your skin works may help you better understand how to care for it and the treatments your dermatologist prescribes. Get to know your skin with these facts.
Your skin is literally a protective barrier that shields your bones, muscles, and internal organs of from outside elements. It is packed with white blood cells and helps to stave off bacteria to prevent infections. When bacteria does breach the skin, it triggers your immune system to kick into gear to fight off the invaders. Skin also plays a crucial role in regulating body temperature. When it is cold, the blood vessels in your skin contract to keep the blood warm. When it’s hot, the blood vessels expand, which encourages sweating to help you cool down.
Your skin is made up for three layers: epidermis, dermis, and hypodermis. The epidermis is the top layer. It is also the thinnest layer. The epidermis protects against infection and contains the melanin that gives your skin color. It is made up of dead skin cells that are constantly shedding to make room for younger cells. The middle layer - the dermis - contains collagen, which gives your skin tightness. The dermis also contains nerves that alert you to pain, cold, and heat. The hypodermis is the link between skin and the underlying muscles and bones. It also helps to keep you warm.
