We take special care of our skin because it's the most visible part of who we are physically. But, do you know exactly what your skin does for you? Why does collagen matter? And what happens within your skin that causes wrinkles and other changes?
The functions of your skin
Your skin is one of the largest organs in your body. In an average adult, it accounts for about 12 to 15 percent of total body weight and covers almost 21 square feet of surface area. Contrary to popular belief, the skin is much more than a mere water-resistant covering for the body; it is a very complex organ system with many important functions that aid in maintaining homeostasis.
To start, your skin provides your first line of defense as a barrier from harmful items in the external world. This makes it a vital part of your immune system. It protects you from variations in temperature, micro-organisms, pathogens, radiation, and chemicals.
Next, the skin regulates several aspects of your physiology. It controls your body temperature via sweat and hair and changes in your peripheral circulation and fluid-balance via sweat. This makes the skin an important organ of your excretory system and vital for detoxification. Your skin also acts as an endocrine organ and is necessary in the synthesis and storage of vitamin D, which is actually a hormone.
The skin also contains an extensive network of sensory nerve cells that detect and relay changes in your environment. There are separate sensory receptors in the skin for heat, cold, touch, and pain. Additionally, the skin also has a major role in physical attraction between people and reproduction through exhibiting sex characteristics and emitting pheromones. It also matters for aesthetics and communication, because when others see our skin, they can assess our mood, physical state, health status, age, and attractiveness.
