The skin is the largest organ in the human body that supports a number of bodily functions related to our immune system, sensory perception, and homeostasis of the body. The skin consists of three main layers, in addition to a number of sublayers, that all perform different actions that all play a role in keeping us healthy. As we go through some of these important functions, we will gain a better understanding for why we should maintain our skin and keep it healthy for as long as we age.
Collagen is the most common structural protein necessary for humans and other mammals to sustain life. Apart from lending support and structure to our bones and muscles, collagen plays an important role in skin health. The function of collagen in wound repair and scar formation is a crucial aspect of this vital protein that helps keep our skin healthy and vibrant. Collagen is of such mainstream importance today that a simple Google search will yield countless results for products that supposedly help with collagen synthesis in the body. In particular, the beauty, nutrition, and cosmetics industries have benefitted greatly by promoting collagen in their health and skin care products.
