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.
What are the three layers of the skin? And what are their roles in scar formation? The skin is a complex organ, and the way it forms scars is part of an intricate and dynamic wound-healing process. The epidermis, dermis, and hypodermis layers of the skin each play pertinent roles in responding to trauma by forming scars. Understanding this is the key to understanding how our bodies heal themselves naturally and ward off infection.
