Your skin is your body’s largest organ and first line of defense. This “covering” is a complex system made up of nerves, glands, and cell layers, each having a role in your health. It serves as a buffer that helps protect you from extreme temperatures and toxic chemicals, while also producing antibacterial compounds that defend you against infection. Your skin also plays a role in the production of vitamin D.
Although your skin is capable of all of these functions, it needs protection, too. If not cared for properly, it can become dry and rough, produce wrinkles, and/or become susceptible to certain skin problems.
You should be careful with what you apply on your skin. danielle71/iStock
