Skin is the human body's largest organ. Our skin acts as a waterproof, insulating shield, protecting our body against extreme temperature, damaging sunlight, and harmful chemicals. It also releases antibacterial substances that prevent infections and produce vitamin D for healthy bones. Moreover, our skin is a gigantic sensor packed with nerves for keeping the brain in touch with the outside world. Our skin is just an amazing organ and it deserves the best care we can give it.
