Your skin is like a superhero suit that grows with you and protects you your whole life! It starts forming when you’re just a tiny baby inside your mom, and when you’re born, it’s soft and delicate. As you grow, your skin gets stronger, helps keep you warm or cool, and even heals itself if you get a scrape. It also helps your body make vitamin D when you’re out in the sun. When people get older, their skin changes again—it might get wrinkly or heal slower. Your skin is always working hard to keep you safe and healthy!
