Rox Anderson is a really smart doctor who knows a lot about skin and how it works. He figured out that if you use really, really bright light (like from a laser) on a skin problem, it can make it go away or get better. Imagine if you have a stain on your shirt and your mom uses a bright light to get it out - that's kind of like what Rox Anderson does, but with your skin. He also figured out that when your skin gets hurt or damaged, your body tries to fix it by making new skin cells. So, he made a special machine that can use light to tell your body to make more skin cells and heal faster. It's like giving your skin a superpower! Rox Anderson's work has helped a lot of people with skin problems and made their skin look and feel better!
