Seborrheic Keratosis: Why It Doesn’t Always Look the Same – If you’ve ever found a new mark or bump on your skin and weren’t sure what it was, you’re not alone. One of the most common things I see in clinic is something called Seborrheic Keratosis. It’s completely harmless—but the way it looks can vary so much that it often causes unnecessary worry. You might have one already, or a few, or maybe you’re here because you noticed something that’s changed and you’re trying to figure out what it is. I want to show you just how different these little growths can look—and reassure you a bit in the process.
