Seborrheic Keratosis: Why It Doesn’t Always Look the Same

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.

What Exactly Is It?

Seborrheic Keratosis (or SK for short) is a very common, non-cancerous skin growth. It’s not caused by an infection, it’s not contagious, and it doesn’t mean anything serious is going on. They tend to show up more as we age and are often linked to genetics. Some people get just one. Others get clusters.

What’s tricky is how they appear. As I said Seborrheic Keratosis don’t always look the same and that’s where the confusion often starts.

They Come in All Shapes and Textures

Some are completely flat and smooth. These can look like sunspots or age spots and might blend into your skin so well you barely notice them.

Others are crusty or rough, almost like a small scab that won’t go away. These can sometimes flake or catch on clothing, especially if they’re raised.

Then there are the waxy ones. These tend to have a shiny surface and look like they’ve been stuck onto the skin, like blobs of candle wax.

I also see some that look a bit fibrous or like they’re peeling. They can be a little dry, flaky, or textured in a way that makes them feel different from the rest of your skin.

Color-wise, they’re all over the place—light brown, dark brown, grey, black, remember Seborrheic Keratosis don’t always look the same.

When to Get It Checked

Even though Seborrheic Keratoses are benign and nothing to worry about, I always recommend getting any new or changing skin marks looked at—especially if they bleed, itch, or just don’t feel right to you. It’s always better to check and be sure, rather than guess.

Seeing Is Believing

To help you better understand what SKs look like, I’ve included a series of photos below. Each one shows a different version of this very common skin condition. You’ll see just how much variety there is—so if you’ve spotted something similar on your own skin, there’s a good chance it could be an SK.

 

You’re Not Alone

Seborrheic Keratosis is incredibly common, and even though it can look odd or feel uncomfortable, it’s usually nothing to worry about. Still, your peace of mind matters. If you ever notice something new or unusual, it’s always worth getting it checked.
