Seborrheic keratoses are known for their distinct appearance. They often look like they are pasted or “stuck on” the skin’s surface, which helps differentiate them from other types of growths. These spots can vary in color from light tan to dark brown or even black, and their surfaces can be smooth or rough.
The texture can range from slightly raised to rough and wart-like. These characteristics make them easy to identify for dermatologists, but if you’re unsure, a professional evaluation is the best course of action.
4. Who Gets Seborrheic Keratoses and Why They Suddenly Multiply
Seborrheic keratoses are more common in older adults, typically appearing after age 40. Genetics play a significant role in their development, with some families experiencing them more frequently than others. Hormonal changes, sun exposure, and skin friction are also thought to contribute to their formation.
It’s not uncommon for these spots to multiply over time. While they can appear one by one, they also tend to occur in clusters. A sudden increase in number should be monitored, but it’s often a benign process associated with aging.
