Seborrheic keratosis is one of the most common skin growths seen in older adults. These lesions often appear suddenly, multiply over time, and can be alarming at first glance. Their rough texture, dark color, or raised appearance may raise concerns about skin health or more serious conditions.
Despite their striking look, seborrheic keratoses are usually benign. Understanding what they are, why they appear with age, and when they should be evaluated helps separate reassurance from necessary vigilance.
What Is Seborrheic Keratosis?

Seborrheic keratosis refers to a non-cancerous skin growth that develops on the surface of the skin. These growths often appear as waxy, scaly, or slightly raised patches that seem “stuck on” rather than growing from within the skin.
They can vary widely in color from light tan to dark brown or black and in size. While their appearance can change slowly over time, they typically do not cause pain. Seborrheic keratosis is a diagnosis of appearance and behavior, not discomfort.
Why Seborrheic Keratosis Is Common in Seniors
Age is the strongest risk factor for seborrheic keratosis. As the skin ages, cell turnover slows and regulatory mechanisms become less precise. This can lead to localized overgrowth of skin cells, resulting in these benign lesions. Genetic predisposition also plays a role, explaining why some individuals develop many lesions while others develop few. Their appearance reflects skin aging rather than disease.
How Seborrheic Keratosis Typically Appears
Seborrheic keratoses often develop gradually but may seem to appear suddenly.
They are commonly found on the torso, back, chest, face, or shoulders. The surface may feel rough, crumbly, or waxy. Some lesions may itch or become irritated if rubbed, but they generally remain painless. Although benign, their dark or irregular appearance can cause concern.
When Seborrheic Keratosis Should Be Evaluated
While seborrheic keratoses are not dangerous, changes in appearance should not be ignored.
Rapid growth, bleeding, sudden inflammation, or a lesion that looks significantly different from others warrants closer attention. Because some skin cancers can mimic benign lesions, professional evaluation is important when doubt exists. Monitoring change is more important than appearance alone.
Why Aging Skin Makes Lesions More Noticeable
Aging skin becomes thinner and more translucent, making surface changes stand out more clearly.
Reduced elasticity and slower healing can also cause lesions to feel more prominent or become irritated by friction. What once went unnoticed may become more visible with time. Visibility does not equal severity.
Reassurance With Awareness
Seborrheic keratosis is not a sign of poor health, infection, or neglect. It is one of the most common benign skin findings in later life.
Reassurance comes from understanding its typical behavior and knowing when to seek further assessment. Awareness ensures peace of mind without unnecessary alarm.

Common, Benign, but Worth Observing
Seborrheic keratosis is extremely common in seniors and is almost always harmless. Its appearance may be unsettling, but it rarely signals danger.
The key lies in observation rather than anxiety. Stable lesions are reassuring, while evolving or atypical changes should prompt evaluation to rule out other conditions.
