Seborrheic Keratoses (also known as “Barnacles”)
Would you believe that you probably have an SK somewhere on your skin right now? Seborrheic keratoses are extremely common, especially as we get older. The good news—they’re completely harmless. Still, it’s natural to wonder what they are and whether they need attention. Here’s what you should know.
Are These Lesions Cancerous?
No, seborrheic keratoses are not cancerous and do not pose a risk to your health.
However, it’s easy to confuse them with certain types of skin cancer.
Skin cancers can sometimes appear as scab-like lesions that bleed and never fully heal. Seborrheic keratoses can look similar; often raised, scaly, or crusted and may bleed if scratched or irritated. Because they can mimic other conditions, it’s always best to have new or changing growths evaluated by a board-certified dermatologist. When in doubt, get it checked; it’s better to be safe.
Treatment Options
Seborrheic keratoses don’t require treatment unless they’re bothersome or irritated, or you’d simply prefer to remove them for cosmetic reasons.
Common treatment options include:
Cryotherapy (Liquid Nitrogen)
A quick, in-office procedure where the lesion is carefully frozen. The area may appear red or inflamed for a short time, then gradually scab and flake off. In most cases, once removed, that individual spot does not return.
Electrocautery (Hyfrecation)
For thicker lesions, your dermatologist may numb the area and use a small device that delivers controlled electrical current to remove the growth. A gentle curette is then used to clear away the treated tissue, and a thin layer of petroleum jelly is applied as it heals.
Both procedures are quick and generally well-tolerated. Healing time depends on the size and depth of the treated lesion, but most patients can return to normal activities right away.
Can They Come Back?
Once seborrheic keratoses begin to appear, it’s common to develop more over time. This tendency is related to genetics and aging skin, not to any behavior or lifestyle. While treated spots rarely regrow, new ones can form elsewhere.
