At Metropolis Dermatology in Costa Mesa, CA, we offer safe and effective treatment options for seborrheic keratosis, whether for removal due to discomfort or aesthetic concerns.
What is Seborrheic Keratosis?
Seborrheic keratosis is a harmless skin growth that forms from the outer layer of skin cells. These lesions often have a “stuck-on” appearance and can develop as a single growth or in clusters. They are most commonly found on sun-exposed areas such as the face, neck, chest, and back.
Causes
The exact cause of seborrheic keratosis is not fully understood, but contributing factors include:
- Genetics: The condition tends to run in families, suggesting a hereditary link.
- Aging: Most individuals develop seborrheic keratoses after the age of 50.
- Unknown Triggers: Unlike other skin conditions, sun exposure is not a known cause.
These growths are non-contagious and do not pose an increased risk of skin cancer, though their appearance may resemble other skin conditions, making professional evaluation important.
Symptoms
Seborrheic keratoses vary in appearance, size, and texture but commonly include:
- Waxy, scaly, or rough patches that look as if they were pasted onto the skin.
- Color variations from light tan to deep brown or black, often darkening over time.
- Irregular shapes with a raised, bumpy surface.
- Mild itchiness or irritation, especially if rubbed by clothing or scratched.
What Are the Possible Treatments?
Seborrheic keratosis does not require treatment unless it causes irritation, bleeding, or cosmetic concerns. At Metropolis Dermatology in Costa Mesa, we offer several removal options to ensure quick and effective results.
Common Treatment Methods
- Laser Therapy: Uses precise laser energy to remove the growth with minimal scarring.
- Cryotherapy: Freezes the lesion using liquid nitrogen, causing it to fall off naturally.
- Curettage: A gentle scraping technique, performed after numbing the area.
- Electrocautery: Burns off the lesion using a controlled electric current.
During your consultation, our dermatologists will assess your skin and recommend the most effective treatment based on the size, location, and number of lesions.
