Seborrheic keratosis is a common, benign skin growth that often appears as people age. Though non-cancerous, these waxy or scaly lesions can be bothersome—both in appearance and in comfort—especially if they become irritated by clothing or friction.
At Metropolis Dermatology in Pasadena, we offer expert diagnosis and a range of modern treatments for seborrheic keratosis removal, tailored to your cosmetic goals and skin health needs.
What Is Seborrheic Keratosis?
Seborrheic keratoses are superficial skin growths that originate in the outermost layer of skin cells. While they may resemble warts or moles, they are completely non-cancerous and typically present with a waxy, raised, or “pasted-on” look. These lesions can appear on the face, neck, chest, back, or other sun-exposed areas and vary in color from tan to dark brown or black.
Some people develop a single growth, while others may notice multiple lesions forming in clusters over time.
What Causes Seborrheic Keratosis?
While the exact cause is still being studied, genetics appear to play a major role. People over the age of 50 and those with a family history of these growths are more likely to develop them. Contrary to popular belief, seborrheic keratoses are not caused by sun exposure, and they carry no increased risk of skin cancer—though they can occasionally resemble more serious skin conditions, making expert evaluation important.
Common Characteristics and Symptoms
These growths are usually painless, but they may cause irritation or self-consciousness depending on their size and location. Typical features include:
- Waxy or rough texture that appears stuck onto the skin
- Color variations ranging from light tan to dark brown or black
- Irregular shape or border, often oval or round
- Itching or irritation—especially when rubbed by clothing or jewelry
If you notice a change in a skin lesion or are unsure about a growth, a professional dermatologic exam is recommended.
Seborrheic Keratosis Removal Options
While seborrheic keratosis doesn’t require medical treatment, many patients opt for removal due to irritation or cosmetic concerns. At Metropolis Dermatology, we offer several safe and effective options for removal:
- Laser therapy – Uses targeted light energy to break down the lesion with minimal damage to surrounding skin
- Cryotherapy – Involves freezing the growth with liquid nitrogen, causing it to fall off over time
- Curettage – A minor procedure that gently scrapes away the lesion after numbing the area
- Electrocautery – Burns off the growth using a low-level electrical current
Your provider will assess your skin, location of the lesion(s), and treatment goals to recommend the best method for removal.
Frequently Asked Questions About Seborrheic Keratosis
Can seborrheic keratosis turn into skin cancer?
No—seborrheic keratosis is completely benign and does not increase your risk of developing skin cancer. However, it’s always a good idea to have any new or changing skin growth examined.
Do I have to get seborrheic keratosis removed?
Treatment is optional. Many people choose to remove them for cosmetic reasons or if they become itchy, irritated, or snagged on clothing.
How long does removal take?
Most in-office procedures take 20–30 minutes, depending on the size and number of growths.
Will it come back after treatment?
The treated lesion will not regrow, but new seborrheic keratoses may form in other areas over time.
Does insurance cover seborrheic keratosis removal?
Removal is often considered cosmetic and may not be covered by insurance unless the growth is causing irritation, bleeding, or discomfort.
