How Long Does A Seborrheic Keratosis Last?
If you have noticed a rough, slightly raised brown patch on your skin, you may be wondering whether it will disappear on its own. One of the most common questions patients ask is how long seborrheic keratosis lasts and whether it is temporary.
In most cases, seborrheic keratoses do not go away on their own. Once they appear, they typically persist unless they are professionally removed.
This article explains how long they last, whether they can spread, when treatment is appropriate, and what to expect if you choose removal.
What Is Seborrheic Keratosis?
Seborrheic keratosis is a very common, benign skin growth that often appears as a waxy, slightly raised patch. It can range in colour from golden brown to dark brown or almost black. These lesions are frequently described as having a “stuck-on” appearance, as though they sit on top of the skin rather than growing from within it.
They can develop anywhere on the body, particularly on areas exposed to the sun. While completely harmless, they can become cosmetically bothersome or irritated by clothing.
By the age of 40, around 30% of the population have at least one seborrheic keratosis, rising to approximately 75% by the age of 70. Their frequency increases with age, which is why they are often considered a normal part of skin ageing rather than a medical problem.
Do Seborrheic Keratoses Go Away on Their Own?
Seborrheic keratoses are considered permanent unless treated. They may remain the same size for years, or they may gradually become thicker, darker, or more numerous with age.
While the appearance can change slowly over time, spontaneous resolution is uncommon. If a lesion disappears, it is more likely that it was misidentified rather than a true seborrheic keratosis.
Can They Get Worse Over Time?
Although benign, seborrheic keratoses can:
- Increase in number with age
- Become thicker or more raised
- Darken in colour
- Become irritated or itchy
- Catch on clothing and bleed
They do not spread in a contagious way, but new lesions may develop in different areas over time, particularly in individuals with sun-damaged skin or a genetic tendency.
When Should You Consider Seborrheic Keratosis Removal?
Seborrheic keratoses are harmless and do not require treatment for medical reasons in most cases. However, that does not mean they should simply be ignored. Many patients choose removal when the lesion becomes bothersome, changes in appearance, or affects their confidence.
You may wish to consider removal if the lesion:
- Becomes irritated, itchy, or painful: Raised growths can catch on clothing, jewellery, or shaving, leading to repeated irritation and discomfort.
- Bleeds due to friction: The surface can become inflamed or rub away, particularly on the trunk, neck, or scalp.
- Causes cosmetic concern: Larger or darker lesions on visible areas such as the face, chest, or hands can affect self-confidence.
- Changes in appearance or causes uncertainty: Any new, rapidly changing, or unusually pigmented growth should be professionally assessed. While seborrheic keratoses are benign, it is important to distinguish them from more serious conditions such as melanoma.
- Appears in multiple new areas: A sudden increase in the number of lesions can cause understandable concern and may warrant review.
Professional evaluation is important before removal. A qualified clinician can confirm the diagnosis, rule out skin cancer, and discuss the most appropriate treatment option for your specific case.
Seborrheic Keratosis Removal Procedure
At Waverley Park Minor Surgery Clinic, seborrheic keratosis removal is a straightforward minor procedure performed under local anaesthetic. The goal is to remove the lesion completely while preserving the surrounding healthy skin and achieving a neat cosmetic result.
Step 1: Initial Consultation
Your appointment begins with a thorough clinical examination. The doctor will assess the appearance, size, and location of the lesion and confirm the likely diagnosis.
During this consultation, you will have the opportunity to:
- Ask questions about the procedure
- Discuss expected recovery time
- Understand possible risks, including scarring
- Review your personalised treatment plan
If there is any diagnostic uncertainty, this will be addressed before proceeding.
Step 2: Preparing the Area
On the day of treatment, the area is carefully cleansed. Local anaesthetic is administered to numb the skin and ensure the procedure is comfortable. You may feel brief stinging during the injection, but once numb, the treatment itself should not be painful.
Step 3: Removal of the Lesion
The seborrheic keratosis is carefully excised or removed using precise technique. Surrounding healthy tissue is preserved wherever possible to support optimal healing and cosmetic outcome.
The procedure typically takes around 30 minutes, depending on the size and location of the lesion.
Step 4: Pathology Confirmation
As part of a comprehensive clinical approach, all removed tissue is sent to a pathology laboratory for detailed analysis. This provides confirmation of the diagnosis and reassurance for both you and your GP.
Step 5: Aftercare Guidance
After removal, you will receive clear instructions on how to care for the treated area. While a small scar may form, this usually fades significantly over time with proper wound care.
Most patients return home shortly after the procedure and resume light activities the same day.
How Long Does Recovery Take After Treatment?
Healing time depends on the size and location of the treated area. Most patients experience:
- Mild redness or tenderness for a few days
- Formation of a small scab
- Gradual regeneration of new skin
Complete healing usually occurs within a few weeks. Proper wound care and keeping the area dry during early healing help support the best cosmetic outcome.
Will It Come Back After Removal?
Once a seborrheic keratosis is fully removed, it does not typically return in the same spot. However, new seborrheic keratoses may develop elsewhere over time.
These growths are common with ageing and sun exposure, so ongoing skin monitoring is important.
Can Seborrheic Keratoses Be Prevented?
While they cannot be completely prevented, risk may be reduced by:
- Protecting skin from excessive sun exposure
- Using appropriate sun protection
- Avoiding prolonged UV exposure
- Attending regular skin checks
Early assessment allows prompt treatment if new growths become bothersome.

Frequently Asked Questions
How is seborrheic keratosis diagnosed?
Seborrheic keratosis is usually diagnosed through clinical examination by a qualified healthcare professional. The appearance is often distinctive, with a waxy or “stuck-on” look and well-defined borders. If there is any uncertainty, a biopsy may be performed and the tissue sent for histopathology to confirm the diagnosis. Professional assessment is important to distinguish seborrheic keratosis from melanoma or other skin cancers.
What are the treatment options for seborrheic keratosis?
Different clinics offer different treatment options, such as cryotherapy, laser treatment, shave removal or curettage, and surgical excision. At Waverley Park Minor Surgery Clinic, seborrheic keratoses are treated using careful surgical excision under local anaesthetic.
Is seborrheic keratosis cancerous or precancerous?
Seborrheic keratoses are benign and are not cancerous or precancerous. They do not develop into skin cancer. However, because some skin cancers can resemble seborrheic keratoses, professional evaluation is essential for any new, changing, or unusual growth.
Do seborrheic keratoses eventually disappear on their own?
In most cases, seborrheic keratoses do not disappear without treatment. Once they develop, they typically persist. They may become thicker or more numerous with age, but spontaneous resolution is uncommon.
Are there over-the-counter products in the UK that can help reduce seborrheic keratosis?
There are currently no clinically proven over-the-counter treatments in the UK that reliably remove seborrheic keratoses. Some topical products claim to reduce their appearance, but results are inconsistent, and they do not remove the lesion completely. Attempting self-treatment can also irritate the skin or delay proper diagnosis. Professional assessment and treatment remain the safest and most effective approach.
