Seborrheic keratosis (SK) is a common, non-cancerous skin growth that looks waxy, rough or “stuck on”, and usually appears after age 40. It does not need treatment, but many people choose removal when it catches, itches or bothers them. The DOC removes SK in Ashburton and Hoppers Crossing after a skin assessment.
What is seborrheic keratosis?
Seborrheic keratoses (also spelt seborrhoeic keratoses, and sometimes called age warts or brown warts) are benign, wart-like growths on the skin.1 They range from light tan to very dark brown or black, often have a rough or waxy surface, and look as if they have been stuck on like a barnacle. They can appear anywhere except the palms and soles, and are common on the face, chest, back and scalp.1,2
They are extremely common. SKs usually start to appear in a person’s 30s or 40s, and more than 90% of adults over 60 are estimated to have at least one.2 The exact cause is unknown, but they are linked to normal skin ageing and some people inherit a tendency to develop many.1,2 For a full overview of symptoms and causes, see our seborrheic keratosis condition guide.
Seborrheic keratosis vs moles vs warts: what’s the difference?
SKs are often mistaken for moles or warts. The table below shows the usual differences, but appearance alone is not a reliable way to diagnose a skin growth.
Seborrheic keratosis vs mole vs wart
| Feature | Seborrheic keratosis | Mole | Wart |
|---|---|---|---|
| Appearance | Raised, “stuck on”, tan to black1 | Brown or skin-coloured spot or bump3 | Rough, cauliflower-like, often with tiny black dots4 |
| Texture | Waxy, rough or crumbly | Usually smooth | Hard and rough4 |
| Cause | Linked to skin ageing; exact cause unknown1 | A cluster of pigment cells (melanocytes)3 | Human papillomavirus (HPV) infection4 |
| Contagious? | No | No | Yes, by skin contact4 |
| Typical age | Usually after 401 | Most appear in childhood and early adulthood3 | Most common in school-aged children4 |
| Cancer risk | Benign and not pre-cancerous, but can look like skin cancer2 | Usually benign; some can change into melanoma3 | Benign |
| When to check | Very dark, irregular, changing or growing fast1 | New after 25, or changing in size, shape or colour3,5 | Unsure of diagnosis, painful, or not clearing |

SKs are also closely related to dermatosis papulosa nigra (DPN), where many small SK-like spots appear on the face and neck.1 DPN is most common in people with darker skin. Read more in our DPN guide.
Is seborrheic keratosis dangerous?
No. SKs are benign and are not pre-cancerous.2 They do not cause major health problems, although they can itch, catch on clothing or jewellery, bleed if scratched and become inflamed.1 The main concern is that some skin cancers, including melanoma, can look similar, so any uncertain or changing growth should be checked before it is removed.1,2
When a growth should be checked first: see a doctor before any removal if a spot is new (especially after age 25), changing in size, shape or colour, very dark or irregular, growing quickly, bleeding or weeping, or a sore that does not heal.1,5 Suspicious lesions are not treated cosmetically at The DOC; they are tested first.
Seborrheic keratosis removal options compared
The best method depends on the size, thickness, number and location of your SKs, your skin type, and whether a sample needs to be tested.
Removal methods at a glance
| Method | How it works | Sessions | Healing time | Scarring and pigment risk | From price | At The DOC? |
|---|---|---|---|---|---|---|
| Radiofrequency | Radiofrequency energy gently vaporises the growth under local anaesthetic | Usually one per lesion; several lesions in one visit | Crust lifts in about 1 to 2 weeks; pinkness fades over 2 to 12 months6 | Low, but not zero; darkening possible in deeper skin tones6 | $495 first lesion; $195 each extra6 | Yes |
| Laser | Ablative laser removes the growth layer by layer | One or more | Temporary redness and sensitivity; varies | Possible lightening or darkening | $495 per visit6 | Yes, for selected lesions |
| Cryotherapy | Liquid nitrogen freezes thinner growths so they fall off2 | One, sometimes repeated2 | Blister and crust, usually settling within a few weeks | Lightening, especially in darker skin2 | Quoted at consultation | Yes |
| Shave or excision | The growth is shaved, scraped or cut out, and can be sent for testing2 | One | Scab or stitches for 1 to 2 weeks | Small mark or scar | Quoted after assessment; Medicare rebate usually available for biopsy6 | Yes, when testing is needed |
Sources: DermNet,2 The DOC price list and treatment pages (October 2026).6 All removal methods carry some risk of permanent colour change or scarring, and removal does not stop new SKs forming.1
Radiofrequency is a very good fit for most SKs, because they sit on the surface of the skin and can usually be flattened with minimal depth. It destroys the tissue, though, so nothing can be sent to a laboratory. If there is any doubt about the diagnosis, Dr Ed will recommend a shave or excisional biopsy instead.

How much does seborrheic keratosis removal cost in Melbourne?
Keloid treatment prices at The DOC
- Radiofrequency removal: from $495 for the first lesion, plus from $195 for each additional lesion in the same visit*
- Special areas (nose, ears, eye area, genital area): from $695 for the first lesion*
- Laser removal: from $495 per visit*
- Consultation: $195 to $295, charged separately; a Medicare rebate usually applies to the consultation*
Removal of SK for cosmetic reasons is not covered by Medicare or private health insurance. Under the Medicare Benefits Schedule, treatment of seborrheic keratoses is generally paid on an attendance basis,7 which means a rebate may apply to the consultation but there is no separate rebate for the removal itself. Where a biopsy is needed to rule out skin cancer, a Medicare rebate is usually available for that procedure. Full pricing is on our cosmetic mole and skin lesion removal prices page.
*Prices as published on The DOC’s price list and radiofrequency treatment page, October 2026. Final prices depend on size, location and number of lesions and are confirmed at consultation.
What to expect: before, during and after removal
- Before: Dr Ed examines each growth with a dermatoscope to confirm it is an SK. Anything uncertain is tested rather than removed cosmetically.
- During: the area is numbed with local anaesthetic, which stings for a few seconds. Most radiofrequency removals take minutes, and several lesions can often be treated in one visit.6
- After: a dressing is applied. A crust forms over the first week or so and lifts on its own, leaving pink skin that fades over the following months. Daily SPF 50+ sunscreen helps the area heal evenly.6
New SKs may still appear over time, as removal does not prevent new ones from forming.1 Many patients book a review every year or two to treat new spots as they come up.
Frequently asked questions
What is the best way to remove seborrheic keratosis?
There is no single best method. Radiofrequency suits most raised SKs, cryotherapy can suit thinner ones, and a shave or excision is used when the growth needs to be tested. The choice depends on the lesion, its location and your skin type.
Is seborrheic keratosis removal covered by Medicare?
Cosmetic removal is not covered. Medicare generally pays for SK treatment on an attendance basis,7 so a rebate may apply to your consultation, and a rebate is usually available for a biopsy if one is needed.
Does seborrheic keratosis go away on its own?
Rarely. SKs tend to persist, although individual lesions occasionally fade, particularly if they were inflamed.2
Will seborrheic keratosis come back after removal?
A treated SK does not usually return in the same spot, but new ones can develop elsewhere over time.1
Is seborrheic keratosis the same as a mole?
No. A mole is a cluster of pigment cells, while an SK is a growth of the outer skin layer. They can look alike, which is why an examination comes first.1,3
Can seborrheic keratosis turn into skin cancer?
SKs are not pre-cancerous. Rarely, a skin cancer can develop next to or within one, or be mistaken for one, so changing or unusual spots should always be checked.2
