The common benign lesions people ask about
| Lesion | What it is | Usual removal method |
|---|---|---|
| Skin tag (acrochordon) | Soft, stalked skin-coloured growth in folds (neck, armpits, groin, eyelids) | Snip excision or hyfrecation; cryotherapy for tiny ones |
| Seborrhoeic keratosis | “Stuck-on”, waxy, warty brown patch; very common with age | Cryotherapy, curettage or hyfrecation |
| Cherry angioma | Small bright-red dome from a cluster of vessels | Hyfrecation or vascular laser |
| Milia | Tiny hard white cysts, often around the eyes | Fine needle extraction or hyfrecation |
| Dermatosis papulosa nigra | Small dark papules on the face, common in darker skin | Low-setting hyfrecation or gentle cautery, conservatively |
| Sebaceous hyperplasia | Soft yellowish bumps with a central dip | Hyfrecation or light electrocautery |
This list is not for moles or anything pigmented and changing
If a lesion is a mole, is pigmented, or has changed in size, shape, colour or symptoms, it needs a diagnostic assessment first — see the section below. It should not be removed by a destructive method.
Why every lesion is checked before removal
Skin cancers — including melanoma, basal cell carcinoma and squamous cell carcinoma — can resemble harmless lumps and marks. If a lesion is frozen off, burnt off or lasered without first being examined properly, and it turns out to be a skin cancer, the diagnosis is delayed and the record of what it looked like is gone.
A responsible clinic will:
- Examine each lesion with a dermatoscope (a specialist magnifier with polarised light).
- Take a photograph for the records.
- Send anything cut out (shave or excision) for histology as a matter of routine where appropriate.
- Refer urgently, rather than treat, if there is any suspicion of skin cancer.
The removal methods explained
Cryotherapy (freezing)
Liquid nitrogen destroys the lesion by freezing. Quick and good for seborrhoeic keratoses and small skin tags. Causes a blister, then a scab. Can leave a pale mark, especially on darker skin.
Hyfrecation / electrocautery
A fine probe uses heat or a high-frequency current to seal and remove the lesion. Precise and versatile — used for tags, cherry angiomas, milia, sebaceous hyperplasia and thread veins. Local anaesthetic for all but the smallest.
Shave excision & curettage
The lesion is shaved flush with the skin under local anaesthetic; the base may be lightly cauterised. The tissue can be sent to the lab. Good for raised lesions where a diagnosis is wanted.
Snip excision
Stalked skin tags are simply snipped at the base with sterile scissors. Fast, minimal healing.
Laser
Vascular lasers target cherry angiomas and thread veins; ablative lasers can remove some raised lesions. Chosen for specific lesion types and cosmetically sensitive areas.
What a removal appointment is like
- Assessment
Each lesion is examined with dermoscopy, photographed and diagnosed. The method and expected result — including scar risk — are discussed and consented.
- Numbing
A tiny injection of local anaesthetic for all but the smallest lesions. It stings briefly, then the area is numb.
- Removal
Each lesion takes 1–5 minutes. Several can usually be done in one visit.
- Dressing & aftercare
A small dressing and written aftercare. Any tissue removed by shave or excision is sent for histology where indicated, with results in about a week or two.
Healing, scarring and aftercare
- Expect a small scab or crust that heals over 7–14 days; leave it to come away on its own.
- Keep the area clean and moist; follow any ointment/dressing instructions.
- Avoid picking, swimming pools, saunas and heavy exercise for a few days.
- Sun protection on the healing site for 4–6 weeks to reduce pigment change.
- Most sites heal with a flat, pale mark that fades. Raised or keloid-prone areas (chest, shoulders) carry more scar risk — flag this beforehand.
Manage expectations on the face
On facial skin, the aim is “less visible than the lesion, well healed”. A conservative approach over one or two sessions protects against a mark that’s more noticeable than what you started with.
Illustrative time to a healed, settled surface. The residual mark then continues to fade over several weeks to months.

When to see a doctor instead of booking removal
Get an urgent assessment if a lesion
Is a mole that has changed in size, shape or colour; has an irregular border or more than one colour; is itching, bleeding, crusting or not healing; looks different from your other moles (“ugly duckling”); or is a new pigmented spot appearing after age 30. Also see a doctor about any persistent, growing or ulcerated lump. These need diagnosis, not cosmetic removal.

Frequently asked questions
How much does skin tag removal cost in Knightsbridge?
The first lesion is typically £90–£350 in London, with additional lesions at the same visit around £30–£120 each. A separate, often redeemable, consultation fee applies, and histology (when tissue is sent to the lab) is £70–£150 per sample.
Does removal hurt?
A small injection of local anaesthetic stings for a few seconds, then the area is numb and you feel only pressure. Very small lesions can sometimes be treated without anaesthetic. Each lesion takes only a few minutes.
Will it leave a scar?
Most sites heal with a small flat mark that fades over weeks to months. Raised areas like the chest and shoulders, and keloid-prone skin, carry more scar risk — your clinician will discuss this before treating those sites.
Can you remove moles the same way?
No. Moles and any pigmented or changing lesion need a diagnostic assessment first and, if removed, should be excised so the tissue can be examined by a pathologist. Destroying them by freezing or burning risks missing a skin cancer.
How do I know if my lesion is a skin tag or something more serious?
You may not be able to tell — some skin cancers mimic harmless lumps. That’s why every lesion is examined with a dermatoscope before removal, and anything suspicious is referred rather than treated.
How long does healing take?
A small scab or crust forms and usually heals within 7–14 days. Keep the area clean, don’t pick, and protect it from the sun for four to six weeks to reduce the chance of a pale or dark mark.
Why do I keep getting new skin tags?
Friction, weight gain, pregnancy and genetics all contribute. Multiple new skin tags, particularly around the neck and armpits, can also be associated with insulin resistance, so it’s worth mentioning to your GP.
Can several lesions be removed in one appointment?
Usually yes. After assessing each one, most people have several small lesions treated in a single visit, with additional-lesion pricing applied.
Is removal safe on darker skin?
Yes, but the method matters. Cryotherapy and aggressive settings carry a higher risk of pale or dark marks on richly pigmented skin, so gentler, more controlled techniques and conservative dosing are preferred.
Will my GP remove these on the NHS?
The NHS generally only removes benign skin lesions if they’re causing medical problems (repeated bleeding, catching, infection). Removal for cosmetic reasons is usually private.
