About these lesions
Skin tags (acrochordons)
Soft, flesh-coloured or slightly darker outgrowths of skin, usually small (a few millimetres). They tend to occur in skin folds — neck, armpits, groin, under the breasts, eyelids. They’re completely benign but can catch on clothing or jewellery, become irritated, or simply be cosmetically unwelcome. Pregnancy, weight gain, diabetes, and family history are common contributing factors.
Sebaceous cysts (epidermoid cysts)
Soft to firm lumps beneath the skin, often with a small central punctum (visible opening). They form when skin cells get trapped beneath the surface and slowly accumulate keratin (the protein in skin). Common on the scalp, face, neck, back, and behind the ears. Usually painless and slow-growing but can become infected, inflamed, or cosmetically prominent. Discharge of foul-smelling material (sometimes confused with pus) is common when squeezed — not recommended.
Lipomas
Soft, mobile lumps under the skin made of fatty tissue. They feel like a small soft ball that can be moved around freely under the skin. They’re benign tumours of fat cells, slow-growing, and usually painless. Common on the arms, back, shoulders, thighs, and trunk. Most are small but some grow over years to several centimetres.
~1 in 4
UK adults have one or more skin tags, cysts or lipomas. They’re benign in the vast majority of cases — removal is usually for cosmetic or symptom relief.
Reasons for removal
None of these lesions need to be removed for medical reasons in most cases. People typically seek removal for:
- Cosmetic concerns — particularly facial, neck, or visible lesions
- Physical irritation — catching on collars, bras, jewellery, razors
- Recurrent inflammation — cysts that flare or get infected periodically
- Size or growth — lipomas pressing on nerves or causing functional issues
- Discomfort — some cysts and lipomas become tender
- Pressure points — lesions on the waistband, bra strap, scalp
- Uncertainty about diagnosis — removal confirms benign nature on histology
Initial assessment
Before any removal, we conduct a focused clinical assessment:
- Examination — looking at the lesion, location, size, surrounding tissue, and ruling out features that warrant different management (signs of skin cancer; signs of infection; deeper involvement).
- Discussion — cosmetic expectations, scar risk, recovery time, costs, and alternatives.
- Consent — written consent for the specific procedure planned, including potential complications and what histology will be done.
- Planning — for lesions suitable for in-clinic removal, often done at the same visit. For larger or anatomically complex lesions (face, deep lipomas, hands), we may suggest plastic surgery or referral.
When we don’t remove in clinic
Some lesions warrant specialist input rather than in-clinic removal:
• Lesions with any suspicious features (suspected skin cancer) — urgent dermatology referral
• Lipomas larger than ~5cm or in awkward locations (face, hands, near nerves)
• Lesions on the eyelid, lip, or other cosmetically sensitive sites — plastic surgery referral
• Cysts that are actively infected — treat the infection first, then remove later
• Children under a certain age depending on lesion and cooperation
We’ll discuss this with you at consultation.
How removal works
Skin tag removal
Most skin tags are removed by:
- Snip excision — the tag is grasped with forceps and snipped off at the base with sterile scissors. Tiny tags don’t usually need anaesthetic; larger ones get a small injection of local anaesthetic first. Healing is rapid; no stitches needed.
- Cryotherapy — freezing the tag with liquid nitrogen so it falls off over 1–2 weeks. Useful for multiple tags or sensitive areas.
- Electrocautery — using heat to remove the tag and seal the base. Quick; minimal bleeding.
Multiple skin tags can usually be removed in a single appointment.
Sebaceous cyst removal
Proper removal requires excising the entire cyst including its wall — otherwise it recurs. The procedure:
- Local anaesthetic injected around the cyst
- Small elliptical incision over the cyst
- Careful dissection to remove the cyst intact
- Closure with dissolving or non-dissolving stitches depending on location
- Dressing applied
Time: 20–45 minutes depending on size and location. Stitches (if non-dissolving) are removed at 5–14 days depending on the site.
Lipoma removal
Most small to moderate lipomas can be removed in clinic:
- Local anaesthetic
- Incision over the lipoma
- Dissection and delivery of the lipoma (lipomas usually “shell out” cleanly because they have a thin capsule)
- Closure with stitches
- Dressing
Larger lipomas, deep lipomas, or those near important structures (nerves, vessels) may need plastic surgery or general surgery referral.
After the procedure
You walk out the same day. General after-care:
- Keep the dressing clean and dry for 48 hours
- Avoid swimming and prolonged immersion until stitches are out
- Showering is usually fine after 48 hours; pat dry
- Avoid heavy lifting or strenuous exercise for 5–10 days depending on location
- Paracetamol is usually sufficient for any discomfort
- We provide written aftercare instructions and a contact number
- Return for stitch removal at the agreed time (if non-dissolving stitches used)
- Some bruising and swelling around the site is normal for 1–2 weeks
Sending tissue for testing
For most removals where there’s any possibility of underlying pathology, the tissue is sent for histology (microscopic examination). This is standard for:
- Any pigmented lesion
- Any lump that looks atypical
- Anything where the diagnosis isn’t completely certain
For obvious skin tags and uncomplicated lipomas, histology is sometimes not necessary — we discuss this individually. Histology results come back in 7–14 days and we’ll communicate the result to you.
Risks and considerations
All surgical removal carries some risk, even minor procedures:
- Scarring — some mark is inevitable; careful technique minimises but doesn’t eliminate this
- Bleeding — usually minor; tell us if you’re on blood-thinning medication
- Infection — uncommon with good aftercare; signs include increasing pain, redness, swelling, discharge, or fever
- Recurrence — particularly for cysts if the wall isn’t fully excised, or lipomas in some locations
- Keloid or hypertrophic scarring — more common in people with darker skin or family history; we discuss this if relevant
- Nerve damage — rare; only relevant for certain locations
- Numbness at the site, usually temporary
When removal isn’t appropriate
Sometimes the better course is not to remove:
- Active infection — needs antibiotic treatment first
- Cosmetic concern over a small unobtrusive lesion — the scar may end up more visible than the lesion
- Pregnancy — non-urgent removal usually deferred
- Significantly thinned skin (e.g. long-term steroid use)
- Coexisting medical conditions that increase surgical risk — assessment individual
- Lesions in young children — assessment case-by-case
When to see us
Book a consultation if:
- You have one or more skin tags causing irritation or cosmetic concern
- You have a sebaceous cyst that keeps inflaming or is growing
- You have a lipoma you’d like removed
- You have multiple lesions you’d like assessed together
- You want a lesion checked first before deciding on removal
- You have a lump and you’re not sure what it is
Book sooner if a lesion is changing rapidly, bleeding, painful, or has other concerning features — see also our mole / skin lesion concerns page.
Frequently asked questions
How much does it cost?
Current prices are on our Fees page. Costs depend on size, location, and number of lesions. We quote before any procedure.
Can it be done at the first appointment?
For most uncomplicated skin tags, yes. For cysts and lipomas, we usually consult first and book the procedure as a second appointment within a week.
How big a scar will I have?
Depends on lesion size and location. Smaller lesions leave smaller scars. Areas with thinner skin or more tension (chest, shoulders) tend to scar more. We discuss this realistically in consultation.
Will my insurance cover this?
UK PMI policies typically cover removal when there’s clinical suspicion of pathology or when symptoms warrant it (pain, infection, function). Purely cosmetic removals are usually not covered. We provide procedure codes; check directly with your insurer.
Can multiple skin tags be done in one go?
Yes. Multiple skin tags are commonly removed in a single appointment.
Will the lipoma come back?
If completely removed, recurrence is uncommon. Some people are prone to developing new lipomas in other locations — that’s genetic, not failure of the procedure.
Will the cyst come back?
Only if the cyst wall wasn’t fully removed. Careful excision technique reduces this risk significantly.
What if I’m on blood thinners?
Tell us at booking. Many people can still have minor surgery; sometimes we coordinate with your other clinicians. We don’t generally stop blood thinners without consultation with the prescribing doctor.
What about cryotherapy alone for skin tags?
Cryotherapy works for many small skin tags. The tag freezes, then falls off over 1–2 weeks. Sometimes needs a second treatment. Discussed individually.
