Sebaceous Cyst Removal in London: Cost, Procedure and Recovery

What a Sebaceous Cyst Is

“Sebaceous cyst” is the everyday name for a small, benign sac that forms under the skin and slowly fills with soft, cheesy keratin. Most are actually epidermoid cysts (anywhere on the body, often the face, neck, chest or back) or pilar cysts (usually on the scalp). They are harmless, but they can grow, catch on clothing, become tender, or occasionally get infected, which is why many people choose to have one removed. A consultant assesses the lump at the consultation to confirm it is a simple cyst and not something that needs different treatment. You can see what they typically look like in our sebaceous cyst pictures, and the role of the lining is explained in sebaceous cyst capsules.

Why Remove It, and Why Drainage Is Not Enough

A cyst will not usually disappear on its own. The single most important thing to understand about removal is the capsule. The cyst is a sac, and the only way to stop it coming back is to remove that sac intact, including its entire lining. If a cyst is simply squeezed or drained, the contents come out but the lining stays behind, and the lining can regenerate the cyst, so it recurs. This is the key difference between a quick drainage and a proper surgical excision, and it is why we recommend excision for a lasting result. The full comparison is in cyst drainage vs surgical removal, and why home squeezing and “natural” remedies fail is covered in what does not shrink a cyst.

The Removal Procedure, Step by Step

Cyst removal is a minor surgical procedure done under local anaesthetic. On the day:

1. Assessment and marking: the surgeon examines and marks the cyst, planning the smallest incision that still lets the whole sac be removed.
2. Local anaesthetic: a small injection numbs the area completely; you stay awake and comfortable throughout.
3. Excision of the whole cyst: the surgeon removes the cyst together with its capsule, taking care to lift out the lining intact so nothing is left behind to regrow.
4. Layered closure: the wound is closed with sutures to support healing and give the neatest possible scar.
5. Histology only if needed: the cyst is not routinely sent to the laboratory. It is sent only if it looks unusual during removal, for example a solid appearance, areas of necrosis, increased blood supply or attachment to the deeper tissue. Where histology is done there is a £180 charge.
6. Aftercare and suture removal: you go home the same day with aftercare instructions and a date to return for suture removal, at 7 to 9 days for a cyst on the face and 14 to 18 days for one on the body or scalp.

It is normally a same-day, walk-in walk-out procedure under local anaesthetic, and several cysts can often be removed in one session — how the same-day service works is explained below. A cyst larger than 5 cm, or a cyst on the face or neck, usually has an ultrasound scan first: the head and neck contain important nerves and blood vessels and these cysts have a wider range of possible diagnoses, so the scan confirms what it is and helps plan the surgery. Very large cysts (over 5 cm) or multiple cysts (more than five) are usually done under general anaesthetic rather than local.

Same-Day Cyst Removal: How “See and Treat” Works

“How quickly can I get a cyst removed?” and “is cyst removal a same-day surgery?” are two of the questions patients ask Google most often, so here is exactly how it works at our clinic. We run a “see and treat” service for the majority of straightforward cysts: you attend for the £100 consultation, the surgeon examines the lump and confirms it is a simple cyst, and — if you are happy to proceed — it can be removed in the same visit, under local anaesthetic, in roughly 20 to 45 minutes. No second appointment, no waiting list. From first phone call to cyst-free, the whole journey is often a matter of days.

There are sensible exceptions: cysts over 5cm and most facial or neck cysts need an ultrasound scan first, actively infected cysts are settled with antibiotics before excision (explained below), and anything diagnostically uncertain is investigated properly rather than rushed. Same-day treatment is offered when it is clinically right — not as a sales promise.

Infected Cysts: Why We Treat the Infection First

If a cyst is acutely infected, red, swollen and painful, the surgeon will usually treat the infection before removing the cyst rather than operating straight away. There is a clear surgical reason for this: inflamed, swollen tissue makes it much harder to see and to lift out the cyst capsule completely, and any fragment of lining left behind raises the chance of the cyst coming back. So an acutely infected cyst is typically settled first with oral antibiotics for one week, with the clean excision usually done about 10 days after the antibiotics are started, once the inflammation has settled. This is safer and gives a lower recurrence rate. If you have a hot, painful or rapidly worsening cyst, read our guide to an infected cyst emergency, and the difference from an abscess in cyst vs abscess.

Recovery, Scarring and Aftercare

Recovery is usually quick and straightforward. Most people return to normal activities the same day, with mild tenderness for a day or two. The dressings are splash-proof, and you can shower carefully from the day after the procedure, covering the dressing with cling film and taking care not to soak it. Swimming and exercise can be resumed after two weeks, once the wound is healing as expected. The sutures are removed at the short follow-up, and the scar settles to a fine line over the following months. For the best scar we recommend silicone tape worn at night from about three weeks after the procedure, continued for three months: it hydrates and supports the scar so it heals thin, flat and close to your own skin colour. Good aftercare also lowers the small risk of infection; see aftercare for a clean recovery.

Cysts on the Face, Scalp, Body and Intimate Areas

Cysts can be removed almost anywhere they appear. On the face, the priority is a discreet scar, and the incision is planned along natural skin lines (face and neck cysts usually have an ultrasound scan first, as above). On the scalp, pilar cysts are common and shell out neatly, and we try not to shave any hair. On the body (back, chest), larger cysts are straightforward to excise — back cysts in particular tend to grow larger before patients seek help and often sit deeper, which is why early removal is easier removal. We also remove scrotal cysts, discreetly and under local anaesthetic, at the same £400 fee as any other straightforward cyst. One important caveat: if a cyst is rapidly growing or ulcerated, or otherwise looks suspicious, we do not remove it cosmetically; we refer you to your GP so it can be assessed on the NHS skin-cancer pathway. Beyond skin cysts, we also treat ganglion cysts (£1,000), lip and finger mucous cysts (£400/£900) and dermoid cysts (£1,000) — each with its own dedicated guide.

Can You Get a Cyst Removed on the NHS?

Sometimes — but for most people, realistically, no. Cysts are usually removed on the NHS only when they are causing functional problems — pain, nerve compression or recurrent infections — or when there is a suspicion of cancer. A cyst that is simply unsightly, catching on clothing or slowly growing is classed as cosmetic, and cosmetic removal is not routinely funded. And there is a second hurdle patients discover too late:

This matches what we see in clinic: around 80% of our cyst patients have already seen an NHS GP or dermatologist before coming to us — and were told either that the cyst would not be removed on the NHS, or that the wait would be long. The waiting times patients report to us are typically 6 to 24 months.

One honest piece of advice: see your GP first anyway. Even if the NHS cannot arrange removal, your GP may organise an ultrasound scan that confirms the lump is not cancerous — and that scan is genuinely useful to the surgeon even if you later choose the private route, because it confirms the diagnosis, the size of the cyst and whether it sits near blood vessels.

Who Should Remove Your Cyst: Plastic Surgeon, Dermatologist or GP?

Cyst removal is offered by GPs with minor-surgery services, by some dermatologists and by plastic surgeons — so the question is fair. The practical difference is volume and specialisation: a plastic surgeon’s primary role is operating — removing lesions, reconstructing defects and performing aesthetic surgery — so they are trained in the techniques of complete capsule removal and optimal wound closure, and they know where to place incisions to make them as inconspicuous as possible. GPs and dermatologists may perform minor surgery alongside the many other services they provide, but not at the same scale. At London Skin Clinic every cyst is removed by a GMC-registered Consultant Plastic Surgeon — the same two surgeons who between them perform around 600 cyst excisions a year, which is what keeps our recurrence rate at about 3% and our scars neat.

Your Questions, Answered

Will the cyst come back after removal?

Rarely. At our clinic the recurrence rate is about 3%, because the whole cyst is removed including its capsule. Recurrence happens when the lining is left behind, for example after simple drainage or squeezing, because the lining can regrow the cyst, so excision of the intact sac is the way to prevent it.

Is cyst removal painful?

No. The area is fully numbed with local anaesthetic, so you feel only a brief sting from the injection and nothing during the removal. Most people need no more than simple pain relief for a day or two afterwards.

Can you remove a cyst that is infected?

Usually we treat the infection first. An acutely infected, inflamed cyst is settled with antibiotics so the infection and swelling resolve, because inflamed tissue makes it harder to remove the capsule completely and raises the chance of recurrence. The clean excision is done once it has calmed down.

Will I have a scar?

There is always a fine scar where the cyst is removed, but the incision is kept as small as possible and planned along natural skin lines, especially on the face. Patients are often surprised how neat and small the scar is.

Can several cysts be removed at once?

Yes, often in a single session. The cost is £400 for the first cyst and £250 for each additional cyst, with the full cost confirmed at your consultation.

How much does cyst removal cost?

At London Skin Clinic it is £400 for cyst removal and £250 for each additional cyst, after a £100 consultation. You are given the full cost in writing before anything proceeds.

Is cyst removal free on the NHS?

Only in specific circumstances. The NHS usually removes a cyst only when it causes functional problems — pain, nerve compression or recurrent infections — or when cancer is suspected. Removal for cosmetic reasons is not routinely funded, and even when the NHS agrees, patients report typical waits of 6 to 24 months.

Why won’t the NHS remove my cyst?

Because most cysts are classed as a cosmetic problem rather than a medical one. Unless your cyst is painful, repeatedly infected, pressing on a nerve or diagnostically suspicious, NHS commissioning rules generally exclude it. Around 80% of the cyst patients we see have already been through this conversation with an NHS GP or dermatologist before coming to us.

How quickly can I get a cyst removed?

Often in a single visit. Our “see and treat” service means a straightforward cyst can be assessed and removed in the same appointment, under local anaesthetic, in roughly 20 to 45 minutes. Exceptions are cysts over 5cm and most facial or neck cysts (ultrasound first) and actively infected cysts (antibiotics first, excision around ten days later).

Should a dermatologist or a plastic surgeon remove my cyst?

Both can — the practical difference is surgical volume. A plastic surgeon’s core work is operating, including complete capsule removal and incision placement for the least visible scar. At London Skin Clinic every cyst is removed by a GMC-registered Consultant Plastic Surgeon, across roughly 600 cyst excisions a year, with a recurrence rate of about 3%.
