In short
- Warts and verrucas are harmless growths caused by a common virus, and most clear on their own without treatment, though it can take months or up to about 2 years.
- Treatment is usually only worthwhile if a wart is painful, spreading or bothering you; salicylic acid has the best evidence and freezing is the other common option.
- Treatments are often slow and need persistence, and warts can come back because the virus remains in the skin.
- A wart that bleeds, grows quickly, changes, or appears in an adult on the face or genitals should be checked by a doctor rather than just treated.

What is wart and verruca treatment?
Warts are small, rough lumps on the skin caused by a common virus (the human papillomavirus, HPV). A verruca is simply a wart on the sole of the foot, which often looks flatter and can be uncomfortable to stand on. They are harmless and very common.
Most warts and verrucas eventually go away on their own without any treatment, as the body's immune system clears the virus, though this can take months or even a couple of years. Because of this, treatment is usually only worthwhile if a wart is painful, spreading, in an awkward place, or bothering you.
The main treatments are salicylic acid (a paint, gel or plaster used at home over weeks) and cryotherapy (freezing with liquid nitrogen at a clinic). Neither is guaranteed to work, both can be slow, and warts can come back because the virus stays in the skin.
This guide explains the options, what to expect, and when a wart should be checked rather than just treated. It is not a substitute for advice from a pharmacist, GP or specialist.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Salicylic acid vs freezing
| Point | Salicylic acid | Freezing (cryotherapy) |
|---|---|---|
| Where | At home | At a clinic |
| How often | Daily for weeks | Every few weeks |
| Evidence | Best of the simple treatments | Works for some, similar overall |
| Discomfort | Mild | Cold, stinging, can blister |
Both can be slow and neither always works. They are sometimes combined. A wart that is changing or bleeding should be checked rather than treated blindly.
Preparing for your procedure
- Check it really is a wart or verruca; if you are unsure, ask a pharmacist, GP or podiatrist before treating it.
- Decide whether treatment is worthwhile — a usually not painful wart that does not bother you can often be left alone.
- If using salicylic acid, plan to apply it daily for several weeks and to file the surface gently between applications.
- Tell a clinician if you have diabetes or poor circulation, especially before treating a verruca on the foot.
- Be aware that warts are mildly contagious, so avoid sharing towels and cover verrucas at swimming pools.
- Ask how long treatment usually takes and how likely it is to work.
What happens
If you use salicylic acid at home, you usually soak and gently file the wart, then apply the paint, gel or plaster, repeating most days for several weeks. It slowly wears away the wart's surface; stopping too soon is the main reason it fails.
If you have freezing at a clinic, liquid nitrogen is applied to the wart for a few seconds, often more than once in a visit. It feels cold and stinging, and the area may blister and scab over the following days. Freezing is usually repeated every few weeks until the wart clears.
A podiatrist may treat a troublesome verruca by paring it down and using stronger preparations or other techniques. Whichever treatment is used, warts often need several weeks or months of treatment and may still come back.
Is this procedure right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Any lesion that is not clearly a wart, or that bleeds, grows or changes, which should be examined rather than treated.
- Salicylic acid on the face, genitals or over large areas, or on people with diabetes or poor circulation without advice.
- Aggressive treatment of a usually not painful wart that is not bothering anyone, given most clear on their own.
- Warts on the face or genitals of an adult, which need proper assessment first.
Delay or rearrange if…
- You are not sure the lesion is a wart and it needs checking.
- The skin is broken, infected or very sore in the area.
- You have diabetes or poor circulation and have not had foot advice before treating a verruca.
- Your immune system is suppressed and warts are widespread, where specialist input is better than self-treatment.
Alternatives to discuss
- Leaving a harmless wart to clear on its own.
- Salicylic acid as a first-line home treatment.
- Cryotherapy at a clinic, alone or combined with salicylic acid.
- Podiatry treatment for troublesome verrucas.
- Specialist assessment for resistant, changing or widespread lesions.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Can clear or shrink a wart or verruca that is painful or bothering you
- Can ease discomfort from a verruca you stand on
- Salicylic acid can be done cheaply at home without appointments
- May speed up clearance compared with waiting for the wart to go on its own
- Most options are simple and do not need an anaesthetic or surgery
Risks & complications
- Treatment being slow and needing weeks or months of persistence
- The wart not clearing, or coming back later
- Skin irritation, soreness or redness from salicylic acid
- Cold pain, redness, swelling, a blister and a scab from freezing
- Salicylic acid damaging surrounding healthy skin if applied too widely
- A pale or dark mark left after freezing, especially in darker skin
- Wound infection
- Spread of warts to nearby skin despite treatment
- A flat scar, particularly after stronger or surgical treatment
- Numbness if a small nerve near the surface is affected by freezing, mainly on the fingers
- Treating something that was not actually a wart because it was not checked first
The main issues are that treatment is slow, uncertain, and warts can return. Salicylic acid should be kept to the wart itself to avoid damaging surrounding skin. Anyone with diabetes or poor circulation should get advice before treating a foot verruca or using acid preparations. If a 'wart' is bleeding, growing quickly, changing in appearance, or is on the face or genitals of an adult, it should be examined rather than simply treated.
Published figures to discuss
How well wart treatments work varies a great deal between people, between warts, and between studies, and many warts clear on their own regardless of treatment, which makes success rates hard to pin down. For this reason qualitative wording is used rather than invented percentages: salicylic acid has the best evidence among simple treatments, but no treatment reliably works for everyone, and recurrence is common.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Spontaneous clearance | Common over months to years | This is why watchful waiting is reasonable for some warts, especially if treatment would be painful or cosmetically risky. | Topical treatments for skin warts — Cochrane Reviewcochrane.orgSource-linked context |
| Salicylic acid benefit | Modest but evidence-supported; requires consistent use for weeks to months | Poor adherence is a common reason it fails. It is not suitable for all sites or for people with reduced sensation/circulation without advice. | Guide sourcesClinical context |
| Cryotherapy compared with salicylic acid | One primary-care RCT reported 13-week cure rates of 39% with cryotherapy, 24% with salicylic acid and 16% with wait-and-see | Results varied by wart type and setting; plantar verrucae can be especially stubborn. | Topical treatments for skin warts — Cochrane Reviewcochrane.orgPublished figure |
| Pain, blistering, pigment change or scarring after destructive treatment | Pain/blistering are common; scarring is uncommon | Treatment on the sole, around nails and on cosmetically sensitive skin needs extra caution. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is usually no downtime. With salicylic acid the skin may look sore or white where it is applied; with freezing the area reacts like a cold burn over the following days.
- Slow progress over weeks rather than overnight results
- Mild soreness or white-looking skin where salicylic acid is applied
- Redness, a blister and a scab after freezing
- Needing to repeat treatment several times
- The wart sometimes returning after it seems to have gone
Aftercare
- If using salicylic acid, keep applying it daily and file the wart gently between applications, protecting the skin around it.
- Keep a frozen area clean; try not to burst a blister or pick the scab.
- Take simple pain relief such as paracetamol if the area is sore.
- Cover verrucas at swimming pools and avoid sharing towels or socks to reduce spread.
- Avoid scratching or picking warts, which can spread them to other skin.
- Watch for signs of infection and stop and seek advice if the skin becomes very sore or inflamed.
- Go back for advice if there is no improvement after a fair trial, or if the lesion changes.
- Salicylic acid product, plus a pumice or emery board, if treating at home
- A waterproof plaster or verruca sock for swimming
- Simple pain relief such as paracetamol
- A realistic plan for how long to keep treating
- A note of when to seek review
- Pharmacy or clinic contact for questions
Scars and how they heal
Common wart treatments do not usually leave a true scar. Salicylic acid mainly affects the wart itself, though it can sometimes irritate or whiten surrounding skin if overused. Freezing can leave a pale or dark mark, occasionally a small flat scar, and these pigment changes can be more noticeable and longer-lasting in darker skin. Stronger or surgical treatments carry a higher chance of leaving a mark or scar, so are usually reserved for stubborn cases.
⚠ Get urgent help if…
- A 'wart' that bleeds, grows quickly, or changes in colour or shape — get it checked
- Any new growth on the face or genitals of an adult, or a lesion you are unsure about
- Spreading redness, heat, swelling, increasing pain or pus (signs of infection)
- A blister or wound that is not healing after several weeks
- Numbness, tingling or weakness that does not settle, especially in a finger
- Severe pain from a verruca that stops you walking normally
- Warts spreading widely or becoming very numerous, especially if your immune system is suppressed
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

Results & realistic expectations
When treatment works, the wart shrinks and clears and normal skin returns, sometimes after several weeks or months of treatment. Salicylic acid has the best evidence among the simple treatments, but no treatment works for everyone.
Treatment cannot guarantee a wart will clear or never come back, because the virus can persist in the skin. Many warts clear on their own in time regardless of treatment. If a lesion does not behave like a typical wart, or does not respond, it should be reassessed rather than treated indefinitely, partly to make sure it really is a wart.
Warts often clear within months to a couple of years, with or without treatment, but they can recur because the underlying virus remains. Some people get repeated or multiple warts, particularly children and people whose immune system is suppressed. Clearing one wart does not make you immune to getting another.
Related tests, treatments or support
For stubborn warts, salicylic acid used at home between clinic freezing sessions can work better than either treatment alone. For verrucas, a podiatrist may combine paring down the hard skin with other treatments. Your pharmacist, GP or podiatrist can advise on a sensible combination if a single treatment is not working.
Follow-up & long-term care
Much wart treatment is self-directed, so there is often no formal follow-up. With freezing, you may return every few weeks until the wart clears. It is sensible to seek review if there is no progress after a reasonable trial, if the lesion changes, or if you are unsure it is a wart. People with a suppressed immune system, or with warts on the face or genitals, should be assessed by a clinician.
- Keep feet dry and cover verrucas at pools and communal showers to reduce spread.
- Avoid sharing towels, socks or shoes, and do not pick at warts.
- Treat early if a new wart appears and is bothering you.
- Seek advice if warts keep recurring or spreading, especially if your immune system is suppressed.
Repeat, follow-on and what comes next
- Repeat treatment over weeks to months is common, and switching or combining treatments is often needed.
- Warts can return after clearing because the virus persists in the skin.
- A lesion that does not respond should be reassessed to confirm it really is a wart.
- Stronger or surgical treatment is reserved for stubborn cases and carries more risk of scarring.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- Honest advice that treatment is often slow and may not work, with realistic expectations.
- A clear plan for how long to treat and when to seek review.
- A low threshold to reassess any lesion that does not behave like a typical wart.
- Sensible advice to reduce spread, such as covering verrucas and not picking warts.
- A contact route if the skin becomes infected or very sore.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether you treat at home with pharmacy products or pay for clinic treatment
- The number of warts and how many sessions are needed
- Whether the clinician is a GP, dermatologist or podiatrist (for foot verrucas)
- The clinic facility fee and any stronger preparations used
- Follow-up appointments to re-treat stubborn warts
- Any specialist treatment for widespread or resistant warts
- The fee per session and how many sessions are likely
- Whether re-treatment of the same wart is charged again
- Any home products or dressings you will also need to buy
- What happens if the wart does not clear
- Whether assessment to confirm it is a wart is included
- Who to contact if a complication such as infection occurs
On the NHS? Some wart and verruca treatments are available on the NHS when appropriate, but because most warts clear on their own, many practices advise pharmacy treatments or self-care first; private and podiatry treatment is used mainly for stubborn or troublesome warts.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Treating a lesion as a wart without confirming the diagnosis.
- Implying a quick or guaranteed cure when treatment is usually slow and uncertain.
- Not warning that warts can recur after clearing.
- Not mentioning possible skin damage from misused salicylic acid, or pigment change from freezing.
- No plan for what to do if there is no progress.
Marketing red flags
- Offering to remove any 'wart' without examining it.
- Claiming a guaranteed or permanent cure.
- Heavily promoting expensive multi-session courses for warts that often clear on their own.
- No mention of recurrence, scarring or pigment change.
- Treating a changing or bleeding lesion as cosmetic rather than referring it.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Is this definitely a wart or verruca, or should it be examined first?
- Is it worth treating at all, or is it reasonable to leave it?
- Which treatment do you suggest for me, and how long should I give it?
- How likely is it to work, and how likely is it to come back?
- What should make me come back or get it checked again?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my procedure, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this procedure not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
