Mr. Onur Gilleard
Qualifications & Experience
Mr Onur Gilleard is a distinguished consultant plastic surgeon on the GMC specialist register. He previously held an NHS consultant post at St Bartholomew’s Hospital in London, specialising in skin cancer and microsurgical reconstruction. In 2021, Mr Gilleard transitioned from the NHS to dedicate himself fully to private practice, allowing him to focus exclusively on providing personalised, high-quality care to his patients. He is recognised as an expert in laser treatments, having conducted research and developed advanced treatment protocols using cutting-edge laser technology to optimise both clinical outcomes and cosmetic results.

Does wart removal leave a scar? Usually not a significant one — Mr Gilleard’s significant-scar rate is under 5%. It depends mostly on the method: conservative CO2 laser carries the least scarring, surgical excision leaves a fine linear scar, and cryotherapy can leave permanent pale patches — one reason we rarely use freezing. This guide explains why scars form, which method scars least, the aftercare that genuinely helps (keep it moist, don’t pick, strict SPF), and how existing wart scars can be improved.
Do Warts Leave Scars?
Usually not a scar worth worrying about. Any procedure that removes tissue carries some risk, but with careful technique it’s small — Mr Gilleard’s significant-scar rate is under 5%. Whether you’re left with a mark, and how noticeable it is, depends mostly on three things: the method used, your skin type (darker skin and a keloid tendency raise the risk), and the aftercare. The good news is that all three can be managed, and the method with the lowest scarring risk — conservative CO2 laser — is also our usual choice for warts and verrucas.
Which Method Scars Least
The removal method is the biggest single factor. Ranked by scarring risk, lowest first:
| Method | Scarring risk | Typical mark |
|---|---|---|
| CO2 laser (conservative) | Lowest | Temporary redness for a few weeks; usually no lasting scar. |
| Curettage & cautery | Low–moderate | A small round mark that fades. |
| Surgical excision | Moderate | A fine linear scar — usually neat, but a definite line. |
| Cryotherapy (freezing) | Variable | Can leave permanent pale patches (hypopigmentation), especially in darker skin — a key reason we rarely use it. |
This is why method choice matters so much on visible or weight-bearing areas: for a facial wart or a sole verruca we favour conservative CO2 laser precisely because it clears the wart while protecting the surrounding skin. The full method comparison is in our wart & verruca removal guide.
Why Some Removals Scar
A scar forms when deeper skin (the dermis) is damaged and the body lays down collagen to repair it. Several things push the risk up: a deep or large wart that needs more extensive removal; a skin type prone to keloid or pigment change; an aggressive method when a gentler one would do; and — very commonly — poor aftercare, such as picking at the healing site, letting it dry-scab, or exposing it to the sun. The last group is the one entirely within your control, and it makes a real difference.
Aftercare That Genuinely Prevents Scarring
Beyond choosing the right method, the aftercare that actually works is simple and evidence-based:
- Keep the wound moist, not dry — a little Vaseline rather than letting a hard scab form. Moist healing scars less than dry scabbing.
- Don’t pick or scratch the healing site — picking is one of the biggest avoidable causes of scarring, and it can spread the wart virus too.
- Strict sun protection once healed — new scar tissue burns and darkens easily, so SPF 30+ on the area for several months prevents lasting pigment marks.
- Silicone gel once the wound has fully closed can help flatten and soften a developing scar, applied over several weeks.
- Avoid stretching or straining the area in the first couple of weeks (heavy exercise, swimming, saunas).
These same steps are covered in our wart removal aftercare guide.
Treating an Existing Wart Scar
If you already have a mark from a previous removal, it can usually be improved. For minor scars, consistent silicone gel or sheets plus gentle massage over a few months is the sensible first step. For hyperpigmented (darkened) scars, sun protection is essential and ingredients such as hydroquinone, vitamin C or retinoids can fade discolouration. Raised hypertrophic scars or keloids respond to corticosteroid injections that flatten the tissue, sometimes over several sessions. Most wart scars fade considerably over 6–12 months and mature by around 12–18 months; even older scars can be improved, though complete erasure isn’t always possible. If scarring is a particular concern for you, raise it at the consultation before treatment so the gentlest suitable method is chosen.
When to Seek Help
See a clinician if a scar stays red, raised or tight beyond three months, restricts movement near a joint, causes persistent pain or itch, or changes unusually (rapid growth, bleeding or ulceration — rarely, skin cancers can arise in scar tissue). Early intervention, while a scar is still remodelling in the first 12–18 months, tends to give the best result.
What People Ask on Reddit — A Surgeon’s Honest Take
The scar threads share the same worries. Here’s the honest version.
“Will freezing my wart leave a white mark?”
It can. Cryotherapy is the method most likely to leave a permanent pale patch, particularly in darker skin — which is one of the reasons we rarely use it and prefer conservative CO2 laser.
“I picked the scab and now there’s a scar — did I ruin it?”
Picking is one of the commonest avoidable causes of scarring, but a fresh scar can still be improved with silicone gel, sun protection and time. Leave healing sites alone and keep them moist.
“Is a laser scar better than cutting it out?”
For most warts, yes — conservative CO2 laser leaves the least mark, while excision leaves a fine but definite linear scar. The right choice still depends on the wart’s size and site.
Your Questions, Answered
- Will wart removal definitely leave a scar?
- No. The significant-scar rate here is under 5%. Conservative CO2 laser and careful technique often leave no lasting scar, especially with good aftercare. Some risk exists with any method that affects deeper skin, but for most people it’s minimal.
- Which wart removal method leaves the least scarring?
- Conservative CO2 laser carries the lowest scarring risk, which is why we favour it for facial warts and verrucas. Surgical excision leaves a fine linear scar, and cryotherapy can leave permanent pale patches — a reason we rarely freeze warts.
- What’s the best way to avoid a scar on the face?
- On the face we use low-power CO2 laser or fine cautery rather than freezing, work conservatively, and advise strict SPF for three months afterwards; in darker skin a test area and sometimes hydroquinone reduce the risk of pigment change. Never use over-the-counter acid or freezing kits on facial skin.
- How long do wart removal scars take to fade?
- Most improve significantly within 6–12 months and mature by around 12–18 months, gradually flattening and fading. Sun protection and silicone gel speed and improve the result.
- Can I prevent scarring after having a wart removed?
- Largely, yes: choose the right method, keep the wound moist rather than dry-scabbing, don’t pick it, protect it from the sun, and use silicone gel once it’s closed. These steps make a real difference to the final appearance.
- Can an existing wart scar be improved?
- Usually yes. Silicone gel and massage help minor scars; hyperpigmentation responds to sun protection and fading agents; raised scars respond to corticosteroid injections. Even older scars can be improved, though complete erasure isn’t always possible.
