A wart is a skin infection with human papillomavirus, not just a bump. Medical Director Dr Sin Yong confirms the diagnosis, then plans a short course matched to where the wart is and how long it has been there.
WhatsApp to Enquire →Key facts ↓Warts are a skin infection with human papillomavirus. Removal destroys the visible wart with freezing, radiofrequency, CO2 laser or prescription-strength acids, but virus can remain in nearby skin, so two to four sessions a few weeks apart are common. Plantar warts on the soles of the feet usually take longer than warts on the hands or face.
Common warts are rough, raised bumps on the fingers and hands. Warts around or under the nails are harder to clear because the virus extends under the nail fold.
Plantar warts grow on the soles, where body weight pushes them inward and covers them with thick callus. Tiny black dots inside are clotted capillaries, a useful sign that separates them from corns. Mosaic warts, where many plantar warts merge, take the longest.
Flat warts are small, smooth, slightly raised spots, often in lines on the face, beard area or legs where shaving has spread them. They are treated gently because facial skin, especially Asian skin, can darken after aggressive treatment. Filiform warts are thin projections near the eyes, nose or mouth and are usually removed in one or two sessions.
Paring first. Thick overlying skin is gently pared so treatment reaches the wart rather than the callus above it.
Cryotherapy. Liquid nitrogen freezes the wart, usually in more than one freeze-thaw cycle. A blister forms under the wart and lifts it off over the following week.
Radiofrequency and CO2 laser. Under local anaesthetic, the wart is removed in controlled layers. These suit stubborn warts and those in places where a large freezing blister would be awkward.
Acids at home. A salicylic acid preparation between visits keeps the treated area thin and helps prevent regrowth. Systematic reviews and trials show that clearance with any single method takes time, which is why the plan is a short, structured course rather than one visit.
“A wart is cleared when normal skin lines run back across the spot. Until then, it is still being treated, however flat it looks.”
Some warts are better managed elsewhere or with extra care. Foot warts in people with diabetes or poor circulation are not frozen aggressively. Warts in people on immune-suppressing medicines tend to be more numerous and persistent. Genital warts are assessed separately by a doctor experienced in sexual health. Many warts in young children clear on their own and may simply be watched.
A lesion that bleeds easily, changes quickly, or keeps returning after several rounds of treatment is reassessed rather than treated again by default; Dr Sin Yong will refer to a dermatologist when that is the right step.
Freezing stings and aches for a few minutes and can throb for the rest of the day; on the sole it may make walking tender for a day or two. Paring is not painful because it removes dead skin.
Radiofrequency and laser are done after a small local anaesthetic injection, which stings briefly; after that most people feel pressure only. Very young children are generally not suited to these methods.
Day 0. Examination, paring and treatment. A dressing is applied where needed.
Days 1–3. After freezing, a blister forms and may look dark because of trapped blood; leave it intact. After laser or radiofrequency, a moist crust forms. Keep the area clean.
Week 1. The blister dries and the wart lifts with it. Plantar sites remain tender when walking.
Weeks 2–4. Home acid treatment resumes on healed skin. The next session is usually booked two to four weeks after the first.
Review. Treatment continues until normal skin lines run back across the spot, which is the sign the wart has truly cleared.
Plantar warts, also called verrucae, grow on the soles of the feet. Body weight presses them inwards, so most of the wart sits below a layer of hard callus and walking on it feels like a stone in the shoe. They are among the most common reasons people search for plantar wart removal in Singapore, where barefoot changing rooms, pool decks and humid footwear make spread easy.
Telling a plantar wart from a corn matters, because the treatments are different. After gentle paring, a wart shows tiny black dots and pinpoint bleeding, and the normal skin lines run around it rather than through it. A wart usually hurts more when squeezed from side to side; a corn hurts more with direct pressure. Several warts merged into a patch are called mosaic warts, and these take the longest to clear.
Every visit starts with paring, so treatment reaches the wart rather than the callus above it. Freezing is applied in more than one freeze–thaw cycle, and between visits a salicylic acid preparation is used at home after soaking and filing the area with your own emery board. A large UK trial found freezing and salicylic acid gave similar clearance at twelve weeks, so the choice often depends on comfort and how often you can attend. Stubborn warts can be removed with radiofrequency or CO2 laser under local anaesthetic, keeping depth shallow because a scar on a weight-bearing part of the sole can stay tender.
People with diabetes, numbness in the feet or poor circulation are treated more gently, often with a podiatrist involved, and are not frozen aggressively. For a step-by-step guide, read plantar wart removal in Singapore.
Wear sandals in shared showers, changing rooms and around pools, and cover the wart with a waterproof plaster when swimming. Keep feet dry, change damp socks and let shoes dry out between wears. Use your own towel, emery board and pumice stone, and do not use them on unaffected skin. If someone else at home has warts, treating them at the same time reduces the chance of passing the virus back and forth.
Small hand warts may clear in one or two sessions. Many warts need two to four, spaced two to four weeks apart, and plantar or nail-fold warts can take longer. The number is estimated after examination and reviewed at each visit.
Freezing and acids rarely scar when used correctly. Radiofrequency and laser can leave a small mark or temporary darkening, more so on the face in Asian skin. Depth is controlled to keep marks small, and sun protection helps while the skin settles.
Yes, with care. Facial flat warts are often numerous and are easily spread by shaving or picking. They are treated with gentle settings, sometimes alongside a topical treatment, to limit pigment change in Asian skin. You will also be advised on shaving technique, razor hygiene and skincare to reduce spread while the course is under way.
Yes. They spread by direct contact and from damp surfaces. Keep warts covered at pools and gyms, do not share towels or nail tools, avoid picking, and wear sandals in shared showers to reduce spread to other people and other parts of your body.
Usually after a day or two for hand warts. For plantar warts, avoid long runs or barefoot sport until the blister or crust has settled, which typically takes about a week. Cover the area with a waterproof plaster in the pool and wear sandals in changing rooms. Specific advice is given after each session, depending on the method used.
It depends on the number, size and site of the warts, the method used and how many sessions are needed. Plantar and nail-fold warts often need more visits. IN Eternity Clinic confirms the plan and the cost after examination, before treatment.
A plantar wart interrupts the normal skin lines and, after paring, shows tiny black dots and pinpoint bleeding. It often hurts more when squeezed from the sides. A corn is thickened skin from pressure, has an intact pattern of skin lines and usually hurts with direct pressure. Dr Sin Yong pares the area at the first visit to tell them apart.
The virus can remain in skin around the wart that looks normal, the thick callus can shield the wart from treatment, and reinfection from shoes, floors or family members is common. Regular paring, keeping up home treatment between visits, and continuing until normal skin lines run across the spot all reduce the chance of return.
Occasionally a small, recent wart clears quickly, but most plantar warts need several sessions two to four weeks apart, and mosaic warts take longer. Radiofrequency or laser can remove a stubborn wart in one visit under local anaesthetic, yet follow-up is still needed because virus can persist in the surrounding skin.
If you have diabetes, numbness or poor circulation in your feet, a podiatrist should be involved, and aggressive freezing is avoided. Podiatrists also help with footwear and offloading painful pressure points. For most other people, a doctor can diagnose and treat plantar warts directly, and Dr Sin Yong will suggest podiatry when it adds something.
