Wart Removal Singapore:
How Warts Are Confirmed, Removed and Why They Return

Wart removal Singapore: viral wart, age wart or skin tag

The word wart covers three lesions that have nothing to do with each other, and the removal plan depends on which one is on the skin. Examination separates them quickly; removing an unexamined lesion destroys the information that would have told you.

The warts versus age warts guide covers how the two are told apart in detail, and the seborrhoeic keratosis and skin tags condition pages cover the other two lesions. A flat brown spot that is neither is assessed as a possible mole under the dermatoscope, as described on the mole removal page.

Wart removal methods: cryotherapy, electrosurgery, CO2 laser and topical treatment

Wart removal in Singapore uses the same small set of methods as elsewhere (the skin hub lists the other lesions removed in clinic), and the guideline evidence is clear that none of them is superior for every wart. Each destroys infected tissue while the immune system deals with the virus. The choice is made by site, depth, number, skin type and what has already been tried.

The British Association of Dermatologists guidelines recommend salicylic acid and cryotherapy as first-line options for common warts and reserve destructive methods for warts that persist. At Dr Sin Yong's practice the methods used in clinic are matched to the lesion and the skin, and treatment that belongs with a GP or dermatologist, such as genital warts, warts in someone with lowered immunity and extensive plantar disease, is referred rather than attempted.

“Half the warts I am asked to remove are not warts. The other half will try to come back, and I would rather tell you that before the first freeze than after the third.”

Plantar wart removal Singapore: feet, soles and around the nails

Plantar warts are the stubborn ones, and the reason is mechanical. On a weight-bearing sole the wart is pushed inward rather than outward, so it sits under a cap of callus and reaches deeper than a hand wart of the same age. It can be mistaken for a corn; the difference is that a wart interrupts the skin lines and shows black dots when the surface is pared, while a corn keeps the lines and has a clear central core.

What changes on the sole

• The callus is pared before any treatment, so that cryotherapy or a topical reaches the wart rather than the cap.
• Cycles are repeated whatever the method, because depth and pressure slow clearance; this is explained at the start rather than discovered later.
• Scarring on the sole can be tender for years, so curettage and deep ablation are used sparingly there, and a tender scar is not traded for a wart that could have been treated more conservatively.
• Mosaic plantar warts, a cluster that has merged into a plaque, are treated as a plaque rather than one lesion at a time.
• Anyone with diabetes, poor circulation or numbness in the feet is examined before any destructive treatment and may be referred, because healing on the sole is slower and infection matters more.

Periungual warts

Warts around and under the nail fold are difficult because the tissue is thin, the nail matrix sits underneath, and freezing or cutting too deeply can leave a lasting nail deformity. Treatment there favours precision, which is where controlled CO2 laser ablation or careful electrosurgery is weighed over broad freezing, and nail-biting or picking is addressed because it is the usual way the virus reached the site.

Why warts come back after removal: the recurrence logic

Patients who have had a wart treated two or three times elsewhere often arrive convinced the treatment was done badly. Usually it was not. The explanation is biological.

• Virus persists in normal-looking skin. HPV infects skin cells around the visible wart, not just inside it. Any method that destroys the visible lesion leaves infected cells at the margin, and a new wart can grow from them.
• Clearance is immune, not surgical. A wart resolves when the immune system recognises the infected cells. Destructive treatment helps that recognition along by exposing infected tissue, which is one reason a wart that has been treated sometimes clears from a site that was not touched.
• Re-inoculation is common. Shaving over a wart, biting nails, picking, and walking barefoot on shared wet floors all seed new sites. Removing the wart without changing the habit invites the next one.
• Some warts are not warts. A seborrhoeic keratosis that was frozen as a wart will keep returning because it was never viral and was never fully removed. This is the commonest reason a wart on a face in the fifties keeps coming back.

So the plan at Dr Sin Yong's practice is written with recurrence in mind: the lesion is confirmed, the method is chosen for the site, repeat cycles are planned rather than promised away, and the habits that spread the virus are named. The warts guide explains the biology in more depth.

What happens at a wart removal visit, and aftercare

The visit

1. The lesion is examined, with magnification where needed, and confirmed as a viral wart, an age wart, a skin tag or something that needs a diagnosis first. Anything bleeding without provocation, growing quickly, ulcerating or irregular is examined rather than removed by assumption.
2. Site, depth, number, skin type and previous treatment are recorded, and the method is chosen with you. For some warts the plan begins with a topical and a review rather than a procedure.
3. Procedural methods are done under local anaesthesia by Dr Sin Yong, who performs every treatment personally after assessment. Plantar warts are pared first.
4. Recurrence, the likely need for repeat cycles, and the habits that spread the virus are discussed before you leave, and a review is set to judge the response.

Aftercare in broad terms

• After cryotherapy a blister forms and settles; it is left intact where possible and kept clean.
• After electrosurgery, curettage or CO2 laser a small crust forms and detaches on its own; it is kept clean and moisturised and is not picked.
• Sun protection on exposed sites matters in Singapore's skin types, because a dark mark after a procedure is the main cosmetic risk; the PIH page explains why.
• Towels, razors and nail clippers are not shared, and feet are covered on shared wet floors while warts are active.
• Increasing pain, spreading redness or pus is reported promptly.

What decides the plan and the fee

The number and site of the warts, the method chosen, whether treatment is staged in cycles, and whether topical treatment is used alongside. Fees are set out at consultation; a figure quoted before examination would not reflect the lesion. Enquiries on WhatsApp are answered in English and Chinese.
