Warts are a common and frustrating skin concern that can affect confidence, whether they appear on the hands, feet, face, or more private areas. Many people mistake a wart for a callus or thickened skin and try to pick, scratch, or cut it off themselves — this is dangerous and can cause the wart to spread and grow larger.
Today, ProDerma Aesthetic Clinics takes a closer look at what warts really are, how they spread, the different types, and which medical treatments can remove them safely and completely — so if you’re searching for reliable wart removal in Bangkok, you’re in the right place.
What Is a Wart? What Really Causes It?
A wart is a type of skin condition caused by infection with the HPV (Human Papillomavirus) — not the “papova” virus as it was once classified, since the viral family has since been medically reclassified.
When your skin is infected with this virus, it stimulates the outermost layer of skin cells to thicken and grow abnormally, forming a firm raised bump with a rough surface. It often has a “root,” or tiny black dots underneath — those dots are actually the small blood vessels that feed the wart.
Warts can appear anywhere on the body. Medically, they are classified into 4 main types based on their appearance and location.
1. Common Wart
- Appearance: A firm, raised bump with a clearly rough surface. May be gray, skin-colored, or dark brown, ranging from small to medium in size.
- Commonly found on: Fingers, hands, elbows, and knees.
2. Plane Wart
This type of wart appears as small, firm bumps with a smooth surface — unlike common warts, which have a rougher texture.
Commonly found on: the back of the hands, shins, and forehead.
3. Plantar Wart
Appears as a thick, hardened, flattened growth, larger than a common wart.
Commonly found on: the sole of the foot.
4. Genital Wart
This type appears in the genital area and is a sexually transmitted infection. It usually looks similar to a cauliflower and appears around the genitals and anus.
How Do Warts Spread? Why Does Picking Make Them Worse?
Warts spread easily through direct contact.
- Contact with others: If your skin has an abrasion, a wound, or is damp, and it comes into direct contact with someone else’s wart — or you share items such as towels or shoes — the HPV virus can enter your skin immediately.
- Self-spreading (auto-inoculation): This is very important! Many people, when they first notice a wart, feel frustrated and try to pick, scratch, cut it with nail scissors, or pull it out themselves. Doing this spreads the virus to nearby areas — a single wart can quickly multiply into 10–20 warts.
Who is more at risk of getting warts? Warts can affect anyone at any age, but they are especially common in children and teenagers, as well as people with weaker immune systems or who frequently have skin wounds.
🩺 Medical Wart Treatment: What's the Best Option?
At ProDerma Aesthetic Clinics, our team of board-certified dermatologists evaluates each case to select the most suitable, least painful treatment for every patient. Our standard, effective treatment options include:
1. Topical Medication
Best suited for small, early-stage warts or warts in children. A mild acid-based medication (such as salicylic acid) is used to gradually exfoliate and break down the wart tissue.
- Limitation: Requires consistent, long-term use and may not be suitable for large or deeply rooted warts.
2. Cryotherapy (Liquid Nitrogen)
One of the most popular medical treatments. The doctor applies extremely cold liquid nitrogen directly to the wart, freezing the wart cells so they harden and naturally peel away.
- Advantages: Minimal pain, easy aftercare, no large scarring. Usually repeated every 2–4 weeks until the wart is fully gone.
An innovative, highly precise laser technology that targets and destroys the wart and its root with pinpoint accuracy.
- Advantages: Excellent, fast results — can remove even deep-rooted warts in a single session. The doctor applies topical or injectable anesthesia beforehand, so patients feel no pain during treatment. A small scab remains for about 1 week afterward, and water should be avoided, making it less ideal for areas like the limbs or areas covered by clothing.
4. Surgical Excision
A minor surgical procedure to cut out the wart and its root entirely. This method is less commonly used today, as it tends to leave a larger wound and carries a higher risk of scarring compared to other methods.
⚡ The 2 Most Popular Treatments: CO2 Laser vs. Liquid Nitrogen — Which Is Right for You?
To fully treat warts and prevent them from coming back, ProDerma Aesthetic Clinics’ dermatology specialists primarily use 2 highly effective techniques with proven results:
1. CO2 Laser Treatment
“Solve the problem in one session — precise and fast”
This method uses a highly precise, focused laser beam to destroy the wart tissue, including the root that lies deep beneath the skin.
- Treatment process: The doctor first applies topical or injectable anesthesia so the patient feels no pain during the laser treatment. The CO2 laser then removes the wart layer by layer down to the root.
- Results: The wart is removed immediately in a single session. A small scab forms for about 1 week afterward, and the doctor provides an antibiotic ointment to help the wound heal quickly without scarring.
- Best for: Large warts, deeply rooted warts, or anyone who wants fast results in just one treatment.
2. Liquid Nitrogen (Cryotherapy)
“Gentle, easy aftercare, no anesthesia needed”
An innovative treatment using extremely cold vapor at temperatures as low as -196°C, applied directly to the wart to freeze the wart cells so they gradually shrink and fall off on their own.
- Treatment process: The doctor uses a specialized applicator to apply the cold vapor directly to the wart. Patients feel a cold, tingling sensation during treatment, with no anesthesia or injection required — it is quick and convenient.
- Results: The wart dries out and gradually falls off within 1–2 weeks, with no open wound. Patients can get the area wet and return to daily activities immediately. Treatment is usually repeated every 2–4 weeks until the wart is completely gone.
- Best for: Plantar warts (no discomfort while walking), warts in children, or anyone who prefers to avoid anesthesia injections.
📊 Comparison Table to Help You Decide
| Comparison | CO2 Laser | Liquid Nitrogen (Cryotherapy) |
|---|---|---|
| Sensation During Treatment | Requires topical or injectable anesthesia | Mild cold, tingling sensation (no anesthesia needed) |
| Number of Sessions | May see results in a single session | Repeated every 2–4 weeks (until fully gone) |
| Appearance After Treatment | Small open wound with a dry scab for about 1 week | No open wound; may form a small clear blister that dries on its own |
| Aftercare | Avoid water for the first 24 hours; apply medication as directed | No special care needed; can get wet immediately; avoid picking at the area |

Frequently Asked Questions
Is wart removal painful?
It depends on the method. With CO2 laser treatment, the doctor applies topical or injectable anesthesia beforehand, so you won’t feel pain during the procedure — only a small scab remains for about a week afterward. With liquid nitrogen (cryotherapy), no anesthesia is needed at all; you’ll only feel a mild cold, tingling sensation as the wart freezes.
How many treatment sessions will I need to fully remove a wart?
CO2 laser can often remove the wart, including its root, in a single session — making it ideal if you want fast, one-time results. Liquid nitrogen typically requires repeat sessions every 2–4 weeks until the wart has completely shrunk and fallen off, since it works gradually rather than removing the wart immediately.
Will wart removal leave a scar?
When performed by a board-certified dermatologist with proper technique, both methods are designed to minimize scarring. CO2 laser leaves a small dry scab for about a week that heals with the help of an antibiotic ointment, while cryotherapy leaves no open wound at all — at most a small clear blister that dries on its own — making it the lower-risk option for visible scarring.
Can a wart come back after treatment, or spread to other areas?
Yes, it’s possible if the root isn’t fully treated or if the underlying HPV infection isn’t addressed — this is also why picking, scratching, or cutting a wart yourself is strongly discouraged, as it can spread the virus and multiply a single wart into 10–20 new ones. Seeing a dermatologist for a proper evaluation and treatment plan tailored to the wart’s location, depth, and size gives the best chance of preventing recurrence.
Which is better for me — CO2 laser or liquid nitrogen?
CO2 laser is best for large or deep-rooted warts, or if you want the fastest possible result in one visit. Liquid nitrogen is gentler, requires no anesthesia, and is especially suitable for plantar warts (since there’s no open wound to cause discomfort while walking), for children, or for anyone who prefers to avoid injections. A dermatologist at ProDerma can recommend the right option after examining your specific case.
