Warts are common, benign skin growths caused by the Human Papillomavirus (HPV). While they are usually harmless, they can be unsightly, uncomfortable, and highly contagious. Understanding the specific type of wart you have is the first step toward successfully removing it.
The image below illustrates the typical appearance of common warts on the hand:

This guide covers the seven primary types of warts and the most effective methods to get rid of them.
The 7 Types of Warts and How to Identify Them
HPV has over 100 strains, which manifest as different types of warts depending on where they grow and how they look.
1. Common Warts (Verruca vulgaris)
- Appearance: Rough, raised bumps with a distinct “cauliflower” texture. They often contain tiny black dots, which are clotted blood vessels.
- Location: Most frequently found on the hands, fingers, knuckles, and elbows.
2. Plantar Warts (Verruca plantaris)
- Appearance: Flat or hard growths that grow inward rather than outward due to the pressure of walking. They can be painful, feeling like a pebble in your shoe.
- Location: Found exclusively on the soles of the feet.
3. Flat Warts (Verruca plana)
- Appearance: Smooth, flat-topped, and flesh-colored or yellowish bumps. They are smaller than other warts but tend to grow in large clusters (sometimes 20 to 100 at a time).
- Location: Most common on the face, neck, back of the hands, and legs (often spread by shaving).
4. Filiform Warts
- Appearance: Long, narrow, thread-like growths that extend outward from the skin. They grow rapidly.
- Location: Usually appear around the mouth, nose, eyes, or under the chin.
5. Periungual and Subungual Warts
- Appearance: Rough, uneven bumps that look like thickened skin or cauliflower-like clusters. They can distort nail growth and be quite painful.
- Location: Periungual warts grow around the fingernails and toenails, while subungual warts form directly underneath the nail bed.
6. Mosaic Warts
- Appearance: A tightly packed, extensive cluster of many small plantar warts grouped closely together. They look like a rough, white patch of tile across the skin.
- Location: Typically cover larger surface areas on the hands or the soles of the feet.
7. Genital Warts (Condyloma acuminata)
- Appearance: Soft, flesh-colored bumps that can look like small cauliflowers.
- Location: Found in the genital areas. Unlike other types it require immediate professional medical care.
How to Get Rid of Warts: Treatment Options
Warts often disappear on their own over several months or years, but active treatment can speed up the process and prevent them from spreading. Because different treatments work for different people, it is helpful to look at the three most common paths to removal:
1. Over-the-Counter (OTC) Home Remedies
- Salicylic Acid: This is the most common home treatment. Available as liquids, gels, or patches, it works by gradually dissolving the layers of the wart. For best results, soak the wart in warm water and gently file away dead skin with an emery board before applying. Make sure to double-check the physical label to confirm the concentration and application instructions.
- OTC Cryotherapy (Freezing): Retail kits use mixtures of dimethyl ether and propane to freeze the wart tissue. While not as cold as liquid nitrogen used by doctors, it can successfully destroy smaller common or plantar warts.
- Duct Tape Therapy: A popular home remedy involves covering the wart with silver duct tape for six days, soaking and filing the wart, leaving it uncovered overnight, and repeating the cycle for up to two months to stimulate the body’s immune response.
2. Professional Medical Treatments
- Liquid Nitrogen Cryotherapy: A dermatologist applies ultra-cold liquid nitrogen to freeze the wart. This forms a blister underneath the growth, causing the dead tissue to slough off within a week or two. Multiple sessions are often required.
- Cantharidin: A doctor paints this substance (derived from blister beetles) onto the wart. It causes a painless blister to form beneath the growth, lifting the wart off the skin so the doctor can clip away the dead portion.
- Electrosurgery and Curettage: The wart is burned using an electric current and then scraped off with a sharp tool called a curette. This method is highly effective but may cause scarring.
3. Prescription and Advanced Therapies
- Prescription Retinoids: For stubborn or widespread flat warts, a doctor may prescribe topical retinoid creams to disrupt the wart’s skin cell growth.
- Immunotherapy: For severe, treatment-resistant warts, doctors can inject substances like Candida antigen directly into the wart to alert your immune system to fight off the underlying HPV virus.
- Laser Surgery: Pulse-dye lasers can burn closed the tiny blood vessels inside the wart, causing the tissue to die and eventually drop off.
Tips to Prevent Warts from Spreading
Warts are highly contagious and can spread to other parts of your body or to other people through direct contact or shared surfaces.
π Frequently Asked Questions (FAQs)
Q: Can you pop or cut off a wart at home?
A: No, you should never attempt to cut, pop, or rip off a wart yourself. Doing so can cause severe infection, permanent scarring, and cause the Human Papillomavirus (HPV) to spread to surrounding skin, creating even more warts.
Q: Why do some warts have tiny black dots inside them?
A: The small black dots frequently seen in common and plantar warts are not seeds. They are actually clotted blood vessels (capillaries) that the wart has intercepted to supply itself with blood and nutrients.
Q: How long does it take for a wart to completely go away?
A: Without treatment, many warts go away on their own within 1 to 2 years as the body builds an immune response. With active over-the-counter or clinical treatments, removal usually takes anywhere from a few weeks to a couple of months.
