Warts are small skin growths caused by the Human Papillomavirus (HPV). While most are harmless and often go away on their own within a year or two, many people choose to remove them if they are painful, spreading, or a cosmetic concern
1. At-Home Treatments
If you have a common wart on your hand or a plantar wart on your foot, you can often start with over-the-counter (OTC) options.
-
Salicylic Acid (Best Evidence): This is the most effective OTC method. It works by gradually dissolving the wart’s layers.
-
How to use: Soak the wart in warm water for 5–10 minutes, gently file the surface with a disposable emery board or pumice stone, apply the acid, and cover with a bandage. Repeat daily.
-
-
Duct Tape: Known as “duct tape occlusion therapy.” You cover the wart for about 6 days, then soak and file it. While scientific evidence is mixed, it is a low-risk option often used alongside salicylic acid.
-
OTC Freezing Kits: These use a mixture of dimethyl ether and propane to “freeze” the wart. They aren’t as cold or deep-reaching as a doctor’s liquid nitrogen, but can work for small, new warts.
2. Professional Medical Treatments
If home remedies fail after several weeks, a dermatologist can offer more intensive options:
| Method | How it Works | Best For |
| Cryotherapy | Uses liquid nitrogen to freeze the wart, causing a blister to form and the wart to fall off. | Common and plantar warts. |
| Cantharidin | A “beetle juice” extract applied by a doctor that creates a painless blister under the wart. | Children or sensitive skin. |
| Electrosurgery | Burning the wart with an electric needle; often combined with scraping (curettage). | Stubborn or large warts. |
| Laser Therapy | Uses intense light to destroy the wart’s blood vessels or tissue. | Warts that haven’t responded to other treatments. |
| Immunotherapy | Injections or creams that trigger your own immune system to attack the HPV virus. | Clusters or recurring warts. |
3. When to See a Doctor
You should skip the home remedies and see a professional immediately if:
-
The wart is on your face, genitals, or inside your mouth.
-
You have diabetes or poor circulation (home treatments can cause dangerous ulcers or infections).
-
The growth is bleeding, itching, or changing color.
-
You aren’t 100% sure it’s a wart (some skin cancers can look similar).
-
You have a weakened immune system.
