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.
