Most verrugas (warts) can be removed at home with over-the-counter treatments, though stubborn ones may need professional help. The approach depends on where the wart is, how long you’ve had it, and how it responds to initial treatment. About two-thirds of warts actually disappear on their own within two years, but if yours is painful, spreading, or cosmetically bothersome, you don’t need to wait that out.
Make Sure It’s Actually a Wart
Before you start any removal method, it’s worth confirming what you’re dealing with. Warts are caused by the human papillomavirus (HPV), and they come in a few recognizable forms. Common warts typically appear on the hands as rough, raised bumps, sometimes with tiny black dots (those are dead capillaries, not seeds). Plantar warts grow on the soles of your feet, often flat or pressing inward, and can hurt when you walk. Flat warts are smoother and smaller and can show up almost anywhere.
The concern is that certain skin cancers, particularly a type called amelanotic melanoma, can look remarkably similar to a wart. A key warning sign is irregular pigmentation around the edge of the growth, especially if it’s asymmetric, pink, or has changed over time. If your growth appeared suddenly, doesn’t look like a typical rough wart, bleeds easily, or has uneven coloring at its borders, get it checked by a dermatologist before attempting removal. A biopsy is the only way to rule out something more serious.
Over-the-Counter Salicylic Acid
Salicylic acid is the first-line treatment most people should try. It works by softening and dissolving the thickened skin of the wart layer by layer. You can find it in pharmacies as liquids, gels, patches, or medicated pads in concentrations ranging from about 17% for liquid products up to 40% or higher for adhesive pads. Clinical trials have used concentrations as high as 50% for plantar warts, applied daily for up to eight weeks.
The process takes patience. Here’s what works best:
- Soak first. Soak the wart in warm water for 5 to 10 minutes to soften the skin.
- File down dead tissue. Use a disposable emery board or pumice stone to gently remove the white, dead skin on top. This lets the acid penetrate deeper. Use a separate file for the wart so you don’t spread the virus.
- Apply the acid. Coat only the wart itself, avoiding the healthy skin around it. Petroleum jelly on the surrounding skin can act as a barrier.
- Cover it. Use a bandage or duct tape over the treated area.
- Repeat daily. Most products call for once-daily application. Expect to continue for at least 4 to 8 weeks before the wart is fully gone.
If the surrounding skin becomes very red, raw, or painful, take a break for a day or two before resuming.
The Duct Tape Method
It sounds unusual, but duct tape occlusion therapy has actual clinical evidence behind it. A trial published in JAMA compared duct tape to professional freezing for common warts: 85% of patients in the duct tape group had complete resolution versus 60% in the cryotherapy group.
The technique is simple. Cut a piece of silver duct tape just large enough to cover the wart and leave it on for six days. After six days, remove the tape, soak the area in warm water, and file down the dead skin with a pumice stone or emery board. Leave the wart uncovered overnight, then apply a fresh piece of tape the next morning. Continue this cycle for up to two months. The exact mechanism isn’t fully understood, but it likely works by irritating the skin enough to trigger your immune system to recognize and attack the virus.
Freezing Sprays You Can Buy at Home
Drugstore freezing products use dimethyl ether-propane to freeze the wart at around minus 59°C. That’s considerably warmer than the liquid nitrogen a doctor uses (minus 196°C), but a clinical comparison found no meaningful difference in effectiveness for benign skin lesions when assessed 15 days after treatment. The at-home versions are applied for about 20 to 40 seconds per treatment, depending on the product, and you typically repeat the process every two weeks if the wart persists.
These sprays work best on smaller, common warts on hands and fingers. They’re less effective on thick plantar warts, where the deeper tissue is harder to reach with a milder freeze. You’ll notice a blister form around the wart within a day or two. Leave the blister alone and let it heal naturally. The dead wart tissue should fall off within about 10 to 14 days.
Professional Treatments for Stubborn Warts
If home treatments haven’t worked after two to three months of consistent effort, a dermatologist has stronger options.
Professional cryotherapy with liquid nitrogen is the most common in-office treatment. It’s a quick procedure, usually taking just seconds per wart, but it can sting. You may need multiple sessions spaced two to three weeks apart. Expect a blister and some soreness for a few days afterward.
For warts that resist freezing, doctors may turn to electrosurgery (burning the wart with an electric current) or laser treatment using a CO₂ laser. These are more aggressive and come with trade-offs. A study tracking patients for an average of 10 months after CO₂ laser treatment found that 56% had complete clearance of all treated warts, but side effects were common: post-procedure pain, temporary loss of function in the treated area, and scarring. These methods are generally reserved for recalcitrant warts that haven’t responded to anything else.
Another option for resistant warts is immunotherapy. One approach uses a prescription cream that stimulates your immune system to fight the virus locally. Applied three times per week, it takes a median of about 10 weeks to clear warts, with treatment continuing up to 16 weeks if needed. Your dermatologist might also try injecting a substance directly into the wart to provoke an immune response.
Caring for the Skin After Removal
Once a wart has been treated, whether at home or professionally, the area needs basic wound care. Keep it clean and covered with a bandage for the first few days. Avoid picking at blisters or peeling off scabs, as this slows healing and increases infection risk.
Watch for signs of a secondary infection, which typically develop within three to seven days. These include thick or cloudy discharge from the site, increasing redness that spreads beyond the wound edge, the area feeling hot to the touch, a noticeable odor, or developing a fever above 101°F (38.4°C). If any of these appear, you need medical attention.
Preventing Warts From Coming Back
Wart recurrence is frustrating but common, because removal treatments destroy the visible wart but don’t always eliminate the underlying HPV infection in the skin. A few habits reduce your chances of recurrence and spread:
- Don’t touch or pick at warts. This spreads the virus to other parts of your body and to other people.
- Keep feet dry. HPV thrives in warm, moist environments. Wear sandals in communal showers and pool areas.
- Don’t share personal items. Towels, razors, nail clippers, and socks can all carry the virus.
- Treat early. A new wart is easier to remove when it’s small than after it’s had months to grow and establish itself.
There’s also emerging evidence that the HPV vaccine, originally designed for cancer-causing strains, may help people with stubborn, recurring warts. While the research is still developing, vaccination has shown promise as a treatment option for recalcitrant warts in both immunocompetent and immunocompromised individuals. This isn’t yet standard practice, but it’s worth discussing with a dermatologist if your warts keep coming back despite repeated treatment.
