Effective Treatment for Common, Plantar, and Persistent Warts
Warts are one of the most common skin conditions seen by dermatologists. Although they are usually harmless, they can be painful, spread to other areas of the body, or become difficult to treat without professional care.
At Boise Dermatology & Medspa, we provide personalized wart treatment for both children and adults. Whether you have a common wart on your hand, a painful plantar wart on your foot, or stubborn warts that haven’t responded to over-the-counter treatments, we’ll recommend the most effective treatment plan for your skin.
What Are Warts?
Warts are noncancerous skin growths caused by certain strains of the human papillomavirus (HPV). The virus infects the outer layer of the skin, causing excess skin cells to grow and form a raised bump.
Warts can appear almost anywhere on the body and vary in size, shape, and texture depending on their location.
Although they are benign, warts often persist because the immune system doesn’t always recognize and eliminate the virus.
What Causes Warts?
Warts develop when HPV enters the skin through tiny cuts or breaks in the skin.
The virus is commonly picked up from:
- Locker rooms
- Swimming pool areas
- Public showers
- Shared surfaces
- Direct skin-to-skin contact
Not everyone exposed to HPV develops warts. Genetics, immune response, age, and skin injuries all influence whether someone is more likely to develop them.
Are Warts Contagious?
Yes—but only mildly.
The virus can spread through direct contact with a wart or contaminated surfaces. It can also spread from one area of your own body to another.
To reduce the risk of spreading warts:
- Avoid picking or scratching them.
- Wash your hands after touching a wart.
- Don’t share razors, towels, or nail clippers.
- Wear sandals in public locker rooms and pool areas.
- Keep plantar warts covered when appropriate.
Types of Warts
Common Warts
Common warts usually appear on the hands, fingers, elbows, or knees. They often have a rough, raised surface.
Plantar Warts
Plantar warts develop on the soles of the feet. Because they’re pushed inward by body weight, they can become painful when standing or walking.
Flat Warts
Flat warts are smaller and smoother than common warts and often appear on the face, arms, or legs.
Filiform Warts
Filiform warts are thin, finger-like growths that commonly develop around the eyes, nose, or mouth.
How Are Warts Treated?
Many small warts eventually disappear on their own, although this can take months or even years.
Treatment depends on the size, location, and number of warts, as well as your age and overall health.
At-Home Treatments
Some patients benefit from:
- Salicylic acid wart treatments
- Duct tape therapy
- Gentle filing of thickened skin (as directed)
These methods often work best for small, uncomplicated warts.
In-Office Wart Treatments
Stubborn or painful warts often respond better to professional treatment.
Depending on your needs, treatment may include:
- Cryotherapy (liquid nitrogen freezing)
- Paring or curettage to remove thickened wart tissue
- Combination therapies for resistant warts
Because every wart behaves differently, multiple treatment sessions are often necessary.
Why Do Warts Keep Coming Back?
Unlike many skin conditions, warts are caused by a virus.
Even after a visible wart disappears, HPV may remain in nearby skin until your immune system fully clears the infection. This is why warts sometimes recur or require several treatments before they completely resolve.
Combining at-home care with regular office treatments often provides the highest success rate.
Wart Treatment for Children
Children commonly develop warts, especially on their hands and feet.
Our providers understand that younger patients may be nervous about treatment. Whenever possible, we use gentle techniques designed to minimize discomfort while effectively treating the wart.
We’ll also recommend safe home care to help improve treatment success between visits.
Frequently Asked Questions
Will my wart go away on its own?
Some warts eventually disappear without treatment, but this may take months or even years. Professional treatment often speeds the process and may reduce discomfort and spread.
Are plantar warts different from regular warts?
Yes. Plantar warts develop on the soles of the feet and are often pushed inward by walking, making them painful. They frequently require professional treatment because of their location.
How many treatments will I need?
Many patients require multiple treatments because warts can be stubborn. The number of visits depends on the size, location, and type of wart, as well as how your immune system responds.
Can I cut off a wart myself?
No. Attempting to cut or remove a wart at home can lead to infection, bleeding, scarring, and spread of the virus.
Are warts dangerous?
Most warts are harmless. However, any unusual growth, rapidly changing lesion, or growth that does not respond to treatment should be evaluated by a dermatologist to confirm the diagnosis.
