Skin tags and warts are common, benign skin growths that many people seek to have removed for cosmetic reasons or because they cause irritation. While over-the-counter treatments exist, dermatologists possess the medical training and tools to remove them safely and effectively, minimizing the risk of infection, scarring, or recurrence. This article outlines the professional techniques board-certified dermatologists typically employ.
Understanding the Growths: Skin Tags vs. Warts
Before discussing removal, it's crucial to distinguish between these two conditions, as their causes and treatments differ. Skin tags (acrochordons) are soft, small, flesh-colored growths that hang off the skin. They are composed of loose collagen fibers and blood vessels and are not contagious. They commonly appear in skin folds like the neck, armpits, and groin. Warts, on the other hand, are caused by various strains of the human papillomavirus (HPV). They are contagious and can have a rough, grainy appearance. Common types include plantar warts on the feet and flat warts on the face.
Professional Removal Methods for Skin Tags
Dermatologists often remove skin tags during a quick office visit. The chosen method depends on the tag's size, location, and number.
- Cryotherapy: This involves applying liquid nitrogen to freeze the skin tag. The frozen tissue dies and falls off within days to weeks.
- Snipping (Excision): For smaller tags, a dermatologist may use sterile surgical scissors or a scalpel to simply cut it off. This is often preceded by a local anesthetic to numb the area.
- Cauterization (Electrosurgery): An electric current is used to burn off the skin tag. This method also seals blood vessels, minimizing bleeding.
- Ligation: For larger tags, a dermatologist may tie off the base with surgical thread to cut off its blood supply, causing it to eventually wither and fall off.
Professional Removal Methods for Warts
Wart removal can be more challenging than removing skin tags, as the goal is to destroy the virus-infected tissue. Dermatologists have several advanced options.
- Cryotherapy: Liquid nitrogen is the most common in-office treatment for warts. The intense cold destroys the affected cells. Multiple treatments spaced a few weeks apart are often necessary, especially for stubborn warts.
- Salicylic Acid Prescriptions: Dermatologists may prescribe a high-concentration salicylic acid solution, which is more potent than over-the-counter versions. It works by peeling away the infected skin layers over time.
- Cantharidin: This is a chemical derived from blister beetles that a dermatologist "paints" onto the wart. It causes a blister to form under the wart, lifting it off the skin so the doctor can later trim away the dead tissue.
- Excision or Curettage: The dermatologist may scrape off the wart with a sharp instrument (curette) or cut it out with a scalpel, often followed by cauterization. This is typically reserved for warts that do not respond to other treatments.
- Laser Treatment: Pulsed dye or CO2 lasers can be used to target and destroy the tiny blood vessels feeding the wart or to vaporize the wart tissue. This is often considered for numerous or recalcitrant warts.
- Immunotherapy: For persistent warts, a dermatologist may use treatments that stimulate the body's own immune system to fight the virus. This can include applying topical agents like diphencyprone (DPCP) or injecting the wart with an antigen.
What to Expect After Professional Removal
Post-procedure care is vital for proper healing. The dermatologist will provide specific instructions, which generally include keeping the area clean and dry, applying an antibiotic ointment, and protecting it from the sun. A small scab or blister may form. It is critical not to pick at the area, as this can lead to scarring or infection. While dermatological procedures significantly reduce the chance of recurrence, especially for warts, new growths can sometimes appear.
Why Consult a Dermatologist?
While skin tags and warts are usually harmless, it is important to have any new or changing skin growth evaluated by a professional. A board-certified dermatologist can provide an accurate diagnosis, ruling out other skin conditions. They perform removals in a sterile environment, ensuring precision and reducing risks. Attempting self-removal with unsterile tools or off-label products can lead to bleeding, infection, significant scarring, or incomplete removal.
For personalized advice and safe, effective treatment options for skin tags or warts, consulting a board-certified dermatologist is the recommended course of action.
