Patients regularly walk into the clinic asking about a "skin tag" that turns out to be a wart, or a "wart" that turns out to be a skin tag. The two are often mistaken for each other because they can look similar — small, fleshy growths that protrude from otherwise normal skin. But they are caused by entirely different things, behave differently over time, and require different removal approaches.
Knowing what you actually have helps you decide whether removal is necessary, what method is best, and whether there is anything contagious to worry about.
What Is a Skin Tag?
A skin tag, known medically as an acrochordon, is a small, soft, benign growth of skin tissue. It is usually attached to the body by a thin stalk (a peduncle) that lets it dangle slightly. Skin tags are made of normal skin cells, collagen fibres, and small blood vessels — essentially a loose extension of the surrounding skin.
Common features of skin tags:
- Size: typically 1 to 5 mm, though some can grow larger
- Colour: flesh-coloured, sometimes slightly darker brown, especially in areas with friction
- Texture: soft, smooth, and flexible — they wobble or move when touched
- Location: most commonly in skin folds — neck, armpits, eyelids, under the breasts, groin, and around the waistband area
- Number: can appear singly or in clusters
Skin tags are very common, particularly after the age of 30. They are more frequent in people with diabetes, in those who are overweight, during pregnancy, and in areas of frequent skin-on-skin friction.
What Is a Wart?
A wart is a viral skin infection caused by the human papillomavirus (HPV). The virus enters the skin through small cuts or breaks, infects the surface cells, and causes them to multiply rapidly, producing a thickened, often rough growth.
Common features of warts:
- Size: varies widely from 1 mm to over a centimetre
- Colour: usually pale, grey, or skin-coloured. Often have visible tiny black dots in the centre, which are clotted blood vessels
- Texture: rough, firm, sometimes cauliflower-like surface. Not soft like skin tags
- Location: anywhere on the body, but commonly on hands, feet, fingers, around nails, face, and neck
- Number: can be single or multiple. Sometimes spread by scratching or shaving
Warts are contagious. They can spread to other parts of your own body and to other people through direct contact or shared items like towels and razors.
How Do You Tell Them Apart?
Here is a side-by-side comparison:
| Feature | Skin Tag | Wart | |---|---|---| | Cause | Friction, genetics, hormones | HPV virus | | Texture | Soft, flexible | Rough, firm | | Surface | Smooth | Bumpy or cauliflower-like | | Attachment | Hangs by a thin stalk | Flat-based, sits on skin | | Black dots in centre | No | Often yes | | Contagious | No | Yes | | Spreads to other areas | No | Can spread | | Common locations | Skin folds, eyelids | Hands, feet, face, anywhere | | Pain | Painless | Sometimes painful, especially on feet |
If a growth is soft, smooth, and dangles by a stalk, it is most likely a skin tag. If it is rough, firm, and flat against the skin — especially with little black dots — it is most likely a wart.
That said, some warts (like filiform warts on the face or eyelids) can look elongated and finger-like, mimicking skin tags. A dermatologist can confirm with a quick visual examination, sometimes assisted by a dermatoscope.
Are They Dangerous?
Both skin tags and warts are benign, meaning they are not cancerous and rarely cause serious health problems. However, there are reasons to consider removal:
When to Remove a Skin Tag
- Cosmetic concerns — visible tags on the face, neck, or eyelids
- Friction or irritation — tags that catch on jewellery, clothing, razors, or rub against skin folds
- Bleeding from accidental injury — tags that have been caught and bled repeatedly
- Diagnostic uncertainty — when a growth's identity is unclear and removal allows for examination
Skin tags do not turn into anything dangerous. Removal is usually elective.
When to Remove a Wart
- Pain or discomfort — particularly plantar warts on the soles of the feet, which hurt when walking
- Spread risk — warts can multiply and spread to other body parts or to other people
- Cosmetic concerns — facial warts and warts on visible areas
- Persistent or recurrent warts that have not responded to over-the-counter treatments
- Genital warts — these always require medical attention
Warts sometimes resolve on their own as the immune system clears the virus, but this can take months or years and is unpredictable. Active treatment shortens the timeline and reduces the risk of spread.
How Are Skin Tags Removed?
Skin tag removal is straightforward and quick:
- Cauterisation — a fine electrical probe burns the base of the tag, sealing it off and removing it. The most common method for small to medium tags
- Snip excision — for tags with a clear stalk, a sterile blade removes the tag at the base. Quick and effective
- Cryotherapy — liquid nitrogen freezes the tag, causing it to fall off after a few days. Less commonly used for skin tags than for warts
- CO2 laser — for delicate areas like eyelids or for multiple tags, the laser provides precision and minimal bleeding
Sessions are usually short — 10 to 20 minutes for several tags. Topical numbing cream or local anaesthetic injection is used so the procedure is not painful. Healing is fast, with small scabs that fall off within a week.
Once removed, a tag does not grow back in the same spot. New tags may appear elsewhere over time, but that is a separate event.
How Are Warts Removed?
Wart treatment requires a different approach because the underlying virus needs to be addressed, not just the visible growth:
- Cryotherapy — liquid nitrogen is applied to freeze the wart. Often the first-line treatment. Multiple sessions spaced 2 to 3 weeks apart may be needed
- Cauterisation or electrosurgery — burns away the wart tissue. Effective but requires careful aftercare
- CO2 laser — for stubborn warts, multiple warts, or warts in delicate areas. The laser destroys the infected tissue precisely
- Topical applications — prescription medications like salicylic acid in higher concentrations, imiquimod, or other antiviral preparations
- Intralesional injection — for resistant warts, injection of medication into the wart can stimulate an immune response that clears the virus
Recurrence is more common with warts than with skin tags because the virus can persist in surrounding tissue. A dermatologist may recommend a combination approach to reduce recurrence risk.
Why You Should Not Try Home Removal
Both skin tags and warts have a long history of home remedies — tying threads around tags, applying garlic or apple cider vinegar to warts, using over-the-counter wart paints. These methods carry real risks:
- Infection — unsterile cutting or burning at home is a common cause of bacterial skin infections that need antibiotics
- Scarring — improper technique often leaves more visible scars than the original growth
- Misdiagnosis — what looks like a wart or skin tag could occasionally be something else: a cyst, a mole that has changed, or rarely, a skin cancer. A dermatologist can spot the difference
- Spreading the wart virus — improper home removal of a wart can spread HPV to surrounding skin and to other people
- Eye injury — eyelid tag removal at home is particularly dangerous
Clinic removal takes minutes and avoids all of these risks.
When to See a Dermatologist Urgently
Most skin tags and warts can be addressed at a regular consultation. However, see a dermatologist sooner if:
- A growth has changed colour, size, or shape suddenly
- It bleeds without any obvious injury
- It is itchy, painful, or inflamed
- A wart appears in the genital area
- You have a weakened immune system and develop new growths
These features can occasionally indicate something more serious that needs evaluation rather than simple removal.
Frequently Asked Questions
Q: Will removing a skin tag or wart leave a scar? A: When removed properly by a dermatologist, scarring is usually minimal — a small flat mark that fades over weeks to months. Larger growths or those in high-tension areas may leave more visible marks. Home removal carries a much higher scarring risk.
Q: Can warts spread from one person to another? A: Yes. HPV is contagious and can spread through direct skin contact or shared items like towels, razors, and shoes (for foot warts). Skin tags, on the other hand, are not contagious at all.
Q: How long does the procedure take to remove multiple skin tags or warts? A: A single session typically takes 15 to 30 minutes for several growths, depending on the number and location. Healing time varies from a few days for small tags to a week or two for larger warts. A dermatologist can give you a specific timeline based on the size and number of growths.
