Common skin tags on the body are not caused by HPV and are not contagious. The concern is understandable because HPV does cause warts, and warts and skin tags can look similar in some locations. But the two are different growths with different mechanisms. This article explains what the science actually shows, where the HPV-and-skin-tag question comes from, and when the location of a lesion warrants a doctor visit rather than at-home treatment.

Key takeaways
Skin tags and HPV are separate conditions with different causes, different structures, and different treatment paths.
- Common skin tags (acrochordons) form from friction and genetics. They are benign and non-contagious.
- HPV causes genital warts, not skin tags. The two look similar in some locations but differ in texture, shape, and origin.
- Research has detected HPV DNA in some skin tag tissue samples. That is not the same as HPV causing the growth.
- If a growth is in the genital region or you cannot confirm its type, see a provider before treating at home.
- For confirmed body skin tags, at-home plasma pen removal is safe, effective, and predictable.
What actually causes skin tags
Skin tags are benign growths of loose connective tissue covered by normal skin. The medical name is acrochordon. They form in skin folds and areas of friction, where skin rubs against skin or clothing repeatedly. Common locations include the neck, underarms, groin, under the breasts, and eyelids.
The established causes are friction, genetics, and metabolic factors like insulin resistance and elevated body mass index. Age also plays a role: most people develop their first skin tags in their 30s and 40s, and the count increases over time. None of these causes are infectious. A skin tag does not spread from person to person. If you have one, you did not get it from contact with anyone.
The American Academy of Dermatology and NIH MedlinePlus both classify skin tags as benign growths with no infectious component in the typical clinical presentation.
The fear behind the question
The question "are skin tags caused by HPV?" usually comes from one of two places. First, the person knows that warts are caused by HPV and has seen something on their skin that resembles both a skin tag and a wart, and they want to know which it is. Second, they found a growth in or near a private area and are concerned it could be a sign of a sexually transmitted infection.
Both concerns are reasonable. Neither is a reason to avoid getting an answer. The honest answer is that the overwhelming majority of skin tags on the body have no connection to HPV. The location concern, though, deserves a direct response.
Skin tags vs. genital warts: what the difference looks like
Genital warts are caused by specific strains of HPV (primarily HPV types 6 and 11) and are the condition most likely to be confused with skin tags in the genital or perianal region. They are not the same growth.
| Feature | Skin tag (acrochordon) | Genital wart (condylomata acuminata) |
|---|---|---|
| Cause | Friction and genetics | Human papillomavirus (HPV) |
| Texture | Smooth, soft, hangs on a narrow stalk | Rough or cauliflower-like surface |
| Contagious | No | Yes (sexually transmitted) |
| Location | Neck, armpits, groin, under breasts, eyelids | Genitals, perianal area, rarely mouth |
| Shape | Pedunculated (stalk-like) | Flat to raised; rarely pedunculated |
| Treatment route | Home removal is appropriate for body tags | Medical evaluation and treatment |
Important: when to see a provider
If a growth is in the genital region, has a cauliflower-like or rough surface, or you are uncertain about its origin, see a dermatologist or healthcare provider before attempting any at-home treatment. The Mayo Clinic and AAD both recommend professional evaluation for any genital lesion of uncertain type.
For skin-tag-like growths in confirmed non-genital friction areas like the armpits, see skin tags in the armpits. For eyelid tags, see skin tags on the eyelids.
What the research actually says
This is where the nuance lives. Some laboratory studies have detected HPV DNA within skin tag tissue samples. A small number of papers have proposed that HPV may play a role in the formation of certain skin tags, particularly in immunocompromised patients.
What this does NOT mean:
- It does not mean skin tags are caused by HPV in the standard clinical sense.
- It does not mean skin tags are contagious.
- It does not mean a typical skin tag on the neck or armpit is a sign of HPV infection.
The detection of HPV DNA in tissue under laboratory conditions is very different from HPV being the causal agent for the growth. Dermatologists do not classify acrochordons (common skin tags) as HPV-related lesions. The clinical and dermatological consensus remains that common skin tags are benign, non-infectious, friction-and-genetics-driven growths.
"HPV DNA found in tissue" and "HPV causes this condition" are two different scientific statements. Only one applies to common skin tags.
When location matters: body tags vs. genital tags
The location of a skin-tag-like growth determines the appropriate next step.
Body tags: safe for at-home treatment
Neck, underarms, back, under the breasts, around the mouth, and eyelid tags are almost certainly acrochordons. At-home treatment is appropriate once you have confirmed they are soft, smooth, stalked, and non-bleeding. Skin tags from friction are common at areas of clothing contact. The skin tags from friction and chafing guide covers the pattern in detail.
Genital or perianal growths: see a provider first
Do not treat at home before seeing a provider. The growth may be a genital wart, a molluscum lesion, or another condition that requires medical management. At-home plasma pen use is not appropriate for lesions that have not been identified.
Lesions with unusual features: evaluate before treating
Any lesion that bleeds spontaneously, changes shape or color rapidly, or appears with other symptoms (unusual discharge, itching, pain in the area) warrants a medical evaluation before any at-home treatment.
Where skin tags fit: benign growths, not viral lesions
Skin tags belong to the benign growth category alongside sebaceous hyperplasia, milia, and dermatosis papulosa nigra. None of these are viral. None are contagious. None require antiviral treatment.
Warts, by contrast, belong to the viral lesion category, caused by HPV strains, and are classified differently in dermatology. The two categories are treated differently and have different implications for the person who has them.
Understanding which category applies to your growth is the first step. For common skin tags on friction areas of the body, you are in the benign growth category. The path forward is identification, then removal if desired.
How to remove skin tags at home once you know what you have
For confirmed, non-genital skin tags, at-home removal is a practical option. The OcuraLife Plasma Pen targets the skin tag at the base with plasma energy, carbonizing the tissue in a focused 5-minute treatment. The steps below cover the process from prep through aftercare.
Prepare and identify
Confirm the growth is soft, smooth, and stalked. It should not bleed on its own or change in appearance. If any of these features are absent, see a provider first. Clean the treatment area with a gentle cleanser and let it dry fully. Apply numbing cream and wait the full time specified on the label if you want to minimize discomfort.
Treat the tag
Set the device to a conservative power level. The OcuraLife Plasma Pen has 9 power settings, so you can match the intensity to the size and location of the tag. Treat the base of the tag with brief, precise contact. The whole treatment for a single tag runs about 5 minutes. Do not press harder or longer to rush the result. Apply healing patches over treated areas that may contact clothing.
Follow the aftercare timeline
Day 1
Treat & scab forms
A few minutes per tag. A small protective scab appears the same day. Healing patches cover friction points.

The bottom line
Common skin tags are not caused by HPV and are not contagious. The research is clear on that clinical point. Some studies have detected HPV DNA in skin tag tissue under laboratory conditions, which is a different statement, and one that does not change the clinical classification or the treatment approach.
The practical guidance: if a growth is on your neck, armpits, back, or another friction-prone area, it is almost certainly a benign skin tag. If a growth is in the genital or perianal area, or if you cannot confirm what it is, see a provider before treating it at home.
For everything outside that boundary, at-home removal is safe and effective once you know what you are dealing with.
