What Causes Skin Tags? The Real Reasons They Keep Appearing

You noticed a small, soft bump hanging from your skin: around your neck, under your arm, or along your bra line. It is probably a skin tag: a benign growth that has nothing to do with hygiene or infection. Here is exactly why skin tags form, what they may signal, and what safe removal looks like in Malaysia.

Key Takeaway

• Skin tags are benign: not cancer, not contagious, not caused by a virus

• In Malaysia, multiple skin tags may signal insulin resistance: a blood sugar check is worth discussing alongside removal

• At-home removal kits risk scarring on darker skin tones: professional Fotona laser removal is safer and more precise

Why Skin Tags Form: The Causes You Need to Know

Skin tags (medically known as acrochordons) form when extra skin cells accumulate in areas of repeated friction. Five factors drive this: skin-on-skin friction, obesity, insulin resistance and Type 2 diabetes, hormonal changes from pregnancy or PCOS, and age or genetic predisposition.

Cause	Who Is Most at Risk	Body Areas Most Affected
Repeated skin friction	Anyone with skin folds or tight clothing	Neck, armpits, groin, under breasts
Obesity / high BMI	Adults with BMI above 25–30	Armpits, inner thighs, groin
Insulin resistance / Type 2 diabetes	1 in 5 Malaysian adults	Neck and armpits (most common pattern)
Hormonal changes	Pregnant women, women with PCOS	Neck, underarms, abdomen
Age and genetics	Adults 40+; those with a family history	Any friction-prone area

The five primary causes of skin tags and the body areas they most commonly affect.

• Skin friction is the primary trigger, repeated rubbing stimulates abnormal skin cell growth, especially in fold areas. Malaysia's humid climate makes this worse year-round.

• Obesity amplifies both causes at once, a higher BMI increases skin folds and elevates insulin levels simultaneously.

• Insulin resistance elevates IGF-1, a hormone that accelerates cell proliferation in areas already stressed by friction.

• Type 2 diabetes shares the same IGF-1 pathway, which is why multiple tags at the neck and armpits often signal a metabolic health check is worthwhile.

• PCOS, pregnancy, age, and genetics each compound the risk through overlapping hormonal and structural mechanisms.

When Skin Tags May Signal a Health Issue

Multiple skin tags that appear rapidly, especially around the neck and armpits, may indicate elevated insulin levels. In Malaysia, approximately 15.5% of adults have Type 2 diabetes (among the highest rates in Southeast Asia), making this connection clinically meaningful for a large proportion of readers.

Research published in the Indian Journal of Dermatology found significantly higher rates of skin tags in patients with obesity and Type 2 diabetes compared to healthy controls. 

Multiple or rapidly appearing tags in fold areas are worth discussing with your doctor: not to alarm, but to rule out insulin resistance early.

Acanthosis nigricans, characterised by dark, velvety patches in skin folds, is driven by the same insulin-mediated pathway and often appears alongside skin tags. Our article on dark underarms treatment in Malaysia covers this overlap, and our underarm whitening treatment service addresses the cosmetic presentation.

Is It Really a Skin Tag? How to Tell the Difference

Skin tags, warts, and moles can look similar, but they have distinct characteristics. A skin tag is smooth and soft, hanging from a thin stalk. A wart is rough, firm, caused by HPV, and contagious. A mole can, in rare cases, undergo malignant change; any growth with changing features warrants evaluation.

Use the ABCDE rule to quickly check any pigmented growth: Asymmetry, Border irregularity, Colour variation, Diameter above 6mm, and Evolution (any change over time). A skin tag passes all five. If yours does not, see a GP before booking aesthetic removal.

On Fitzpatrick IV–V skin tones (the majority of Malaysian adults), skin tags often appear noticeably darker than surrounding skin due to localised hyperpigmentation in the stalk, making them easy to mistake for moles. 

Professional assessment is significantly more reliable than self-diagnosis. Read our guide on Pico laser safety for darker skin tones for more on laser safety for Malaysian skin.

Feature	Skin Tag	Wart	Mole
Texture	Smooth, soft	Rough, firm	Smooth or slightly textured
Attachment	Thin stalk (pedunculated)	Flat base, firmly attached	Flat or slightly raised, no stalk
Contagious?	No	Yes (HPV)	No
Cancer risk?	None	Very low	Low; malignant change is possible
Colour on Fitzpatrick IV–V skin	Often darker than the surrounding skin	Skin-coloured to brown	Variable; may be multi-toned
Action needed?	Removal optional; professional if in doubt	Medical treatment for HPV	Monitor with ABCDE rule; see GP if changing

Safe Skin Tag Removal in Malaysia: Why the Method Matters

Source: Gangnam Theme Dermatology

For Malaysian skin, laser removal is the safest option. Doctors here use surgical excision, cryotherapy, cauterisation, or laser but for Fitzpatrick IV–V skin tones, laser carries a clear advantage: minimal tissue trauma and a significantly lower risk of post-inflammatory hyperpigmentation (PIH). 

At-home removal kits cannot distinguish between the tag and surrounding skin, making PIH a real risk for darker skin tones.

Fotona Laser Sculpt uses an Er:YAG laser to vaporise tag tissue layer by layer with minimal thermal spread. This makes it precise, low-trauma, and well-suited for Malaysian skin. For a full breakdown of what to expect, read our guide on Fotona Laser Sculpt for benign lumps and bumps.

Most tags are cleared in a single session, a numbing cream is applied, the laser ablates the stalk and tag body, and a small crust resolves within 1–2 weeks with no stitches required. 

A tag fully removed does not typically recur at the same site. Should any PIH develop post-removal, pigmentation removal options are available at Dream Clinic, and our article on removing pigmentation on the face covers aftercare in full.

Our patients trust us not just for the results, but for the care behind them:

FAQs

Q1.  Do skin tags mean I have diabetes?

Not necessarily. Skin tags are associated with insulin resistance, which underlies Type 2 diabetes, but many people with skin tags have no metabolic disorder. 

However, if you are developing multiple skin tags quickly around the neck and armpits, a blood glucose check is a reasonable precaution, especially in Malaysia where Type 2 diabetes affects approximately 1 in 5 adults.

Q2. Can a skin tag turn into cancer?

No. Skin tags are benign and do not become cancerous. However, a growth that bleeds, changes colour rapidly, has an irregular border, or grows quickly should be evaluated by a doctor before any removal is attempted. These features may indicate a different condition requiring medical assessment.

Q3. Is it safe to remove a skin tag at home?

At-home removal kits carry risks of incomplete removal, infection, and scarring. For Malaysian adults with Fitzpatrick IV–V skin tones, there is the additional risk of post-inflammatory hyperpigmentation: persistent dark marks that can follow skin trauma on deeper skin types. 

Professional removal with the Fotona laser is safer and more precise.

Q4. How many sessions does skin tag removal take?

Most skin tags are removed in a single Fotona Laser Sculpt session. A small crust forms at the site and resolves within 1–2 weeks with no stitches required. Multiple skin tags may be addressed in the same session or staged across two visits, depending on the doctor's assessment.
