People with type 2 diabetes and insulin resistance get skin tags more often than those without metabolic changes. The relationship is real and has two separate explanations: friction zones where skin folds trap heat and moisture, and elevated insulin and IGF-1 levels that accelerate the kind of fibroblast overgrowth that creates skin tags. Having skin tags does not mean you have diabetes. Having clusters of new skin tags, together with other signs, is worth a conversation with your doctor.

Key takeaways
Elevated insulin and IGF-1 lower the threshold for skin-tag formation. Diabetes does not cause skin tags, but it makes them far more likely in friction zones.
- Friction is the direct mechanical cause. Insulin resistance is the biochemical amplifier.
- Pre-diabetes and obesity both fit the same pattern, often simultaneously.
- Having skin tags does not diagnose diabetes. The combination of new clusters plus other metabolic signs does warrant a blood test.
- Skin tags do not go away when blood sugar improves. Removal is a separate action from treating the cause.
- The OcuraLife Plasma Pen treats skin tags at home regardless of the metabolic context.
Why skin tags and diabetes show up together
Skin tags form when the top layers of skin get caught in a friction zone and the fibroblast cells that build connective tissue overproduce. That is the direct mechanical cause. Most skin tags have nothing to do with blood sugar or metabolism. They are just the body responding to repeated skin-on-skin or skin-on-clothing friction.
The metabolic layer on top of that: insulin and a related growth factor called IGF-1 are both known to stimulate fibroblast proliferation. When circulating insulin is chronically elevated, as it is in insulin resistance and type 2 diabetes, those same fibroblast cells are more active. The skin does not need as much mechanical friction to develop a tag. The threshold is lower. The result is that people with metabolic changes tend to develop more skin tags, especially in the friction zones where the two drivers compound.
This is the mechanism the American Academy of Dermatology and the Mayo Clinic reference when they note the skin tag and diabetes association. For a closer look at the purely mechanical side of this, see skin tags from friction and chafing.
The established triggers
Because "skin tags mean diabetes" is a claim that circulates on social media without nuance, here is the honest evidence split.
| Evidence level | Trigger |
|---|---|
| Established | Skin-on-skin friction (neck folds, armpits, under breasts, groin), age (40+), obesity, family history, insulin resistance, type 2 diabetes, elevated IGF-1. |
| Suspected | Pre-diabetes (impaired fasting glucose) specifically: strong clinical pattern, harder to isolate from obesity and friction overlap. Hormone shifts of pregnancy. |
| Not established | Skin tags as an independent diagnostic marker for diabetes. Skin tags as precancerous (they are benign). Stress or diet as direct skin-tag causes in isolation. |
The key distinction: metabolic changes lower the threshold for skin-tag formation. They are not the only path to getting one.
Type 2 diabetes
People diagnosed with type 2 diabetes show higher skin tag prevalence in published dermatology studies. The proposed pathway is the IGF-1 and insulin signal acting on keratinocytes and fibroblasts in friction zones. The skin tags themselves are harmless. Their frequency is a signal about the metabolic environment, not an independent risk.
Pre-diabetes and insulin resistance
Insulin resistance, even before a type 2 diagnosis, appears in the same pattern. This is clinically relevant because pre-diabetes is often asymptomatic. Women who notice sudden increases in the number of skin tags in their 30s or 40s, particularly in fold zones, are in the group where the question "have you had your blood sugar checked recently?" is worth asking. Not because skin tags diagnose anything, but because the co-occurrence is informative.
Obesity and friction zones
Obesity creates more skin folds and more sustained friction zones. It also, independently, is associated with insulin resistance. The two drivers stack. A woman who has gained significant weight will develop more skin tags from friction alone, and if metabolic changes accompany the weight gain, that adds the biochemical layer. This is why skin tag prevalence in high-BMI populations is substantially higher: both causes are present simultaneously.
Pregnancy-related insulin changes
Pregnancy temporarily alters insulin sensitivity. Some women develop new skin tags during pregnancy for this reason, often in the neck, armpit, and under-breast zones. These typically remain after delivery rather than resolving.
Does having skin tags mean I have diabetes?
No. This is the question most readers arrive with, and the honest answer is no.
Skin tags are extremely common in the general population. Most people who develop them have no metabolic disorder. The association with diabetes is a statistical correlation in the direction of "people with diabetes are more likely to have skin tags," not "people with skin tags are likely to have diabetes." Those are different claims.
What is true: if you are developing new skin tags frequently, in clusters, and in friction zones, and you have other risk factors for type 2 diabetes (family history, weight changes, fatigue, increased thirst, frequent urination), that cluster of signals together is worth a fasting glucose or HbA1c test. The skin tags are not the diagnostic signal. The combination is.
For the related question of whether a viral cause is at play, see skin tags and HPV, which covers that entirely separate question.
Why they cluster: the insulin-resistance mechanism
The "friction only" explanation most search results rely on misses the second driver. The more precise account: friction and insulin resistance run in parallel, not in series.
The friction pathway
Skin folds create warm, moist, persistently rubbing surfaces. The skin responds to chronic friction by overproducing fibroblast tissue, eventually forming a small pedunculated growth. This pathway operates independently of any metabolic factor and explains why almost everyone gets at least one skin tag by middle age.
The IGF-1 pathway
Elevated insulin activates insulin-like growth factor 1 (IGF-1) receptors on both keratinocytes (surface skin cells) and fibroblasts. Chronic activation from prolonged insulin resistance keeps these cells in a state of heightened proliferative activity. The skin in friction zones is already primed to produce tags. The elevated IGF-1 environment means the threshold for crossing into overgrowth is lower. New tags form with less provocation. Existing tags grow slightly faster. The pattern compounds over time, which is why clustering, rather than single isolated tags, is more characteristic of metabolic involvement.
When a cluster of skin tags plus other signs means see your doctor
New skin tags on their own are a normal skin change. New skin tags together with the following is a different conversation. If several of these are happening at the same time, mention it to your primary care doctor or endocrinologist:
See your doctor if you have new skin tags AND
- Dark, velvety skin patches in skin folds, especially the neck, armpits, or groin. This is acanthosis nigricans, and it is a more direct metabolic signal than skin tags.
- Unusual fatigue that is not explained by sleep.
- Increased thirst and frequent urination.
- Blurred vision.
- Slow-healing cuts or sores.
- Unexplained weight changes.
The skin tags by themselves do not earn this visit. The cluster of co-occurring signs does. NIH MedlinePlus covers the broader range of skin changes associated with metabolic conditions.
Friction is the match. Insulin resistance is the fuel. Together they explain why diabetic skin tags cluster where they do.
What to do if you keep getting new skin tags
The practical issue most readers face: the skin tags keep coming back, or new ones keep appearing, even after removing the existing ones. If the underlying metabolic environment has not changed, the skin is still a candidate for more.
Address the root drivers where possible
Weight loss reduces both the friction zones and the insulin-resistance contribution. See skin tags and weight loss for the honest answer on whether losing weight makes existing tags go away (it often does not) and whether it prevents new ones (it reduces frequency). Managing the friction zones is also controllable regardless of metabolic status: dry, breathable clothing in fold zones and reducing sustained skin-on-skin contact reduces tag formation. The skin tags from friction guide covers this in depth.
For the tags that are already there
Skin tags do not resolve on their own in meaningful numbers regardless of metabolic status. Removing the ones you have is a separate action from addressing the cause. Waiting for metabolic improvement before removing existing tags means living with them indefinitely. For a full comparison of removal options, the best at-home skin tag removal guide covers what works and what does not.

The bottom line
The skin tag and diabetes connection is real and mechanistic, not just coincidence. Elevated insulin and IGF-1 lower the threshold for skin-tag formation in friction zones. Pre-diabetes and insulin resistance fit the same pattern. None of that makes skin tags dangerous on their own, and none of it changes the most direct path to clear skin.
If new skin tags are appearing in clusters and you have other metabolic signals, a fasting glucose or HbA1c test is the appropriate next step: not because the skin tags diagnose anything, but because the combination is worth evaluating. For the skin tags themselves, removal is independent of the metabolic question and does not require resolving insulin resistance first.
If any individual tag bleeds spontaneously, grows rapidly, changes color, or has irregular borders, see a dermatologist before treating it yourself. That rule does not change with the metabolic context.
