The honest answer is yes and no — and the “no” is the part that actually matters for your health. If you have skin tags and you have improved your insulin sensitivity through weight loss, movement, or medication, here is what the research supports: you will likely form fewer new skin tags, and you will have lowered the metabolic risk the tags were pointing to. But the skin tags you already have rarely fall off on their own. To make an existing tag disappear, it has to be physically removed — and removal by itself does nothing about the insulin resistance underneath.
That distinction is the whole point. Skin tags, medically called acrochordons, are a symptom — a visible marker that insulin has been running high (more on that in my earlier piece on what skin tags mean). Treating the marker without treating the cause is mowing the weeds and leaving the roots.
Watch: do skin tags go away if you fix your insulin?
Why does improving insulin stop new skin tags but not old ones?
Because the two are different problems. When insulin runs high, insulin and its close relative IGF-1 act as growth signals on your skin cells. Skin tag tissue is unusually rich in the receptors that catch those signals — one study found significantly higher IGF-1 and IGF-2 receptor expression in skin tag tissue than in normal skin (PMC7640457). Those growth signals prompt the cells to build the small stalk of collagen and blood vessels that becomes a tag.
When you lower insulin, you stop sending the “build” command — so new tags slow down or stop. But the stalk you already built does not un-build itself just because the signal quieted. The signal is reversible. The structure it already created is not. That is the entire reason new tags decline while existing ones stay put.
Are skin tags really linked to insulin resistance?
Yes — the association is well documented, and it strengthens with the number of tags. Skin tags are extremely common, affecting nearly half of adults. But clustering matters: people with more than about five, particularly on the neck, armpits, and groin, show meaningfully higher rates of insulin resistance and metabolic syndrome. Meta-analyses have established skin tags as a cutaneous sign of insulin resistance (Int J Dermatol. 2023;62(12):1500-1507), and a 2025 study found skin tags associated with roughly 1.9 times the odds of diabetes (Cureus. 2025).
The honest framing: this is a consistent association plus a plausible mechanism. Skin tags are a marker of insulin resistance, not proof of a one-way cause. But the association is strong enough that multiple tags are worth treating as a prompt to check your metabolic health.
What actually works — for new tags and for old ones?
Split it cleanly, because the two goals need different tools:
To stop new tags and fix the underlying problem: improve your insulin sensitivity. The bar is lower than most people expect — even a 5–10% weight loss meaningfully improves insulin sensitivity, alongside regular movement and a diet lower in refined carbohydrates and higher in fiber.
To remove the tags you already have: see a qualified professional. Common methods are cryotherapy (freezing), electrocautery (burning), and excision (cutting). This is safe and effective — but understand what it is: a cosmetic procedure. It clears the flag without touching what raised it. Do it if the tags bother you; never let it substitute for the metabolic work.
A note of caution: do not try to cut or tie off skin tags yourself. Removal should be done by a professional to avoid bleeding and infection.
What should you do if you have multiple skin tags?
You do not need to panic — you need data. The most useful step is to have your insulin and metabolic markers measured, not just glucose, which can look normal for years while insulin quietly climbs.
Ask your provider for:
- Fasting insulin
- A1C
- HOMA-IR (calculated from fasting insulin and fasting glucose)
Together these show what the tags on your skin have been hinting at.

Work with Moxie Wellness
At Moxie Wellness, we practice metabolic medicine — evaluating and treating the insulin resistance that skin tags so often flag. If you have multiple skin tags and want a clinician who investigates the metabolic cause rather than just removing the tags, we can help. Moxie is a cash-pay telehealth practice, currently licensed in Florida and Washington, DC.

Frequently asked questions
Will my skin tags disappear if I lose weight?
Weight loss that improves insulin sensitivity tends to reduce the formation of new skin tags, but existing tags usually do not fall off on their own. Removing a tag you already have requires a cosmetic procedure. The metabolic improvement is still worth it — it addresses the underlying risk the tags were signaling.
Does removing a skin tag help my insulin resistance?
No. Removal is purely cosmetic and does nothing to change insulin resistance. Skin tags are a symptom, not a cause. Addressing the underlying insulin resistance through lifestyle change and, when appropriate, medical care is what improves your health.
How many skin tags is too many?
There is no strict threshold, but having more than about five — especially clustered on the neck, armpits, or groin — correlates with higher rates of insulin resistance and metabolic syndrome, and is a reasonable prompt to have your metabolic markers checked.
Are skin tags a sign of diabetes?
They are an associated marker. Studies link multiple skin tags with higher odds of insulin resistance and type 2 diabetes, but a skin tag is not a diagnosis. It is a reason to test — fasting insulin, A1C, and HOMA-IR — not to assume.
What lab tests should I ask for?
Fasting insulin, A1C, and HOMA-IR. Standard checkups often measure only glucose, which can stay normal for years while insulin rises. Measuring insulin directly is what reveals insulin resistance early.
