There’s no guaranteed way to prevent skin tags, but you can significantly reduce how many you develop by addressing the two biggest triggers: friction and metabolic health. About 20 to 25 percent of people will get skin tags at some point, and most are completely harmless. Still, if you’re prone to them, a few targeted habits can make a real difference.
Why Skin Tags Form in the First Place
Skin tags develop when the body produces extra cells in the top layers of skin. They tend to appear in areas where skin folds and natural movement cause repeated rubbing: the armpits, neck, eyelids, groin, under the breasts, and along the thighs. That constant low-grade friction is the mechanical trigger, but it’s not the whole story.
The other major driver is metabolic. Your body’s ability to regulate insulin plays a surprisingly large role. In a study of 100 obese individuals, 60 percent had skin tags, and those with tags had significantly higher insulin resistance than those without. People with more than 30 skin tags carry roughly a 52 percent risk of eventually developing diabetes. Even having more than five skin tags correlates with meaningfully elevated insulin resistance. So while friction determines where tags appear, your metabolic health often determines how many you get.
Reduce Skin-on-Skin Friction
Since friction is the direct physical cause, anything that minimizes rubbing in skin folds helps prevent new tags from forming. Wearing moisture-wicking fabrics keeps skin drier and reduces the stickiness that increases friction. Applying a light powder or anti-chafing balm to areas like the neck, underarms, and inner thighs creates a barrier that lets skin glide rather than catch.
Clothing and accessories matter too. Tight necklaces, collars, and bra straps that repeatedly rub the same spot can trigger tags in those areas. Switching to smoother fabrics, looser fits, or seamless undergarments removes that constant irritation. If you notice tags clustering in one area, look for what’s rubbing there and change it.
Maintain a Healthy Weight
Carrying extra weight increases skin tags through two pathways at once. First, it creates more and deeper skin folds where friction occurs. Second, excess body fat raises insulin resistance, which independently promotes skin cell overgrowth. Dermatologists at the University of Utah specifically cite weight loss as one of the most effective steps you can take to prevent new tags from forming.
You don’t necessarily need dramatic weight loss to see results. Even a moderate reduction in body fat can shrink skin folds enough to lower friction in problem areas like the neck, groin, and underarms. The metabolic improvements that come with even modest weight loss, including better insulin sensitivity, compound the benefit.
Manage Blood Sugar and Insulin Levels
At least a third of people with diabetes develop skin-related changes linked to their condition, including skin tags. The connection runs through insulin resistance: when your cells don’t respond well to insulin, the excess insulin circulating in your blood stimulates skin cell growth. This is why skin tags are associated not just with diabetes but with the entire cluster of metabolic syndrome, including high blood pressure, elevated cholesterol, and chronic inflammation.
If you’re noticing a growing number of skin tags, it’s worth checking your blood sugar levels. For people already managing diabetes or prediabetes, tighter blood sugar control may slow the development of new tags. A diet lower in refined carbohydrates and added sugars helps keep insulin levels steadier throughout the day, which reduces the hormonal signal that drives excess skin cell production. Regular physical activity improves insulin sensitivity directly, even independent of weight loss.
Hormones You Can’t Fully Control
Pregnancy is a common trigger for new skin tags. The surge in estrogen affects skin cells directly, since pigment and growth cells in the skin carry estrogen receptors. Many women notice new tags appearing during pregnancy that typically don’t go away afterward, though they can be removed cosmetically after delivery. Birth control pills can cause similar changes through the same hormonal mechanism.
Genetics also play a role you can’t modify. If your parents developed skin tags, you’re more likely to as well. This doesn’t mean prevention efforts are pointless. It just means your threshold for developing tags may be lower, so the friction and metabolic strategies above become even more important for you.
What Won’t Work
No topical cream, supplement, or home remedy has been shown to prevent skin tags from forming. Products marketed as skin tag prevention are not backed by clinical evidence. The internet is full of suggestions involving tea tree oil, apple cider vinegar, and similar remedies, but these have no proven effect on preventing new growths. Some may irritate skin enough to cause more problems than they solve, especially near the eyes or genitals.
The strategies that actually work are straightforward: reduce friction in skin folds, keep your weight in a healthy range, and manage your blood sugar. These address the root causes rather than chasing surface-level fixes. If you’re developing large numbers of skin tags, particularly if they seem to be increasing, that pattern itself can be a useful signal worth discussing with your doctor, since it may point to underlying insulin resistance that hasn’t been diagnosed yet.
