Skin tags are incredibly common, but if you’ve recently noticed a small flap of skin under your arm, on your neck, or near your groin, you may be wondering: “What causes skin tags — and should I worry?”
Most skin tags are completely harmless, but they can be irritating, cosmetically bothersome, or even linked to underlying factors like friction, genetics, or metabolic conditions. Before deciding whether to remove them, it’s helpful to understand why they form, who gets them, what they look like, and when it’s worth seeing a dermatologist.
This guide breaks everything down simply, starting with the most important question: What causes skin tags in the first place?
Skin tags form when skin rubs against skin or clothing, which triggers extra growth of the outer skin layers.
Several factors increase your chances of developing them:
Friction: Common in the neck, underarms, groin, eyelids, or under the breasts.
Genetics: Some people are simply more prone to them.
Age: More common after age 40.
Insulin Resistance & Metabolic Syndrome: People with prediabetes or diabetes tend to develop more skin tags.
Weight changes: More skin folds = more friction.
Pregnancy: Hormones may play a role.
Skin tags are a common skin condition, affecting nearly 46% of the population at some point in their lives. These small, benign growths are found on various parts of the body, especially in areas where skin rubs together, such as the neck, armpits, and groin. Despite their frequency, many people may not notice them unless they become irritated or are located in a highly visible area. Their widespread occurrence underscores the importance of understanding skin tags and their management, as they are a common concern brought to dermatologists.
While skin tags can occur at any age, they are more prevalent among middle-aged and elderly individuals. This increased incidence in older adults may be due to changes in skin elasticity and the cumulative effects of skin friction over time. However, skin tags can and do appear in younger individuals as well, particularly in those who are overweight or have a family history of skin tags. This age-related trend highlights the importance of regular skin checks and consultations with dermatologists, especially for those in higher age brackets.
Some studies suggest a higher number of skin tags may be associated with insulin resistance — a condition where the body has difficulty processing sugar efficiently. This doesn’t mean skin tags automatically signal diabetes, but it may be worth discussing metabolic screening with your healthcare provider if you have multiple or rapidly increasing skin tags.
Skin tags have been linked to several health conditions, including insulin resistance, obesity, and metabolic syndrome. These associations suggest that skin tags may be more than just a cosmetic issue and could potentially serve as markers for underlying health conditions. For instance, insulin resistance, a precursor to type 2 diabetes, has been frequently observed in individuals with numerous skin tags. Despite these associations, it's important to note that skin tags can also develop in people without these conditions, indicating that multiple factors, including genetics and skin friction, play a role in their formation.
Skin tags, although harmless, can be removed for cosmetic reasons or if they cause discomfort. Before choosing a treatment method, it's important to consult with a qualified dermatologist to ensure the skin tag is benign and to select the most appropriate removal technique. While some methods can be performed at home, professional treatments are generally safer and more effective.
