What Causes Skin Tags?
Skin tags, also known as acrochordons, are small, benign skin growths. They develop when extra skin cells are produced in the skin's top layers. A primary cause is friction from skin rubbing against skin, clothing, or jewelry.
- Friction: Skin rubbing against skin in areas like armpits, neck, groin, and under breasts is a major factor. This constant irritation stimulates the growth of extra skin cells. [Source: Multiple references including AAD, Cleveland Clinic, NHS, and Healthdirect]
- Genetics: A family history of skin tags increases your risk. [Source: Dermatology Center of Northwest Houston]
- Weight: Overweight and obese individuals tend to have more skin tags due to increased skin-on-skin friction in folds of skin. [Source: Multiple references, including initial provided text].
- Gender: Women are slightly more prone to developing skin tags than men. [Source: Dermatology Center of Northwest Houston]
- Pregnancy: Hormonal changes during pregnancy can also contribute to skin tag formation. [This information is inferred based on overall understanding of hormonal impact on skin].
- Diabetes: While not directly causing skin tags, diabetes is sometimes associated with an increased frequency and size of skin tags. [This is an additional point, not explicitly stated in provided references, but inferred from broader medical knowledge.]
Where Skin Tags Typically Appear:
Skin tags are most commonly found in areas where skin rubs together, such as:
- Armpits
- Neck
- Groin
- Under the breasts
- Eyelids
- Thighs
While the exact cause isn't always known, the above factors significantly increase the likelihood of developing skin tags. It is important to note that skin tags are usually harmless, and while removal is possible, it's generally not medically necessary unless they cause discomfort or irritation.
