Why Skin Tags Love Friction Zones
Skin tags (acrochordons) are small, soft, flesh-colored growths that hang from the skin by a thin stalk. They most commonly appear in areas where skin rubs against skin or clothing—which is why the neck, armpits, and groin are the top three locations.
The constant friction causes irritation and overgrowth of skin cells, leading to these harmless but sometimes annoying growths. Other contributing factors include:
- Obesity – More skin folds = more friction
- Hormonal changes – Pregnancy, menopause, and insulin resistance
- Genetics – If your parents have skin tags, you're more likely to develop them
- Age – More common after 40
- Type 2 diabetes – Associated with higher skin tag prevalence

Safe Removal Options
Skin tags in friction areas can become irritated, painful, or bleed if they get caught on clothing or jewelry. If you want them removed, see a dermatologist for safe options:
- Cryotherapy – Freezing with liquid nitrogen
- Electrosurgery – Burning off with electric current
- Surgical excision – Cutting off with sterile scissors or scalpel
- Ligation – Tying off blood supply (medical setting only)
Warning: Never attempt to remove skin tags at home by cutting, tying off with thread, or using unproven products. This can lead to infection, bleeding, and scarring—especially in sensitive areas like the groin.

- A skin tag changes color, shape, or size
- It bleeds, oozes, or becomes painful
- You develop many skin tags suddenly
