Skin tags are small, soft, benign growths that hang off the skin. They are extremely common and completely harmless. Along with skin tags, many people develop other minor skin lesions over time — most of which are also benign but can be bothersome or affect confidence.
What Causes Skin Tags?
According to the Mayo Clinic, skin tags are made up of loose collagen fibers and blood vessels surrounded by skin. They commonly appear in areas where skin rubs against skin:
- Neck
- Underarms
- Eyelids
- Groin folds
- Under the breasts
Factors that increase the likelihood of skin tags include:
- Friction — skin rubbing against skin or clothing
- Genetics — they tend to run in families
- Weight gain — more skin folds mean more friction
- Hormonal changes — especially during pregnancy
- Age — more common as we get older
- Insulin resistance or diabetes
Other Common Minor Skin Lesions
Skin tags are just one type of minor lesion. Other common benign lesions include:
- Cherry angiomas — small, round red dots made of blood vessels
- Seborrheic keratosis — waxy, brown, "stuck-on" looking growths
- Sebaceous hyperplasia — enlarged oil glands that look like small doughnuts
- Telangiectasia — visible broken capillaries or "spider veins"
- Milia — tiny white bumps caused by trapped keratin
Are Skin Tags Dangerous?
No. Skin tags and the other minor lesions listed above are benign (not cancer). However, the Cleveland Clinic advises that any new, changing, or unusual growth should be evaluated by a professional to rule out anything more serious before removal.
