What is a Skin Tag?
A skin tag (acrochordon) is a small, benign growth of excess skin that typically hangs from a thin stalk called a peduncle. Skin tags are extremely common—affecting about 50% of adults at some point in their lives.
Key characteristics of skin tags:
- Soft, fleshy, and smooth texture
- Skin-colored or slightly darker
- Hang from a thin stalk (peduncle)
- Usually 2-5mm, but can grow larger
- Painless unless irritated
- Not contagious
Skin tags develop due to friction (skin rubbing against skin or clothing), genetic predisposition, hormonal changes (pregnancy, menopause), weight gain, and age. They're more common after age 40.
What is a Wart?
A wart is a rough, bumpy growth caused by the human papillomavirus (HPV). Unlike skin tags, warts are contagious and can spread through direct contact or contaminated surfaces. There are over 100 types of HPV, and different types cause warts in different body areas.
Key characteristics of warts:
- Rough, bumpy, or grainy texture
- May have tiny black dots (clotted capillaries)
- Flat or dome-shaped—no stalk
- Skin-colored, grey, or brownish
- Caused by HPV virus
- Contagious—can spread by contact
Warts are more common in children and young adults, though anyone can get them. They often appear on hands (common warts), feet (plantar warts), face (flat warts), and genital areas (genital warts).
The Easiest Way to Tell Them Apart
If It's a Skin Tag:
- Hangs from a thin stalk
- Feels soft and smooth when touched
- Located in a friction area (neck, armpit)
- No black dots or rough texture
If It's a Wart:
- Sits flat on the skin, no stalk
- Feels rough or bumpy when touched
- On hands, feet, or face
- May have tiny black dots (blood vessels)
