What are skin tags?

Skin tags are growths that hang from your skin — your doctor might call them 'acrochordons'. They can be from 1mm to 1cm in size.

Skin tags are made of collagen (a type of protein) and blood vessels surrounded by skin. They usually grow in the folds of your skin, where the skin rubs together, such as in your:

• armpits
• groin
• anus
• thighs
• eyelids
• neck
• under your breasts

Skin tags are common, especially as you age. They happen in about every 1 in 2 adults. They don't cause any harm.

Speak to a doctor about having your skin tag removed if it's bothering you.

What are the symptoms of skin tags?

Most skin tags are painless and don't cause any symptoms. But if they rub on your clothing or jewellery, they may get sore and bleed.

Skin tags have a small stalk that attaches them to your skin. This makes them look different from warts and other skin sores. Warts tend to be flat, while skin tags hang off the skin.

What causes skin tags?

The exact cause of skin tags is not known It's likely to be due to both lifestyle and genetic causes.

You are more likely to get skin tags in areas where the skin tends to rub against itself.

Some health conditions are thought to increase your chance of getting skin tags, such as:

• overweight and obesity
• diabetes
• pregnancy

Anyone of any gender can develop skin tags and they are more common in older people. Skin tags that develop during pregnancy usually disappear after your baby is born.
