What are Skin Tags?
Skin tags are small, soft, skin-coloured growths on your skin. They're connected to the skin by a small, thin stalk called a peduncle, they can vary in colour and size – from a few millimetres up to 5cm wide.
Skin tags tend to grow in the skin folds, where the skin rubs against itself, such as on the neck, armpits, groin and under the breasts. They can also grow on the eyelids and under the folds of the buttocks.
The skin tags themselves are made of loose collagen fibres and blood vessels surrounded by skin. Collagen is a type of protein found throughout the body.
Both men and women can develop skin tags. They tend to occur in older people and people who are obese or have type 2 diabetes.
Pregnant women may also be more likely to develop skin tags as a result of changes in their hormone levels. Some people develop them for no apparent reason.
Skin tags can look like warts, but skin tags are usually:
Smooth and soft (warts tend to be rougher with an irregular surface)
Knobbly and hang off the skin (warts are usually slightly raised or flat)
Not contagious (warts spread very easily, so a sudden outbreak or cluster of growths is more likely to be warts)
Skin tags do not usually cause any pain or discomfort and are noncancerous.
