Skin tags sometimes look a bit like warts, but they aren't the same thing. They consist of connective tissue and fat cells and usually grow to only a few millimetres in size. They often occur where areas of skin rub together, such as under the armpits, on the neck or even under the breasts. They're usually harmless and don't cause pain.

It's not yet fully understood why skin tags develop. However, certain factors such as genetic predisposition, age and hormonal changes may increase the likelihood that they will appear. 

Don't remove them yourself!

Although they can be unsightly, skin tags aren't usually problematic from a medical point of view. So it's not absolutely necessary to remove them, but many people choose to have them removed for aesthetic reasons. 

You shouldn't attempt to remove a skin tag yourself or try home remedies such as apple cider vinegar, thread or sharp objects. This can lead to inflammation, infection, scarring or unnecessary pain. Only a qualified professional can safely remove skin tags. This usually involves surgical excision, laser treatment or electrocautery. All these are outpatient procedures and generally well tolerated.

Practical tips

• Monitor: Although skin tags are harmless, you should consult a doctor if they grow suddenly, bleed or cause pain.
• Keep skin folds and creases dry: Since skin tags tend to result from rubbing, it helps to keep skin folds and creases dry, especially when it's hot or during exercise.
• Go gently: Aggressive exfoliation or vigorous rubbing can irritate the skin. 
• Have regular skin checks: It's a good idea to have your skin checked occasionally, not just for skin tags.
