Unfortunately the NHS considers skin tags – which are small, soft, harmless growths that tend to develop where areas of skin rub together – as cosmetic, and therefore won’t remove them. But you should see your GP if you’re concerned: for example if they’ve changed in size or colour, or they bleed.
There isn’t a specific cause for their formation: they are associated with obesity and diabetes, but genetics and ageing also play a part and they can be more common during pregnancy. People with polycystic ovary syndrome (PCOS) may also be more prone.
