A verruca is a type of wart caused by the human papillomavirus (HPV). They usually appear on the soles of the feet and can look different from person to person.

A skin tag might be small, but that doesn't mean it's not annoying. Many people don't seek treatment because they're worried about appearance. They seek treatment because they're fed up with it catching on things throughout the day.

Many people contact me because they've noticed a small growth on their skin and want to know whether it's a skin tag. Sometimes it is. Sometimes it isn't. The challenge is that several common skin conditions can look surprisingly similar, especially when viewed online.
