What are skin tags?
Skin tags are small areas of overgrown skin tissue, which stick out from the surface of the skin. They tend to be quite small initially.
Most stay at around 2-3mm, but might grow to protrude quite noticeably, or develop into papilloma, a larger version of a skin tag which can reach 5mm or more. Over time, more skin tags are likely to develop so that the patient has a patch or crop of skin tags.
What causes skin tags?
Unlike warts, there is no viral cause. Skin tags are most commonly caused by friction, where skin rubs against skin or clothing. That’s why they commonly appear in the underarms and groin area or on eyelids. They can also appear in genital areas.
