As the name suggests, skin tags are small pieces of thick skin tied to the skin of your body. So, what causes skin tags? They are caused by groups of collagen and blood vessels that are trapped within a thicker portion of skin. They often appear on the skin and seem to be hanging on it.
The good thing about skin tags is that they are usually harmless skin extensions. They appear on the face, near the lids, under the armpits, in the chest area, and even in the groin area. Generally, they are of the same color as the skin around them. Sometimes they are dark pigmented.
