skin tags are very common soft harmless lesions that appear to hang off the skin. Skin tags develop in both men and women as they grow older. They are skin coloured or darker and range in size from 1mm to 5cm. They are most often found in the skin folds (neck, armpits, groin). Skin tags are made up of loosely arranged collagen fibres and blood vessels surrounded by a thickened or thinned-out epidermis.
