An areola tattoo is a cosmetic procedure that is done on the area of the breast or chest where the areola is found. The idea of areola ink is that it alters the appearance of the nipple in some way, be it adding one or changing the shape. Areola tattoos are done in the same manner as other tattoos—by depositing ink under the skin to create a permanent image—but tend to be particularly detailed in regards to blending and feathering, to ensure an extremely natural look.
