Most moles are not considered dangerous. Moles, otherwise know as nevus, are irregularly shaped spots or bumps on the skin. Facial moles have no distinguishing characteristics, other than that they are on the face. Moles vary in color, shape and size, ranging from brown to black, and raised to smooth. Moles sometimes appear at birth and are called birthmarks, while others form later in life. On rare occasions, moles become melanomas, characterized by changes in appearance and irregular shape. If a mole on your face or body has changed, contact your physician. You can use herbal preparations as an alternative treatment for facial moles.
