what is a skin barnacle
1 Skin barnacles are sometimes referred to as barnacles of aging and are often seen on people who are 50 years old or older. 2  While not all skin barnacles develop into seborrheic keratoses, which are benign skin growth.3  Most of the time, these age induced barnacles indeed develop into this noncancerous benign skin problem. Do not rub or scratch your skin barnacles since this will only cause them to bleed and get infected. 2  If you find that you are tempted to scratch these barnacles before or after you get them treated, try to cover them loosely with a with sterile gauze and bandages.
