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.
In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals like whales, dolphins, and porpoises which appear to be hairless. The skin interfaces with the environment and is the first line of defense from external factors.
