Bacteria on skin. Computer artwork of bacteria (green and grey) on human skin. Many types of bacteria are found on human skin, especially associated with sweat glands and hair follicles. They usually cause no problems, although some can cause acne. Bacteria usually only become a problem if they penetrate the skin, for example through a wound or cut.
