These small bumps on face not being pimples can either of the following: It occurs when the pores on the skin become blocked with oil, dead skin, or bacteria since the follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto the skin. A zit appears when bacteria grow in a clogged pore and the oil is unable to escape. They are raised bumps on the skin caused by the human papillomavirus (HPV).
They are generally not dangerous, they are ugly, potentially embarrassing, contagious, and they can be painful.
