Hair follicles.: It looks like each bump is at the site of a hair - hair follicle. This would be inflammation called folliculitis. Are they itchy? Try using an astringent such as witch hazel on them and see if they improve. If they are itching or become more in number, or other household members have same, see an M.D.
