See answer. Fordyce spots or granules are present at birth, but which don't become prominent until adulthood. Fordyce spots are small, yellow or white spots that develop in groups on moist tissue such as the lips, in the mouth, tongue, cheeks, female labia, and the penis. You may sometimes find it on the lower lip as well, even though it is rare. They are caused by an overgrowth of the sebaceous glands.
