hi , for about a year now, i keep having these tiny white bumps on my moustache and chin area. these are very small, about 1mm, occasionally a big one will appear, about 5mm. i will use my finger nails to break them and wash the area. when i break these bumps, a white fluid will flow out (like the white stuff from pimples). i thought it was herpes but no sores developed before, and the bumps did not occur on the lips, only on the skin covered area. what could this be? thanks for reading
