This is where acne is in its initial stage. It starts with whiteheads and blackheads. You can notice a few white spots on your face, especially on the tip of your nose, corners of the nose, and below your lower lip. Basically this happens when your hair follicles get blocked due to dirt, and dead cells. This leads to collection of sebum in the follicles leading to white heads. These do not cause inflammation, and would be noticed only after a close look at your face, especially in these areas.
