3 days post op Pearl laser treatment I have whiteheads surrounding my mouth, chin and nose. Is this normal?

This is a fairly common side effect from a number of procedures. They are called milia (milium singular from the Latin millet seed) There is nothing to become alarmed about. As the skin heals sometimes the keratin in the pores is plugged up. Aquaphor too, as much as we dermtologists love the stuff, occasionally can cause this occlusion.
It is a simple matter for your physician or aestheteician, to take a small needle or blade and open these up with either forceps or a comedone extractor. Using a Retinoid such as Retin A, Tazarac or Differin will also help. Occasionally, stubborn ones might require a local anesthetic but most of the time this is only slightly uncomfortable and an anesthetic is not needed.
