Milia, more commonly know as a whitehead, is a ordinary problem. It is easily treated by using a sterile small gauge needle to unroof the lesion followed by extraction of the contents. It should heal with minimal-to-no scarring. The treatment of milia should be performed by a professional! To prevent milia from forming, I would advise a skin regimen which includes a good cleansing agent and Retinol or Retin-A products. If you are using hairspray, try to avoid this getting on the facial skin, as it can occlude the skin pores. I hope this helps.
