I just had my first IPL treatment. I bought a three treatment package for full face. My question is: the doctor spent about 7 minutes on my face, with maybe 12-14 "snaps" of light. Is this all that is needed, and is this considered doing the full face? Does the light radiate out from the area pulsed to the surrounding area? I don't see any effect at all, not even redness. Am I being ripped off do you think?????
