Vbeam ruined my skin, a month later I have large red spots all over face

I got a Vbeam (intense pulsed dye laser) by a PA at my dermatologist’s office nearly 4 weeks ago for a couple of small broken capillaries on my cheeks & petechiae on my forehead. She did not give me the option of having non-purpura settings (settings she used: 7mm size, 8 joules/cm2, 46 pulses) & she said I had to bruise for it to work. Nearly a month later, I have large red spots that look like chicken pox all over my face. She told me I would be bruised for 10 days but she did not mention that I would have Post-Inflammatory Erythema that may be permanent. She said the only thing I can do to help this is use Arnica cream on my face. If you have pale, fragile skin please ask for one test spot first before getting a treatment with the Vbeam purpura setting & wait 3 weeks to see how your skin responds or find a new provider that will do the non-purpura setting. Unfortunately this is the only dermatologist in my city that does intense pulse dye treatments. I completely regret getting this treatment because my skin looks 100 times worse!
