does this sound like a bad reaction??

Hi over a couple of weeks ago, I had laser treatment on my back. Prior to this I have had six treatments done on the back without any reaction, however this time, i now seem to have developed lots of what looks like acne on the back, and I can still feel the stubbly feeling of hair on the back, i.e i do not think it has shed. I have never experienced this before, and am using the same settings as last time. Does this sound like i am experiencing a bad reaction to the laser, and if so is there anything I can use?

Thanks,

Do you have acne, ingrowns, or both?
