I have rosacea on my cheeks and I'm interested on doing a vbeam treatment with purpuric settings (meaning that I will bruise after the treatment). If the doctor hits all the cheek with the laser but not all bruises (based of pictures I won't have a huge bruise, I will have little ones) will that means that he only shot the laser where the bruises are? Will only the little area that has a bruise be treated or also the sorrounding area will be less red? I don't really understand how bruises work..
