Bruising is one of the most common side effects. Tiny bruises at the sites of needle entry may be very inconspicuous and easily covered, but larger or darker bruising that is visible and lasts for days or rarely longer can be rather unsightly. Sometimes (if medically safe) people taking daily aspirin or other blood thinners may temporarily discontinue treatment (always consult your prescribing physician first if you are taking these for medical conditions). Fish oil supplements may be discontinued for a week before treatment and then resumed. If your injector has a pulsed dye laser or certain types of IPL you may be able to return within 24-48 hours for a quick zap. These typically are very safe and speed the resolution of the bruising.
