Is purpura after a pulsed dye laser a guaranteed indication of destroyed vessels?

Purpura usually indicates that vessel has been severely damaged. It is most likely, although never, 100% certain, that this vessel will resolve. 

GENERALLY, purpura is proportional to the outcome. This especially applies to port wine stains and KP (keratosis pilaris) , it also applies to traced blood vessels, especially around your nose area. Purpura or bruising is also the end point for spider vessels, and red age spots. All these condition will respond best to a purpuric setting. Flip side, if you get permanent purpura for say, sundamage on you neck and chest area, this in theory can lead to higher rates of complications. Using the standard default setting on the V BEAM can help. Hope this helpsDr Davin Lim Skin, Cosmetic and laser dermatologistBrisbane. Australia
