Is It Normal to Have A Rash After Laser Resurfacing?

Having an itchy rash after laser resurfacing can be a reaction to a numbing cream that was applied before the treatment or creams that you are using after. Painful rashes after resurfacing could be a sign of a herpes cold sore outbreak, and depending on which laser was used, it is very important that you tell your doctor immediately as it can cause scarring. If it is a bacterial infection it can get worse and scar and cause serious medical problems so call your doctor now and if you can't reach them, go to an emergency department to see if you need treatment for herpes and/or a bacterial or yeast infection.  If it is an allergic contact dermatitis to the creams then you will need different treatment for that. After your urgent care, be sure your doctor knows about the development if you didn't see them and get follow-up care from them.

Contact your doctor immediately. It is likely that you have an infection (yeast, bacterial or less likely viral).  It is also possible, but less likely that you are having an allergic reaction to something.  All of these need urgent treatment.
