Halo Laser Procedure- Day 4 and have white pimples popping up all over? (Photo)

Please follow up with the provider who performed the treatment.  They can effectively analyze the skin to address your concerns.  It may be that you need to be placed on a round of short-term orals for the outbreak. 

This is a common "complication" from people who get fractional resurfacing and needs to be treated with oral antibiotics and topical acne medication. I suggest speaking to your physician but this will improve with the right course of short term treatment. Best, Dr. Emer.
