Is It Normal to Have Solid E-matrix Grid Patterns with Raised Blister Like Bumps?

Eventually, at the highest energy levels, the eMatrix moves beyond sublative and can cause epidermal blisering - but this is rare. It will heal. I try to avoid such levels of treatment, if I can. Best,Dr. Karamanoukian

This sounds like swelling along each of the pinpoint areas, which is normal when treating on higher settings. There really isn't a way to "burn" with eMatrix because there's no light or laser component to it, and using the higher settings really does give better results. However, the higher settings can, like you are experiencing, come with a bit of swelling and edema. I would apply hydrocortisone after cool water to the entire face and take an OTC allergy pill. Both of these will help significantly. If you have any other issues, call the office that treated you to be seen.
