White Bumps a Day After Being Treated with V-beam Laser and Levulan PDT?

Hello, so I just had a treatment with v-beam and levulan followed by PDT yesterday. My face was cleaned with accetone and then levulan was applied. I sat for about 2 hours in a dark room, then my dermatologist used the v-beam laser on me, and then I was put under a light for photodynamic therapy for 20 mins. It has now been over 24 hours since my treatment. My face is bright red and tight-feeling and I've developed little white bumps all over my face. I was wondering if these bumps are normal?
