When do improvements show up? I had microneedling and 2 Vivace treatments in the past 3 months. The last treatment was 2 weeks ago with PRP. I had many red bumps, track marks and scabby areas which have now disappeared. However, I have a few pinpoint holes and developed light brown areas which look like age spots which I did not have before. Family members have noticed them and wondered what happened to my face. I have prepaid for 1 more treatment, but do not want to further damage my skin. Please advise.
