I had a Clear and Brilliant Treatment today, do I need to avoid exercise where I will be hot and sweaty for a few days?

That is a very good question!  We recommend that you wait until the next morning to exercise as the exercise may make the facial swelling worse.  We recommend that you use a thick cream the first evening in order to protect the skin and promote healing.  In some patients we recommend using PRP after the PRP to speed recovery, but his is mostly for more invasive lasers like ActiveFx or Fraxel.  The best answer for this question is the treating physician because each physician as their own defined regimen.  

For lasers like clear and brilliant we have patients wait 24 hours before exercising.  I suggest you talk to your physician tho.  For facial rejuvenation I would consider a combination approach:
1) skin care with products and PRP/microneedling

2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel, Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production
5) thermage/ultherapy for yearly skin tighteningBest, Dr. Emer.
