Is it OK to go into a jacuzzi and or hot bath treatment a couple days prior to PicoSure (face)? I wouldn’t go under water.

Hi!  There's no problem going into the Jacuzzi/hot bath a couple days prior to PicoSure.  However, AFTER the laser procedure, you should keep the treated area as cool as possible which means avoiding jacuzzi/hot tub/hot baths/steam rooms/sauna for at least 2 days.  You want to keep your whole body from overheating and sweating.  I also advise avoiding the sun for the first 2-3 days after treatment.  Congratulations on your decision to go ahead with PicoSure treatment.  It is an amazing laser.  

Thanks for your question.  You should be just fine going into a hot tub in the days prior to laser treatment on your face.  You will want to avoid raising your body temperature for a few days after the treatment and definitely don't submerge the treated area or subject it to ANY heat / light source.  Best of luck.
