I completed about 8 LHR sessions around 9mnths before I purchased another package. Tech supposedly put me on my original temperature for the 2nd new session but I was jumpy. Felt too HOT! I didn’t have burns and felt normal after the session. It’s the DIODE type of laser that’s like an ultrasound w/o zaps. The difference is that I used to go about 1wk before my monthly cycle but now I’m going during ovulation.
