Is it safe to do external laser lipo 3 times a week like the shop says - it's a Chinese herbal shop.

I am unsure of the strength/type of machine they are using, but generally a recovery period of two to three weeks is advised in between sessions- during which time you should avoid strenuous activities such as cardio exercise. You should also do considerable research in terms of who will be performing the treatment. Are they accredited? Have you checked their before and after photos and testimonials on the treatment? How much practise of Laser Lipo does your practitioner have?

I'm not sure what devices they are using and results can take several weeks after one treatment.  With laser liposuction, I recommend combining with Vanquish and Venus Legacy/Exilis Ultra treatments in order to maximize results. However, you can get great results with VASER, ThermiRF, and ultrasound, if you're a candidate. I recommend getting a formal consultation with a body contouring expert. Best, Dr. Emer

Everything depends on the type of machine that is used. It is difficult to say what the results are going to be without knowing what machine is used. External laser for dissolving fat generally does not work.
