Laser/IPL Hair Removal - How to choose the correct settings
I am often asked 'what are the best settings for my laser for hair removal?' This depends on your laser, obviously, but it also requires a good understanding of the optical and thermal processes.
What is 'fluence'?
This video shows precisely what 'fluence' means. This is important to understand since fluence is a main driver behind all photothermal treatments in the skin,.
