What is Photothermolysis Exactly?


#1

This is what the ad says:

This is where advanced technology comes in. Bio-Hair Touch works on the principle of selective photothermolysis. This means the light energy affects only the unwanted target; in this case, the melanin or pigment in the hair shaft. Surrounding healthy skin is protected and unharmed.

How effective is this?
They told me on the phone is was 80% laser and 20% light treatment.
I have had laser treatments before so I want to know what the difference is…

Bio-Hair Touch is a flashlamp.

Selective photothermolysis is the process which causes lasers and flashlamps to remove hair. It means heating the dark pigment in the hair without heating other stuff in the skin.
