Diode light Sheer (hair removal) on a freshly cut skin, by the razor. What are the side effects?

It is appropriate to have the hair shaved before laser.  This prevents burns on the skin from the laser targeting the hair above the skin instead of below the skin (where the root is - the target).  It would be best if you shaved this at home the day of or day before laser to avoid any cuts.  Even though there may have been a minor cut, you should not experience any difficulties with your laser session.  

This is appropriate treatment because hair has to be at surface with laser treatment.There is slight irritation from razor.
