Tattoo removal, E-Raze/LI-FT/Saline

[Amandatron]

Hi, I'm qualified and insured in E-Raze tattoo removal but I'm looking to move on to either LI-FT or saline solution. - Does anyone know if I would need to complete a course in LI-FT or Saline to be able to perform this treatment as the procedure looks the same? TIA!!
