Is the choice of cartridge also important when performing the Shurink procedure?

I learned that even if the equipment name is the same, the treatment plan can vary depending on the cartridge used and the depth of application.

I believe it is necessary to check which areas are treated and how the procedure is applied, rather than deciding on a treatment based solely on the name.

When consulting about Shrink, what criteria should be used to determine the cartridge type and application area?
