How do I know if it is the right temperature?

Applying wax that is not hot enough will cause it to stick and be difficult to remove. On the other hand, applying wax that is too hot can burn your skin and cause discomfort. The correct texture / viscosity is liquid honey. To be safe and certain, test a small bit of wax on your wrist to ensure the temperature is ok before proceeding. Since all microwaves have different heating capacities, heat in small intervals (follow instructions on your wax pot) and stir frequently.

Warm (salon) wax should be heated to 50C while the sugar wax should be heated to 40C.
