Getting to Know TRIA Laser
There are three separate components of the TRIA laser hair removal system. The unit itself, the charger, and the skin sensor. The skin sensor is used to against your skin and “authorizes” the main unit to begin laser treatments.
Once the TRIA is fully charged, you hold the skin sensor up against your skin where you want to begin treatments. By pushing on the button at the top of the sensor while it is placed on your skin, you’ll get a green light if that location has been approved. Then you hold the sensor over the turned on unit — it beeps its “authorization” and you’re ready to go.
