A treatment session lasts for 90 seconds, which is auto-programmed into the devices countdown timer. When you press the START button, the 90 second countdown timer will automatically start.
A 90 second treatment session delivers 10.0J of energy (a clinically proven, effective dose).
For maximum efficacy we suggest applying treatment 2-3 times per day, at least 4 hours apart. More frequent use than this is not helpful and is not suggested.
