Place the device at a 90-degree angle to your skin, ensuring the laser window is making direct contact with your skin. N.B. do not target the same area twice.
Press the MIDDLE button to use the device on manual mode when in contact with skin. Please note, due to the safety tech, the device will only flash when in contact with your skin.
To speed up the process, activate the automatic mode by holding the MIDDLE button for 2 seconds - you can then glide it along your target areas (perfect for larger surfaces e.g. legs) and it will automatically flash.
