IPL Device Won’t Flash During Treatment

Potential Causes

• Device is overheating
• Sapphire head is not in full contact with the skin
• Skin is wet or has lotion / gel residue
• Sensor is blocked
• Trigger button issue
• Skin tone is not suitable for IPL use

Troubleshooting Steps

1. Power on first, then place the device on your skin
   Do not place the sapphire head on the skin before powering on.
2. Make sure the sapphire head fully touches the skin
   The device can only flash when the treatment window is in proper contact with the skin.
3. Wait for the indicator light
   Press the flash button only after the indicator light stays on.
4. Keep skin clean and dry
   Do not use the device over water, lotion, cream, oil, or gel.
5. Check the sapphire head
   Make sure it is clean and has no visible cracks or damage.
6. Check the trigger button
   Confirm whether the button can be pressed normally and bounces back.
7. Let the device cool down
   If the device was used for a long time and feels hot, wait until it cools completely before trying again.
