1. Lighting time is not enough, or lamp aging led to the power decline may be the reason for not lighting. Ensure sufficient lighting, timely replacement of the tube or appropriate extension of lighting time can be solved. Note: the lighting time of the bottom and the sealing layer is longer than that of the color glue.
2. The 3D Cat Eye Gel Polish is too thick. If the nail polish glue is applied too thickly at one time, it will not work in the light.
3. 3D Cat Eye Gel Polish itself quality problem, or after the light on the surface of floating glue. If it is the nail itself, then it is recommended to choose a better quality nail, if there is a floating glue, then wipe with a clean cotton on the line.
