Why is nail polish sticky after curing?

In fact, this is normal! Even if you keep shining the light, it will not dry. After the gel nail polish is cured, there will be a layer of "residual glue layer" on the surface, which will feel a little sticky. This is because the topcoat has not been applied yet. The topcoat is the last step. It can seal the glue surface, help you remove the stickiness, and make the nails brighter and longer-lasting. So remember to apply a layer of topcoat glue after the color glue is cured, and then shine the light to cure it, so that the nail surface will be dry and not sticky, and the effect will be more perfect!
