Nail polish gradually thickens and begins to go badly on the nail plate.
Sometimes he just refuses to dry out when it's so necessary and he has to be washed. People who have many varnishes notice that they quickly deteriorate.
But it can be corrected in a few minutes.
Do not attempt to use a solvent ornail polish remover. Buy in any cosmetic shop a special liquid, its composition is as close as possible to the varnish base and will not spoil your nail cover. Acetone and other liquids can degrade the color, dissolve the sparkles and even spoil your favorite lacquer, and also negatively affect the health of your nails.
Look how much the varnish has dried. If strong, add a little more dilution, and if slightly, then drop 1-2 drops directly into the vial and tighten the cap tightly.
Thoroughly shake the bottles and leave it on 5Minutes, so that the small lumps of lacquer broke up. Then once again shake vigorously and you can start painting your nails. If you notice that the varnish has become too liquid - do not worry, open the lid and let it fade away, the liquid evaporates and you can safely apply the coating to the surface of the nail.
