The top coat is cured under UV light in the same way as construction nails, but without the normal construction nail gel. Shellac does not extend the length of your nail and does not need to be maintained in the same way as structural nails. The permanent nail polish can be used to strengthen the natural nail against chipping and tearing. Under normal use, the varnish lasts for about 2-4 weeks! During these weeks, the client does not need to do any treatment on their nails. The long-lasting nail polish gives a really gorgeous shiny and long-lasting nails, because it does not wear off like normal nail polish! Nails can also be embellished with decorations.
