SNS is a nail dipping system and stands for Signature Nail Systems. It’s a long-lasting alternative to other nail enhancements such as Shellac. The nails are prepared in the usual way, then dehydrated and cleaned, then a coat of resin is applied, then dipped quickly into the powder, then repeated several times to create the shape desired. This is often preferable because it is seen as the healthier nail enhancement option, but this is simply because it’s such a quick process. The benefit of SNS is it generally is very quick and requires very little filing and therefore it is healthier for the natural nail with reduced friction.
It is because it is fast, easy and relatively fumeless as well as more hard wearing than gel polish creating a stronger enhancement, plus colour that doesn’t chip.
SNS is removed by soaking in acetone. This breaks down the glue/powder mix and it comes away pretty quickly.
