Shellac is a hybrid nail color - it applies like a polish, but cures under UV. You will receive one .25oz new bottle of Shellac UV Top Coat. ShellacTM truly is a hybrid of traditional nail polish and UV gel polish. Unlike soak-off gels it comes in a polish bottle and unlike traditional polish it cures/dries under a UV lamp. Though what I really liked is there is NO BUFFING. There is absolutely no damage to the natural nail in the process. So how does it work? Shellac paints on like polish - base coat, color, top coat - and is cured in a UV light so there is zero dry time. The colors are hypo-allergenic, and "3-Free" - no formaldehyde, toluene or DBP. The formula is thin and flexible like polish, so it not only looks natural, it provides strong natural nail protection with a resilient mirror finish that resists dullness and chipping, even during the most rigorous activities.
