A ridge-filling nail primer that doubles as a Biotin and Florium-fortified base coat. One coat instantly levels out unevenness to create a smooth canvas; a second layer further fills in deeper-set lines to conceal the look of bumps. Wear this treatment as a perfected, natural, satin-finish manicure, or use it as a durable base coat that prevents your favorite polish from chipping and peeling. Either way, your nails get immediate and long-term benefits with every use: why mind the gaps when there’s a solution for them?


  • Creates a smooth, even look by filling in bumps and ridges—no buffing required
  • Gently blurs visible nail imperfections with a flawless, matte finish
  • Delivers instant gratification as a perfecting primer while replenishing dry or brittle, weak nails with a blend of botanical oils and extracts
  • Helps prevent breaking, chipping, cracking, peeling, and staining
