Our most popular base coat for all the perks of a gel, and none of the fuss or damage. No LED or UV lamp is needed for that extended durability or ultra-plush look. A super smooth base makes painting a dream (not to mention, streak-free), and you get that luxe, cushiony finish for a look that lasts. And though this super base hardens into a strong foundation, it’s breathable and nourishing—both of which are key in supporting healthy nail growth.


  • No UV/LED lamp or special tools needed
  • Creates a cushion between your nail and polish for a plumper, smoother paint job
  • Gives the look of a gel but applies and removes easily like regular polish
  • Boosts mani-pedi longevity by gripping onto polish to prevent chipping and peeling
  • Deeply nourishes to help improve nail health and resilience
