The Gelish PRO – Foundation Flex (Clear) is a professional soak-off base gel designed to deliver superior adhesion while maintaining flexibility and comfort. Its unique formula helps reinforce the natural nail, reducing breakage and creating the perfect foundation for gel polish or enhancements.
Applied as the first step in the Gelish system, Foundation Flex ensures smoother application, longer-lasting colour, and a protective barrier for the natural nail. The clear formula makes it ideal for layering under any shade, providing versatility for both professional salons and at-home users.
Packaged in a 15 mL (0.5 fl. oz.) bottle, it’s easy to apply, LED/UV curable, and removes quickly with a soak-off process—leaving nails healthy and damage-free.
