Introducing New & Improved Primer & Gloss with Exclusive ProStay Technology, for one more full day of polished perfection. Now Up to 11 days of gel-like wear and shine!. How Does Infinite Shine Work? The primer contains a blend of polymers solvents and plasticizers that acts as an anchor to the nail for the rest of the system. The color contains a proprietary oligomer that begins to react once the top coat is applied and the system is exposed to natural light, forming a network of polymer chains that strengthen the color layer. The gloss contains an oligomer and photo initiator that activates the entire system with natural light, starting a reaction in the gloss and color coat, linking the color and gloss layers together, reinforcing the entire application and locking in the shine! Infinite Shine is a state-of-the-art system. When applied as a system, the layers work together to provide long-wear and high-shine.
