  deck: "UV and LED cure, real two-week wear, and the lift-versus-chip distinction that changes how you think about longevity.",
  intro: "Gel polish is not just long-lasting lacquer. The chemistry is fundamentally different: photo-initiators in the formula react under UV or LED light, triggering a polymerisation cascade that cross-links the film into a hard, flexible coating bonded to the nail surface. That's why it doesn't chip the way regular polish does — it lifts. The failure mode is at the seal, not the surface. Understanding this distinction changes everything about application, maintenance, and removal. It's also why gel polish removed by peeling does real damage: you're not stripping a surface coating, you're mechanically pulling a layer that's chemically bonded to the top of your nail plate.",

    h: "What gel polish actually is",
    body: "Gel polish is a urethane acrylate or methacrylate oligomer formulated with photo-initiators — compounds that generate free radicals when exposed to specific wavelengths of UV or LED light. Those free radicals trigger polymerisation: the liquid monomer chains link together and harden into a semi-rigid film in 30 to 60 seconds under an LED lamp, or 2 minutes under a traditional UV lamp. The result is a coating that is bonded to the nail surface rather than simply sitting on it. Wear of 10 to 14 days without chipping is achievable because the film is flexible enough to move with the nail's natural flex without fracturing at stress points.",
