Gel shellac is a hybrid nail polish that combines the long-lasting durability of gels with the ease of application and chip-resistance of traditional polish. Its key ingredients, including resin, pigments, and solvents, create a hard, glossy finish that lasts for weeks without chipping or peeling. Gel shellac is applied in a multi-step process that involves preparing the nails, applying a base coat, multiple colored layers, and a top coat, each cured under a UV lamp to harden the polish.
