  intro: "Most people think of base coat as adhesion — a sticky layer that makes polish stick. It is that, but that's the least important thing it does. The more significant function is barrier chemistry. Colour pigment, particularly in dark and heavily saturated shades, stains the nail plate when it sits directly on keratin. The stain isn't cosmetic. It's a sign that the pigment has bonded with the plate surface in a way that requires weeks of new growth to clear. A base coat creates a neutral layer between the pigment and the keratin — and depending on the formulation, it also adds structural support. Protein bases reinforce the keratin layer. Rubber bases flex with the nail to prevent chipping. Peel-off bases sacrifice longevity for clean removal. None of these are interchangeable. Below is the full library: what each base coat type actually does at the surface level, how to pick the right one for your plate, when to layer them, and what happens when you skip the step entirely.",

    body: "Base coat is a barrier layer. It sits between the nail plate and the colour coat, preventing direct contact between pigment and keratin. Without it, pigment — particularly in reds, navy, and black shades — bonds with the plate surface and stains it. Beyond the barrier function, the formulation determines what else happens: protein bases bond with keratin to fill micro-gaps and add surface hardness. Rubber bases create a flexible layer that absorbs impact. The choice between them depends on the plate's current state, not on what colour you're applying over it.",
