Hardener 635
Key benefits of hardener
- Strengthens the plate and limits breakage and splitting.
- Forms a smoothing protective film, an ideal base before varnish.
- Quick drying with a clear, glossy finish.
- Precise brush application, reliable hold for several days.
Fragile nails that bend or split? Nail hardener 635 creates a thin, even protective layer that supports the nail plate and improves its appearance from the first application. Transparent and discreet, it can be used as a treatment or as a base coat under nail polish to smooth the surface, limit chipping, and reveal a cleaner manicure. Its fluid texture applies smoothly, dries quickly, and leaves a clean, shiny finish—ideal for everyday use. In just a few steps, your nail care becomes simple: the nail plate appears stronger, the edges are better protected, and the nail polish adheres more evenly.
The formula combines film-forming and plasticizing agents that form a flexible network; this adheres to the keratin, visually filling irregularities and helping to reduce breakage. Resins suitable for cosmetic use improve hold, while the controlled fluidity facilitates regular application with a brush. This synergy creates a thin but resistant shield: the surface is smoothed, the shine enhanced and the color of any varnish becomes more uniform. Used alone, the hardener gives a natural “groomed nails” effect; as a base, it optimizes the longevity of the manicure and limits the appearance of chips at the tips of the nails, even on thin nails.
Ergonomic bottle with precise brush; portable size. Transparent finish, base coat compatible.
