F.O.X Ultrabond is a gentle acid-free primer that ensures strong adhesion to the natural nail. It’s perfect for gel polish, builder gel, acrygel, and bio-gel, providing reliable bonding from the first step. With a delicate formula and minimal methacrylic acid, it’s safe for thin, sensitive, or splitting nails.
It does not alter the pH of the nail plate, won’t cause burning, and doesn’t damage the nail structure. No need for a UV lamp — just apply a thin layer and let it air dry for 30 seconds, then proceed with your base coat.
