Join the BIAB™ revolution — discover the formula that started a movement.

Builder in a Bottle™, BIAB™ and Cover Nude Builders are a range of soak-off gel builders ideal for strengthening natural nails. It also improves and strengthens the quality of natural nails. BIAB™ increases nail flexibility, meaning nails are much less likely to break. BIAB™ is available in various colours, from opaque nudes to sheer shades, as well as warmer and deeper colours.
The unique thing about BIAB™ is that it doesn't need a base coat or primer underneath because it contains a primer in the formula. Because BIAB™ already contains a primer, you need fewer products during treatment and can work faster.

Remember, if it’s not TGB, it’s not BIAB™.
