We always recommend Builder in a Bottle to clients who struggle to grow their nails, whether they bite their nails or have weak nail beds.
We’ve found manicures using BIAB as the base tend to last about a week longer than manicures using our normal gel base coat.
BIAB which stands for Builder In A Bottle, or also known as Builder Gel is fast becoming one of the most popular treatments in the nail industry.
But what is BIAB?
BIAB was created by a British gel brand, and it is designed to harden and nourish the natural nail.
Compared to gel nails, builder gel is essentially a thicker gel including strengthening products that can add length and shape without causing any damage to your natural nails and without compromising the same perfect glossy finish you’d expect from any other nail treatment such as shellac or acrylics.

The strengthening properties can repair and re-shape natural nails. If applied over a longer period, your nails will maintain protection encouraging natural growth.

‘Builder in a Bottle’, also referred to as just ‘Builder’ or ‘BIAB’, is a type of gel developed by makers to nourish and strengthen nails and promote nail growth. It can be used as a replacement to hard gel extensions or acrylic extensions as it’s used on the natural nail and makes them stronger, allowing them to grow past the client’s natural breaking point. It’s also vegan and cruelty-free!
BIAB can be used as a base coat, meaning it goes straight onto the nail bed and bonds to it under UV or LED curing, effectively adding another layer to the nail to strengthen it. We can even use two to three coats on weaker nails, which can make the nail virtually indestructible!
It can be used as a colour as well – all the Builder gels are nude tones – or covered with a gel colour (and nail art!) if the client wants the strength of Builder but not the colour.
Because it’s a soft gel, Builder gel is removed easily with a soak off, whereas acrylic and hard gel need to be filed to be removed. Builder is also ‘breathable’, which is great for those with weaker nails as cuticle oil can penetrate and reach the nail bed.
The Gel Bottle’s website states that it won’t chip or lift – again because it’s a strengthened gel. It increases flexibility on brittle nails which means they’re much less likely to snap
