BIAB

Builder In A Bottle

​

 

‘Builder in a Bottle’, also referred to as just ‘Builder’ or ‘BIAB’, is a type of gel developed by makers The Gel Bottle 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!
