What is BIAB and what are the benefits?

We have been hearing the phrase BIAB or builder-in-a-bottle in the nail community, but what is it exactly and why is it different from normal builder gel or acrylic?

First, look at the trend that is BIAB nails themselves. It’s like a no-make up make up look but for your nails as natural nails are getting more popular in some areas than long and extra extensions. BIAB nails come in a multitude of nude and milky neutral shades that provide a super natural and classy look. But of course, any gel polish and trendy nail art can be applied on top of them to amplify the look of your or your clients’ hands.


But why is it different from any other product used for nail enhancements? BIAB is generally more flexible than regular builder gel and acrylic which results in a more natural feel, yet gives a stronger and much more durable manicure than gel polish on its own.

Combined with BIAB, gel polish can last up to 4-6 weeks, and unlike regular gel polish it doesn’t need to be soaked off which makes the next appointment easier,quicker and easier on the skin around the nails. You just need to remove the top layer, a little bit of thickness and any lifting with an e-file, do your infill with the BIAB as you would with regular gel or acrylic, and color and design and you are ready to go!
