BIAB

"Builder In A Bottle" — a brush-on builder gel that strengthens natural nails while remaining easy to apply.

BIAB stands for Builder In A Bottle. It's a soak-off or buff-off builder gel packaged like a polish, making it beginner-friendly while still adding real structure and strength to natural nails.

BIAB has surged in popularity because it offers the durability of a builder gel overlay with the convenience of a bottle and brush.
