Builder Gel, Explained
Quick definition
Thick, self-leveling gel used to add strength or sculpt a subtle extension on natural nails.
Builder gels (BIAB is a famous brand example) create a reinforced overlay that lets brittle nails grow out underneath. Applied in layers, cured under LED, filed to a perfect apex.
It's the go-to for nail-biting recovery and for anyone whose natural nails bend under regular polish.
Is BIAB and builder gel the same?
Yes — almost. BIAB (Builder In A Bottle) is a branded style of builder gel: a thick, self-levelling gel used to strengthen or lightly extend natural nails. “Builder gel” is the category; BIAB is the famous product name people use generically — like saying “Shellac” for any soak-off gel.
