With so many nail polish treatments available, things can get confusing. Shellac is a specific type of gel nail polish, developed by CND. It’s a liquid form of polish cured under a UV lamp for a longer-wearing finish – but, as any shellac or gel nails enthusiast will know, improper removal can leave your nails feeling weak.

Acrylic nails are created using a liquid monomer and powder polymer, which is mixed carefully by your nail professional. They don’t need curing under a lamp but will require an electric file to remove them.

BIAB, on the other hand, is a form of gel polish that has a stronger, more strengthening base. It’s cured under a lamp, with a thicker consistency than gel and is similarly soaked off or removed with an electric file (but it can take a little longer as the formula is quite tough). The main difference? It doesn’t damage your natural nail underneath. Hallelujah.

What are BIAB nails and how are they different from gels or shellac?
