What is the difference between gel and BIAB nails?
Build in a Bottle is of a thicker consistency than gel and actually woks to strengthen the nails rather than weaken it. Being a thicker polish also means that it is less likely to chip in between salon sessions. The beauty of BIAB is that is can be used on its own or as a base underneath gel nails to minimise any damage gel polish may cause. The only downside is that BIAB sometimes does not fit into the edges or creases like gel or shellac does. However it does dry harder, meaning it is more durable against chipping.

It is important to note that some people have shown allergic reactions to BIAB nails. There has been multiple at-home users of Build in a Bottle, as well as salon professionals, reporting allergic reactions to it.

Build in a Bottle is suitable for short nails. If you’re prone to brittle nails or have a habit of biting them, this treatment can really help to increase growth. The thickness of BIAB protects the nail and helps to stimulate strength.
