BIAB, which stands for ‘Builder In A Bottle,’ is a nail system that combines the benefits of gel polish and builder gel. It is a all round product suitable for both natural nail treatment and nail extension. BIAB nails are often praised for their durability and strength, making it a popular choice for both nail technicians and clients looking for long-lasting, perfect-looking nails.

BIAB nails have excellent durability and can last up to 4 weeks without chipping or fading. It looks natural as a semi permanent but has the durability and strength of a builder gel. Making it an ideal choice for those striving for a perfect look amid busy schedules.

The main difference between BIAB, builder gel, semi permanent and acrylic is in their applications and properties:

Semi permanent: is a gel product used to strengthen and colour natural nails. It offers a beautiful glossy finish and lasts longer than traditional nail polish, it is also easy to apply like nail polish. You can usually choose from a Peel base or Soak base here.
Builder Gel: is mainly used for lengthening nails and creating a solid base. It is thicker than BIAB and requires several coats. Builder Gel is usually less flexible to work with. Before this builder gel, you also need a builder gel.
Acrylics: are made by mixing a liquid and powder, which causes a chemical reaction that hardens the nail. Acrylic is very strong, but it can damage natural nails if misapplied or removed. Moreover, it often has an unpleasant odour.

Within the BIAB B System, there are 3 types of gels. Who needs which gel? That depends on your client, their daily habits and the length of the nails. Remember: the client chooses the colour and you choose which type of gel is needed. Does your client want a colour look? Then choose BFLEX or BSTRONG Clear and finish the look with BCOLOUR.

SAME SUCCESSFUL FORMULA & TPO FREE

The natural nail look with short, clean nails and an elegant nude finish remains incredibly popular.

Did you know that there are already 27 and more BFLEX shades? Combining BSTRONG with BFLEX creates endless possibilities within the nudes shades!

You build the gel nail with BSTRONG and finish with a layer of BFLEX as a tinted gloss layer. If your client wants an extension, you extend the nails first with BSTRONG and then build the nails with BSTRONG as well. You are then done because BSTRONG also shines like a gloss. But if you still want to offer a different shade, then finish by applying a layer of BFLEX of your choice as a tinted gloss.

Tips

If you want to give a BFLEX colour more transparency, first build with BSTRONG CLEAR.
If you want to lighten the BFLEX colour, build with BSTRONG PURE first.
And if you want to create an ombre, build with one of the BSTRONG shades and combine it with a contrasting or complementary BFLEX shade.
Does your client always go for the same nude shade? You can skip the BSTRONG Clear base layer and go straight to applying your slip and drop layer – one step less and an ultra-thin nail.
All nude shades of BSTRONG are suitable for building, extending, or a French look.
BSTRONG Clear remains essential as a base layer for clients who love to switch nudes and as a protective gloss over BCOLOUR.
