What it is

BIAB is The GelBottle’s Builder In A Bottle product range.

02

Overlay

Builder gel can add structure over the natural nail without adding length.

03

Extension

Some systems may also be used with forms or tips by trained professionals.

04

Maintenance

Service timing and infill suitability depend on growth and product condition.

05

Design

Colour, French, chrome and small art can be placed over a suitable structured base.

Salon-ready brief

What to ask for

“Ask which exact builder system is being used, how it is cured and how it should be removed.”

Useful note

Uncured acrylate product should not touch skin; allergy concerns need qualified medical advice.
