4 in 1 BIAB Gel PNB is a breakthrough in nail care technology — a primer, base coat, builder gel, and colour all in one. This innovative formula is designed to strengthen the natural nail, promote growth, and minimize breakage without the need for multiple products.
The UV/LED 4 in 1 BIAB Gel PNB, Ivory Glow features a soft ivory shade with a warm milky undertone. The colour delivers a gentle, natural-looking depth that is ideal for classic nude manicures or as a base for nail art.

Perform a dry manicure and prepare the nail plate (preferably with a soft file, not a buffer)
Only apply to healthy, non-damaged nails
Ensure the free edge is at least 1 mm thick
For soft or flexible nails, file the underside of the nail slightly to prevent lifting, then seal with a non-sticky top coat
Remove old product and do not cut the nail length
Prepare and disinfect the nail using Nail Prep PNB
Apply a very thin layer of 4 in 1 BIAB Gel PNB using a rubbing motion, cure for 60 seconds
Reinforce the free edge using the "stress line" technique:
Distribute the gel from stress zone 1 to zone 2, including the growth points
Ensure 1.5 mm thickness around the entire edge
These zones are where nails experience the most pressure during wear
Apply a modelling layer to build structure and fill in sidewalls
Cure for 90–120 seconds using half power mode on your lamp
Remove the sticky layer with Gel Cleanser PNB, file the length if needed
Finish with gel polish and top coat (optional): use Express / Protect / Powder / Shock / Art Top PNB
This BIAB system does not contain harsh adhesion-promoting ingredients. Adhesion is achieved through proper product volume in stress zones, so the stress line technique is essential when working without primer.
You may still use 4 in 1 BIAB Gel PNB with your regular gel overlay techniques if you include a primer and elastic base layer underneath.
