Q: Has BIAB™ been reformulated?
Yes.
During 2025, we began transitioning some BIAB™ shades to an updated TPO & HEMA-free formulation as part of our longer-term regulatory planning and product development strategy.
Original formula stock remains available in the UK while supplies last and is currently being replenished for the UK market only.

Q: Why were you moving to a TPO & HEMA-free formula?
The removal of TPO was made in response to evolving regulatory requirements.
The removal of HEMA formed part of our broader ingredient review and long-term strategy. As the transition began, we received strong feedback from professionals who rely on the Original BIAB™ performance and consistency. We have listened carefully and acted accordingly to replenish this for the UK market.
Q: Why did you remove HEMA?
When upcoming regulatory changes required us to remove TPO from our formulas, we used that moment to review our system more broadly.
We chose to evolve certain formulas to be HEMA-free. HEMA remains a widely used, compliant and effective ingredient within professional nail systems. Our decision to evolve was driven by a commitment to choice, not a reaction to fear. Only following extensive and successful research and testing was this revised formula released.
Whether you are using our Original or HEMA-Free BIAB™, both are professionally validated, fully compliant, and held to the highest standards of nail health.
We know that some professionals actively prefer HEMA-free systems whilst others prefer to continue working with the HEMA-based formulas they know and trust. In the UK, the Original BIAB™ formula remains part of our range for those who prefer it.
We understand that any formula change can feel unsettling, especially when your reputation and client trust are on the line. Our commitment remains the same: consistent performance, transparency, and long term product development, not reactive shifts.

Q: Is the Original BIAB™ discontinued?
No.
In the UK market, the Original HEMA inclusive BIAB™ remains part of our range and is currently being replenished.
Availability outside of the UK differs by region and is managed by local distributors.
Q: Are both formulas safe?
Yes.
Both the Original and TPO & HEMA-free formulas meet all relevant cosmetic compliance standards and are safe for professional use.
Q: Why wasn’t this communicated clearly at the time?
The transition to the updated formula occurred gradually rather than as a formal relaunch.
We recognise that clearer communication would have been helpful particularly given how widely BIAB™ is relied upon within the professional community.
We have now updated our website to ensure greater clarity and transparency moving forward.
Q: When will Original BIAB™ be back in stock?
Replenishment stock of the Original HEMA inclusive BIAB™ formula is expected in the UK within the coming weeks.
For availability outside of the UK, please contact your local distributor directly.
Q: How do I know which formula I’m purchasing?
Each product page will clearly state whether the shade is:
• Original BIAB™
• BIAB™ TPO & HEMA-Free
If you are uncertain about a recently purchased product, please check our page here.
Q: Are further formula changes planned?
Due to UK regulatory changes coming into effect in January 2027, we are continuing research and development to ensure long term compliance while maintaining professional performance standards.
Any future updates will be clearly communicated.
Q: What about the research you mentioned?
As a company, we are always working behind the scenes on formulation, testing, research and innovation to future-proof what we create.
We are currently undertaking multiple research studies to ensure the performance and standard of our products is never compromised and remains industry leading.
