About us

Behind the dazzling world of nail art lies a story few have ever heard.
Since 1996, in Changyi, China, a biochemical company named Longchang began a deep and quiet exploration of “beauty.” For nearly three decades, their laboratories held no vibrant colors—only a relentless pursuit of perfection at the molecular level. They supplied safe, stable core ingredients to leading global brands, protecting the beauty on fingertips worldwide while never stepping into the spotlight.

In 2024, a new dream was born—CHROMA GROUP LIMITED.
We asked ourselves: Why not transform nearly thirty years of biotech expertise into exceptional products that every beauty lover can use with confidence?

And so, CHROMÉCLAIR UV Gel Polish came to life.

We believe true luxury is beauty without compromise. While much of the industry still relies on potentially sensitizing ingredients like TPO and HEMA, our R&D team drew inspiration from thousands of formulations developed at Longchang and set out to spark a “clean-ingredient revolution.”
It was a challenging climb—but we have always believed that safety is the foundation of beauty.

Today, we are proud to announce that CHROMÉCLAIR’s new formula achieves our “Double-Free” promise—TPO-Free and HEMA-Free.
This is more than removing ingredients; it’s a complete redefinition of what healthy nail beauty can be.
It means lower sensitization risks.
It means salon-level color performance and shine delivered with unmatched gentleness and peace of mind.

CHROMÉCLAIR means “clear, Lightning Coloring, bright color.”
This light is illuminated by 29 years of scientific expertise from Longchang—and by our commitment to letting every user shine with confidence.

We are not just a new brand. We are the inheritors and innovators of decades-old wisdom.
We invite you to experience this Since 1996, Peace of Mind.

“You’re not choosing just a bottle of gel polish — you’re choosing a new standard for healthy nails. While others are still using formulas from decades ago, we’ve already moved on to the next generation.”

We come from the formulation side — not just reselling gel polish. We’ve worked with UV curing systems for years, so we know what actually matters inside the bottle.

This formula wasn’t adapted later. It was developed from day one to meet strict European safety standards. Safety wasn’t an afterthought for us — it was the starting point.
