THE SHORT VERSION

The barrier is everything. BioVer-X™ rebuilds it.

Standard resveratrol degrades on contact with skin. BioVer-X™ is a structurally modified polyphenol, patented and exclusive to K&K, that stays stable long enough to reach the dermal layer where barrier proteins are synthesized.

Applied nightly, it reduces the inflammatory signals that accelerate structural breakdown and supports the production of collagen, elastin, and ceramides from the inside.

Strong skin starts one layer down.

THE MECHANISM

What happens at the base layer stays in the barrier.

Most serums deposit active ingredients on the skin surface. BioVer-X™ is engineered to reach the dermal layer, the production floor where collagen, elastin, and ceramides are built.

Once there, it reduces the chronic low-grade inflammation that degrades structural proteins every day. This is not a temporary cosmetic effect. It is a measurable reduction in the signals that drive long-term barrier breakdown.

The result: skin that functions better over time. More resilient. More intact. Less dependent on products to look and feel the way it should.

Most serums stay on the surface. This one goes where skin is built.

THE FOUNDERS

THE FOUNDERS

Two women. One molecule. No shortcuts.

Kristina is a biomedical scientist who spent a decade studying polyphenols in cancer research before realizing the compound she had been working with had a second life in skin barrier repair.

Katie is a skincare specialist who had already built a line of barrier-first formulas from her kitchen. When they met, they realized the ingredient and the philosophy were the same.

They patented BioVer-X™ for cosmetic uses. K&K exists because they believe skin should need less over time, not more.

That is the entire point.

Skin that rebuilds itself.
