KT-939™ Anti-Pigment Serum

Powered by KT939™

The Flagship Serum for Visible Hyperpigmentation.

The Regenvia KT939™ Brightening Serum is our most concentrated pigmentation treatment, formulated around KT939™—a next-generation brightening active developed through biotechnology research to target visible hyperpigmentation at its biological source.

Designed for daily use, this lightweight serum helps improve the appearance of dark spots, post-acne discoloration, uneven skin tone, and dullness while supporting healthier-looking skin over time.

This is more than a brightening serum.

It is the foundation of the Regenvia Brightening Protocol.

Why KT939™

Most brightening products focus on surface discoloration.

KT939™ is designed to work differently.

KT939™ is a next-generation active that targets tyrosinase—the key enzyme responsible for excess melanin production. By helping interrupt excess pigment formation before it becomes visible, KT939™ supports a brighter, more even-looking complexion without relying on hydroquinone or harsh bleaching ingredients.

At Regenvia, we believe breakthrough science should be accessible, transparent, and designed for everyday use.
