KT-939™ Brightening Duo

Powered by KT939™

A New Generation of Pigmentation Science.

The Regenvia Brightening Duo is powered by KT939™, a next-generation brightening active developed through biotechnology research to target visible hyperpigmentation at its biological source.

Unlike traditional brightening products that focus only on surface discoloration, the Regenvia Brightening Protocol combines KT939™ with niacinamide, barrier-supporting ingredients, and advanced hydration to help improve the appearance of dark spots, post-acne marks, uneven skin tone, and overall skin clarity.

No hydroquinone. No harsh bleaching agents. Just precision skincare inspired by regenerative science.

Why KT939™

At the heart of every Regenvia Brightening Protocol is KT939™—a next-generation active designed to inhibit tyrosinase, the key enzyme responsible for excess melanin production.

By targeting visible pigmentation before it reaches the skin's surface, KT939™ helps support a brighter, more even-looking complexion while remaining suitable for consistent daily use.

KT939™ represents a new generation of pigmentation science—bringing biotechnology innovation into everyday skincare.

Key Benefits

Targets Visible Hyperpigmentation

Promotes Brighter, More Even-Looking Skin

Supports healthier-looking skin with improved clarity, luminosity, and overall tone through a daily brightening protocol.

Supports a Healthy Skin Barrier

Niacinamide and complementary barrier-supporting ingredients help strengthen the skin's natural defenses while reducing visible redness and environmental stress.

The Regenvia Brightening Protocol

Designed to:

Step Two

KT939™ Brightening Lotion

A deeply hydrating moisturizer that reinforces the skin barrier while helping maintain a brighter, healthier-looking complexion.

How to Use

Morning and evening:
