TEGO® PEP 4-EVEN

TETRAPEPTIDE-30

A visibly more even complexion, without compromising on gentleness? That’s the promise of Tego® PEP 4-Even, also known as Tetrapeptide-30, a next-generation ingredient that’s increasingly found in skincare products. This biomimetic peptide directly targets pigmentation issues to reduce dark spots, balance melanin production, and restore radiance. It acts at the source of hyperpigmentation while respecting the skin’s sensitivity. The result: an even, luminous complexion, free of irritation or harsh depigmenting effects. All this with optimal tolerance across all skin tones.

What Is Tego® PEP 4-Even — Definition

Tego® PEP 4-Even is a synthetic tetrapeptide. It is a short chain of four amino acids that mimics the natural biological signals that regulate skin pigmentation. This peptide was designed to reduce melanin imbalances without completely blocking its production, making it ideal for skin prone to dark spots, regardless of their cause.

This peptide is produced using biotechnology, which guarantees its reproducibility, stability, and purity. It is incorporated into a water-based formulation that is easy to formulate and bioavailable to the skin.

Tego® PEP 4-Even is part of a new generation of gentle skin-brightening active ingredients that respect the diversity of skin tones while effectively targeting pigmentation irregularities.

Tego® PEP 4-Even — How It Works

Tego® PEP 4-Even works primarily by reducing the expression of the MITF protein, which orchestrates melanin synthesis in melanocytes. By limiting this activity at an early stage, it reduces excessive melanin production without completely blocking the process, thereby preventing any skin destabilization.

This biomimetic mechanism helps prevent and correct the appearance of pigment spots while preserving the skin’s natural complexion. The peptide also acts on inflammatory signaling pathways that can trigger or exacerbate hyperpigmentation.

At the same time, it strengthens the skin barrier and enhances the skin’s protective function. This limits external aggressors responsible for oxidative stress and dark spots caused by sun exposure or pollution.

Finally, its gradual, gentle, and targeted action ensures excellent tolerability, even on the most sensitive skin or skin prone to post-acne or post-UV inflammation.
