Matcha Dual Serum

Matcha PDRN for Redness-Focused Relief

Introducing the TIRTIR Matcha Dual Serum — a clinically proven, bi-phase serum engineered for intensive redness relief, deep hydration and skin brightening. Combining 2% Jeju Matcha PDRN with 5% Niacinamide (a KFDA-approved brightening active) and powered by the proprietary Dual-Brew Tech™, this serum delivers a rich, cream-like comfort with non-sticky absorption — all in one concentrated, dual-layer formula.

Unlike single-phase serums, the TIRTIR Matcha Dual Serum harnesses a precisely engineered 2:8 cream-to-ampoule bi-phase ratio to deliver two complementary benefits simultaneously: deep calming and redness relief from the Matcha PDRN layer, and visible brightening and barrier improvement from the Niacinamide-rich ampoule layer. Shake to blend, apply, and experience both in one seamless step.

Clinically tested to deliver a 33.48% improvement in redness after 24 hours, a remarkable 319.6% moisture increase on irritated skin, and a 149.9% hydration boost — the Matcha Dual Serum is the most concentrated treatment step in the TIRTIR Matcha Line, designed for those seeking targeted, measurable results for sensitive, redness-prone, dull or dehydrated skin.

Vegan-certified and anti-wrinkle tested, this serum is suitable for all skin types and integrates seamlessly into any K-beauty or clinical skincare routine.

Key Ingredients

2% Jeju Matcha PDRN — Concentrated Redness Calming Active

A 2% concentration of patented Jeju Matcha Polynucleotide (PDRN) — the highest concentration in the TIRTIR Matcha Line — formulated for intensive skin calming and redness relief. Low-molecular-weight PDRN penetrates rapidly to protect the skin from external irritants, reduce sensitivity, and support cellular recovery in reactive or inflamed skin.

5% Niacinamide — KFDA-Approved Brightening & Barrier Ingredient

Niacinamide at the clinically active 5% concentration — approved by the Korean Food and Drug Administration (KFDA) as a brightening ingredient. Reduces the appearance of redness and uneven skin tone, improves skin barrier function, and refines texture for a clearer, more radiant complexion. One of the most well-researched multitasking actives in modern skincare.

Dual-Brew Tech™ — Proprietary Bi-Phase Delivery System

TIRTIR's proprietary bi-phase formulation technology creates an optimal 2:8 cream-to-ampoule ratio, ensuring both the calming cream phase and the brightening ampoule phase are delivered together at their most effective concentrations. The result is a rich, cream-like comfort with non-sticky absorption — combining the nourishment of a moisturiser with the targeted potency of an ampoule serum.

Key Technology & Innovation

Deep Calming Concentration

Instantly soothes skin redness caused by five major categories of external irritation and helps maintain a comfortable, clear skin condition long after application. Clinical data confirms redness relief improves by 23.05% after one use and sustains to 33.48% improvement at 24 hours — demonstrating both immediate and lasting anti-redness efficacy.

Active Dual Synergy

The 2% Jeju Matcha PDRN and 5% Niacinamide work in active synergy: PDRN calms and protects while Niacinamide clarifies and brightens, together addressing the two most common concerns of redness-prone skin — visible redness and uneven, dull skin tone. This dual-active approach makes the serum effective for both reactive and pigmentation-related concerns.

Dual-Brew Tech™

The bi-phase formula with a 2:8 cream-to-ampoule ratio delivers a uniquely rich, comforting texture that absorbs without residue or stickiness. This proprietary technology ensures both phases remain stable, optimally concentrated, and fully bioavailable on application — maximising the benefit of every drop.
