PDRN Brightening Duo — Medicube PDRN Pink Peptide Serum + Anua Niacinamide 10% TXA 4% Serum

Two of the most powerful brightening serums in K-beauty — in one bundle.

Dark spots, uneven skin tone, dullness — this duo attacks all three simultaneously. The Medicube PDRN Pink Peptide Serum works at the cellular level to regenerate and restore. The Anua Niacinamide TXA Serum brightens, fades hyperpigmentation, and evens your complexion on the surface. Together they create a brightening system that delivers visible results faster than either serum alone.

Serum 1 — Medicube PDRN Pink Peptide Serum (30ml)

PDRN (Polydeoxyribonucleotide) is a next-generation regenerative ingredient — the same active used in clinical skin treatments — now available in a daily serum. It accelerates cellular regeneration, repairs damaged skin, reduces the appearance of pores and fine lines, and restores radiance from within. The signature pink formula combines PDRN with peptides and niacinamide for a triple-action approach to skin renewal. Lightweight and fast-absorbing, it layers beautifully under any moisturizer.

Key ingredients: PDRN · Peptide Complex · Niacinamide · Adenosine
Best for: Dullness · Fine lines · Uneven texture · Skin regeneration
Free from: Parabens · Artificial fragrance

Serum 2 — Anua Niacinamide 10% + TXA 4% Brightening Serum (30ml)

The viral brightening serum that took TikTok by storm — and for good reason. This triple-action formula combines 10% Niacinamide, 4% Tranexamic Acid, and 2% Arbutin to visibly fade dark spots, post-acne marks, and hyperpigmentation while improving overall skin tone. Lightweight, water-based, and fragrance-free — it works on all skin types including the most sensitive.

Key ingredients: 10% Niacinamide · 4% Tranexamic Acid (TXA) · 2% Arbutin
Best for: Dark spots · Hyperpigmentation · Post-acne marks · Uneven tone
Free from: Artificial fragrance · Parabens · Silicones
