Medicube PDRN Pink Peptide Serum
Links may contain affiliate codes.
Formulation Summary
A pink-tinted peptide serum featuring Rose PDRN (salmon DNA) and a five-type peptide complex. Niacinamide at an estimated 4.4-5.4% provides brightening support. The formula won the 2024 Glow Pick Award in Korea. It layers hydrolyzed collagen, atelocollagen, and sodium hyaluronate for hydration.
Medicube positions this as a dermatology-inspired anti-aging serum. The five peptide types each target different aging mechanisms: Copper Tripeptide-1 for collagen remodeling, Acetyl Hexapeptide-8 for expression lines, and Palmitoyl peptides for firmness signaling. Sodium DNA provides the PDRN component. Niacinamide appears second in the INCI list, indicating a significant concentration. The formula does contain fragrance, which is a departure from fragrance-free trends in K-beauty.

Key Ingredients
| Ingredient | Concentration | Function |
|---|---|---|
| Sodium DNA (Rose PDRN) | — | Polydeoxyribonucleotide from salmon DNA. Aims to support skin regeneration at the cellular level. Injectable PDRN has clinical support; topical evidence is still building. |
| Niacinamide | 4.4-5.4%third-party estimate | Listed second in INCI. Estimated by third-party analysis at 4.4-5.4%. Provides brightening, barrier support, and oil regulation. |
| Copper Tripeptide-1 | — | Signal peptide that promotes collagen and glycosaminoglycan production. Extensively researched for wound healing and skin remodeling. |
| Acetyl Hexapeptide-8 | — | Targets expression lines by modulating neurotransmitter release at the neuromuscular junction. Effect is mild compared to injectable alternatives. |
The Formulation Explained
Five-peptide approach
The formula uses five distinct peptide types, each with a different mechanism. Copper Tripeptide-1 and the three palmitoyl peptides target different aspects of collagen production and skin firmness. Acetyl Hexapeptide-8 specifically addresses expression lines. This breadth of peptides suggests Medicube is aiming for multi-target anti-aging rather than a single-mechanism approach.
PDRN from clinical to topical
PDRN injections are a mainstream treatment in Korean dermatology clinics. Medicube translates this into a topical product. The key question is penetration. Sodium DNA is a large molecule. The gel vehicle and penetration enhancers like isopropyl myristate may help, but topical efficacy data is limited compared to injectable.
