Medicube PDRN Pink Peptide Serum 30ml
It's Vitamin B12.
What It Is
Medicube PDRN Pink Peptide Serum is a firming, hydrating treatment built around Polydeoxyribonucleotide (PDRN) sourced from salmon, paired with a five-type peptide complex designed to support skin's elasticity and bounce. The formula's signature pink tone comes from Cyanocobalamin (Vitamin B12), not artificial dye, and it layers Niacinamide for tone-evening, multiple forms of Hyaluronic Acid for hydration, and Coenzyme Q10 for additional antioxidant support. Reviewers consistently describe the texture as lightweight and fast-absorbing despite its rich ingredient list, with a noticeable but not overwhelming rose scent.
Why This PDRN Serum Stands Out
- >
- and is one of the most talked-about "regenerative" ingredients in current K-beauty, credited in early research with supporting cell repair and collagen-related activity, particularly in wound-healing contexts. >
- including Copper Tripeptide-1 and Acetyl Hexapeptide-8, rather than relying on PDRN as a single active — this multi-peptide approach is a key differentiator from single-ingredient PDRN serums. >
- It comes from Vitamin B12 (Cyanocobalamin), an ingredient associated with skin-brightening support, rather than an added colorant. >
- as one of the two most-searched PDRN serums in the category — Medicube differentiates through its broader peptide-plus-PDRN stack rather than PDRN concentration alone.

Key Ingredients
Polydeoxyribonucleotide derived from salmon, one of the most discussed regenerative ingredients in current Korean skincare. Early research associates PDRN with supporting skin repair processes and collagen-related activity, particularly in the context of wound healing.
Includes Copper Tripeptide-1, Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, and Palmitoyl Tetrapeptide-7 — a layered blend of peptides that work through different mechanisms to support skin's firmness and elasticity.
A well-studied form of Vitamin B3 included to support a more even-looking skin tone and complement the formula's overall brightening effect.
Responsible for the serum's signature pink color, this form of Vitamin B12 is included as a functional ingredient rather than a cosmetic additive, contributing to the formula's brightening profile.
Supports moisture retention alongside the peptide and PDRN actives, contributing to the plump, bouncy texture reviewers commonly describe after use.
Supporting Ingredients
An antioxidant compound included to help support skin against everyday environmental stress, adding to the formula's overall collagen-supportive positioning.
A botanical extract included for its calming properties, helping balance the formula's active ingredients with a soothing effect on the skin.
Additional marine-derived ingredients rounding out the formula's regenerative-support positioning, working alongside the PDRN and peptide complex.
Who It's For
- >Uneven skin tone and dullness >Early signs of aging, fine lines >Dry or dehydrated skin >Skin needing extra firmness and bounce >Fans of PDRN and peptide skincare trends >Vegan skincare users >Those comfortable with fragranced products >All skin types, though richer for dry/normal skin
How To Use
- >
- Many users report a single bottle lasting several months with consistent daily use. >
- Since this formula contains added Fragrance, those with reactive or fragrance-sensitive skin should test on the inner arm first. >
- The serum hydrates well on its own but pairs best with an occlusive moisturizer during dry seasons. >
- Reviewers note visible texture and tone improvements typically build over one to several weeks of consistent use. >
- to help preserve ingredient stability between uses.
