Medicube PDRN Pink Peptide Serum

Sodium DNA is present at roughly 1% — a genuinely dosed level, not a trace amount, matching the front-pack claim. It's the serum's primary functional ingredient, generally known for supporting skin's moisture and repair-supportive environment, working alongside Niacinamide and Adenosine for brightening and wrinkle care.

Each of the five peptides (Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Copper Tripeptide-1, Acetyl Hexapeptide-8) is present at 1ppm per the ingredient list — a trace, formulation-signaling level rather than a treatment-strength dose. The peptide complex is a supporting feature, not the serum's main active.

Yes — it's registered in Korea as a dual-function functional cosmetic, with Niacinamide for brightening and Adenosine for wrinkle improvement. This is a formal regulatory classification backed by disclosed active concentrations, not just a marketing claim.

It contains Fragrance, listed once in the INCI. No specific declared fragrance allergens (e.g. linalool, limonene) appear separately from "Fragrance" on this pack. It also contains Neem (Melia Azadirachta) and Turmeric extracts, which can be mildly sensitizing for reactive skin — patch test if unsure.

The English packaging calls it a "Serum," while the Korean panel names it an "Ampoule" — the same product carries both names across its labeling. Texture-wise, it applies as a lightweight, fast-absorbing liquid typical of both formats; either term describes the same bottle.

Apply an appropriate amount evenly following your skin's texture after cleansing, then pat gently for absorption, per the on-pack directions. It fits into a standard AM/PM routine after toner and before heavier creams or sunscreen.

The formula is fragrance-containing and includes several plant extracts (Neem, Turmeric, Holy Basil), so sensitive or reactive skin should patch test before full-face use. No specific "for sensitive skin" claim appears on the packaging.

Its lead active is Sodium DNA (PDRN) at a genuine 1% dose — the peptide complex present is at trace (1ppm) levels rather than the primary driver. If you're specifically shopping for a high-dose peptide serum, this formula's strength lies in its PDRN and registered brightening/wrinkle actives instead.
