Four actives. One eye serum. Every concern addressed. The Medicube PDRN Pink Peptide Eye Serum is a dermatology-grade Korean eye treatment that combines Salmon DNA PDRN, 99% pure Retinol, Niacinamide, and a 10-Peptide Complex in a single lightweight serum — targeting fine lines, dark circles, puffiness, and loss of firmness in the delicate under-eye area with the same clinical ingredient philosophy that defines Medicube's wider PDRN skincare line.
Salmon DNA PDRN is the headline ingredient that gives this serum its name and its core regenerative benefit. PDRN (Polydeoxyribonucleotide) consists of DNA fragments extracted from salmon that are structurally similar to human skin cells, giving them high compatibility with the skin's natural biology. Applied topically, PDRN supports skin regeneration, strengthens the natural barrier, and helps improve uneven skin tone and texture — making the under-eye area, where skin is thinnest and most reactive, appear smoother, more even, and more resilient.
The 99% purity Retinol is the ingredient that works hardest on fine lines and firmness. Retinol at this purity level is the gold standard in topical anti-aging — it accelerates skin cell renewal, stimulates collagen production in the dermis, and thickens the epidermis over time, reducing the depth and visibility of fine lines and crow's feet that develop around the eyes with age. The delicate eye area requires a retinol formulation that balances efficacy with tolerability — the Medicube serum delivers the active at a level appropriate for under-eye skin without the irritation risk of higher-concentration face formulations.
Niacinamide brings brightening and tone-correcting benefits — addressing the darkness and dullness around the eye area that accumulates from poor sleep, sun exposure, and inflammation. Caffeine and Turmeric Root Extract add targeted depuffing and anti-inflammatory support. The 10-Peptide Complex, including Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, and Copper Tripeptide-1, signals collagen production and supports skin structure — the mechanism that makes peptide eye creams effective for firmness improvement over consistent use.
Clinical testing by the Global Institute of Dermatological Sciences found firmness around the eye area improved by 2.87% and moisture around the eye area improved by 22.5% after just one week of use. The hypoallergenic formulation has been tested for safety on sensitive skin.
The non-sticky, lightweight texture absorbs quickly without pilling or greasiness — a practical requirement for an eye serum used morning and evening, often under makeup. Apply a pea-sized amount, pat gently around the eye area, and allow to absorb before applying moisturiser or SPF. Pairs with the full Medicube PDRN line for enhanced results, including the PDRN Booster Gel for use with the Age-R Booster Pro device.
