Medicube PDRN Pink Peptide Serum
The product that pushed PDRN — polydeoxyribonucleotide, a salmon-derived DNA fragment ingredient — from Korean clinics into home routines. Injectable PDRN has been used in aesthetic medicine for years, and the cosmetic version borrows its reputation wholesale. The serum itself is a light pink fluid with peptides alongside the headline ingredient, pleasant to use and heavily marketed on the strength of the clinic association rather than on topical data.
What it is built around
Who it suits
Normal, combination, dry and mature skin curious about the ingredient and comfortable paying for the novelty. It is a decent light hydrating serum with a comfortable finish and no obvious irritants. It is salmon-derived, so not for vegans or anyone avoiding fish-derived ingredients. If your budget is finite, a retinoid and a sunscreen have far more evidence behind them for the look of ageing.
How to use it
After toner, before moisturiser, morning or evening. A few drops over the face and neck. It layers without pilling and does not conflict with retinoids or acids used at other times. As with anything sold on firmness and elasticity claims, judge it over months rather than weeks, and keep sunscreen as the constant.

What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
What is PDRN or salmon DNA in skincare?
PDRN (polydeoxyribonucleotide), sometimes called salmon DNA, is an ingredient trending in Korean skincare and aesthetic treatments, marketed for a smoother, more revitalized look. In cosmetics its effects are described in appearance terms; stronger claims belong to clinical procedures, not over-the-counter products.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
