Why Everyone Is Talking About the medicube PDRN Pink Peptide Serum

The medicube PDRN Pink Peptide Serum put a salmon-derived ingredient on a lot of bathroom shelves. This edit covers the pink line it anchors, the rest of the medicube routine, and PDRN serums from other brands for comparison.

Every few years one ingredient takes over the skincare conversation, and lately it has been PDRN. So when someone asks me about the medicube PDRN Pink Peptide Serum, I start with the company, because the story explains the ingredient's popularity. APR Corp, the parent of medicube, was founded in 2014 by Kim Byung-hoon, who is still its CEO. It went public on the Korea Exchange in 2024 and, a year later, became South Korea's largest beauty company by market capitalization. The brand itself moved into at-home beauty devices in 2021.

A quick word on the ingredient. PDRN stands for polydeoxyribonucleotide, a DNA-fragment ingredient commonly sourced from salmon or trout, and medicube describes its own as mainly extracted from salmon. The Pink Peptide Serum lists Salmon DNA PDRN, peptide and niacinamide as its key ingredients. I treat it as a nice-feeling serum made for a plumper-looking, glowier-looking finish, not as anything more dramatic than that.

The first grid is the whole pink family. Beyond the serum there is the Collagen Capsule Cream, the Niacinamide Milky Toner, the Peptide Eye Serum and the Peptide Cream. Toner, serum, cream is the order I would use them in, with the eye serum tapped on lightly under the eye at the end.

If you are new to it, start with just the serum for a week. Patch test on your inner arm or behind the ear first, since any new active deserves a cautious introduction.

The rest of the medicube shelf

Once people like one medicube product, they tend to wander down the aisle, so the second grid is for the wanderers. I think of it as the clarifying and brightening half of the brand, which sits neatly beside the pink line.

The Zero Pore Pad is made for a quick swipe over the nose and cheeks, and the Deep Vita C Pad is the vitamin C version. I keep pads like these for mornings when I want a fast step before sunscreen, and I would use only one of them at a time, not both on the same face. They feel like a reset more than a treatment, which is exactly why I like them.

For moisture there are three creams with very different personalities. The Collagen Niacinamide Jelly Cream is the lighter-feeling one of the three. The Deep Vita C Capsule Cream is the one to reach for when you want a glowier-looking finish. The TXA + Niacinamide Capsule Cream is aimed at the look of uneven tone, and it is the one I would introduce slowly.

Then there is the One Day Exosome Shot, which is the ampoule of the group. I would save a shot like that for a night before an event, after a patch test, and layer a plain cream over it.

The idea here is one new step at a time. A shelf full of actives used on the same night is how skin ends up looking tired, not rested.

Other PDRN serums to compare

PDRN is not one brand's property, and comparing a few serums side by side is the fastest way to work out what you actually like. The third grid is that comparison.

innisfree's Retinol Green Tea PDRN serum pairs the ingredient with retinol, and it is marketed for a firmer, smoother look. IOPE's XMD Stem III Clinical Recovery Serum adds an H.A. complex, and it is the most clinical-sounding bottle of the six. Rejuran is the name many people link with PDRN, and its Turnover Ampoule lists c-PDRN 0.5% in the title, so you can read the label and know where you stand.

point of view. makes a snatch it face ampoule serum with pdrn and peptides, which is the playful one of the group. Medik8's Exo-PDRN Prismatic+ is a vegan PDRN serum with a triple exosome complex, a useful option if salmon is a dealbreaker for you. Yepoda's Skinject Effect is an essence with spicules and vegan PDRN, and that is the one I would be most careful with, because spicules can feel prickly on skin.

What I would skip: layering two PDRN serums or pairing one with retinol and strong acids on the same night. More is not more here, and if skin stings, turns red or feels tight, stop and let it settle. Anything persistent is a question for a doctor or dermatologist.

How to try it sensibly

Here is how I would try any of these without overthinking it. Pick one serum, use it on clean skin morning or night, seal it in with a plain moisturizer and sunscreen in the day, and leave it alone for a few weeks.

The small test is how your skin looks at the end of the week, not the end of the first night. If it looks a bit bouncier and feels comfortable, carry on. If it feels sticky, itchy or hot, cut back. I would patch test, add one product at a time, and keep the rest of the routine boring. Labels describe what a serum is made for, and none of them can promise a result, so it helps to keep expectations quiet. A pink bottle is a pleasant start, and steady habits do most of the work.
