Medicube PDRN Pink Peptide Serum Review: What’s Really in the Viral Pink Serum

Last updated: October 2026

PDRN is the word of the year in K-beauty. It’s on serums, creams, eye patches, toner pads, even lip masks, and the Medicube PDRN Pink Peptide Serum is the little pink bottle that kicked it all off for a lot of people.

Go looking for a written review though and it’s slim pickings. Mostly Facebook groups and videos. Which is fine for seeing the color, but I wanted to know what’s in the bottle and whether my skin (combination, with type 1 rosacea) would get along with it. So I went through the full ingredient list line by line and read up on what the PDRN research says. The first thing that turned up is that there are two versions of this serum.

What is the Medicube PDRN Pink Peptide Serum?

It’s a lightweight pink serum from Medicube, the same Korean brand behind the Zero Pore Pads. It comes in a 30ml bottle, and the whole idea is bouncier, glowier skin.

The star is PDRN, which on the ingredient list shows up as sodium DNA. Retailer listings for the salmon version quote 10,000 ppm salmon PDRN, which works out at 1%. Medicube’s product copy, as retailers repeat it, also claims visible results in as little as two weeks.

There are two versions, and it matters which one you get

Medicube’s own site sells this serum in two formulas side by side: Salmon DNA PDRN and Rose PDRN, which they label vegan. Same name, same pink bottle – different list.

In the salmon version, sodium DNA is 8th on the list. Its fish extracts (milt extract at 14th, salmon egg extract near the very end) are what stop it being vegan. In the Rose PDRN version, sodium DNA drops all the way down to 30th and the fish extracts are gone, with Rosa damascena extract in their place. Medicube says rose PDRN gives the same benefits as salmon PDRN. That’s their claim, and I’ve no way to check it.

Both versions list isopropyl myristate 4th and both contain fragrance, so the warnings further down apply whichever one you end up with. LOOKFANTASTIC’s page doesn’t print a full ingredient list, so I can’t tell you which version they’re sending out right now. I’d check the box when it arrives.

What’s in it: the good ingredients and what they do

Positions below are from the salmon version’s list on Medicube’s US site.

You also get ubiquinone (that’s CoQ10), hydrolyzed collagen and atelocollagen, plus a little plant blend that includes turmeric and holy basil. All five peptides sit right at the end, so there won’t be a huge amount of any one of them.

Does PDRN in a serum really work?

This is the bit I most wanted an answer to. Most of the research on PDRN is about injections, the skin booster kind you get at a clinic. A 2024 systematic review of those injection studies found promising results for wrinkles and elasticity, but the studies were small and the quality was low to moderate. So even the injection evidence is early days.

Getting PDRN into skin from a bottle is harder – it’s a big molecule with a negative charge, and a 2025 lab paper names exactly those two things as what holds it back in skincare. SkinSort’s notes on sodium DNA say much the same, that applied to skin the effects are likely milder.

There is one encouraging study. In a 2026 split-face trial, a specially sized PDRN eye cream at 0.1% did better than 0.1% retinol on eye wrinkles over 28 days. That’s a different PDRN preparation in a different product, though. Several of the authors also work for the company that makes it, so I wouldn’t read it as proof for this serum.

As for how it’s meant to work, a 2025 review explains that PDRN acts on adenosine A2A receptors, which are linked to calming inflammation and helping skin repair.

So I wouldn’t buy this expecting clinic results from a bottle. What it does have going for it is everything around the PDRN, like niacinamide fairly high up and hyaluronic acid in a hydrating base. That combo can make skin look plumper and glowier on its own. Is the PDRN doing the heavy lifting, or the rest of the formula? Honestly, I don’t think anyone can say for sure yet.

The part I’d want to know if I had sensitive skin or rosacea

It contains fragrance. Fragrance is 20th on the salmon list and 18th on the rose one. That’s not near the top, but it’s there, and fragrance is one of the most common triggers for reactive, red skin like mine. Turmeric root extract is in both versions too, and it’s officially classed as a fragrance ingredient as well as an antioxidant.

Retailer listings call the serum dermatologist-tested and low-irritating. Those are brand claims, so I’d still patch test on your jaw for a few days before it goes all over your cheeks.

Not sure how your skin handles it? Paste the full list into my skin ingredient checker. It flags what’s worth a second look for rosacea, fungal acne, seb derm and pore clogging. And my Korean skincare for rosacea post has the products that helped my redness.

Is the Medicube PDRN Pink Peptide Serum fungal acne safe?

No. And the main reason is right near the top of the list, in both versions.

Isopropyl myristate is 4th. It’s an ester of myristic acid, a C14 fatty acid, and malassezia (the yeast behind fungal acne and seb derm) feeds on fatty acids in the C11 to C24 range. Sorbitan oleate, an ester of a C18 fatty acid, is further down at 24th on the salmon list and 27th on the rose one.

If seb derm or fungal acne is your thing, I’d skip this one. My seb derm face skincare directory has products I’ve already screened.

Watch out for the shortened ingredient lists

Some shops show a short list for this serum that reads “PDRN, peptide complex” instead of the real ingredient names. That isn’t a full ingredient list, and it leaves out the isopropyl myristate and the salmon extracts.

My full list matches Medicube’s own US product page and SkinSort, and both start water, glycerin, dipropylene glycol, isopropyl myristate. If the list you’re looking at is only about 16 ingredients long, it’s the shortened one.

How to use the Medicube PDRN Pink Peptide Serum

LOOKFANTASTIC’s directions say two to three pumps after cleansing and toning, patted in until it’s absorbed, then moisturizer on top.

It plays nicely with most things. If you use a vitamin C or an exfoliant, I’d keep it simple and use them at different times of day rather than piling everything on at once, at least untill you know how your skin feels.

Who I’d recommend it to, and who I wouldn’t

I’d point you at it if your skin is normal to dry and looking a bit tired and flat, and you want a light, hydrating serum with a bit of glow. And if you’re over 40 like me, hydration and bounce are what mature skin starts missing, so a serum that layers easily under a cream makes sense.

I’d skip it if you get fungal acne or seb derm, because of the isopropyl myristate. If you avoid fish ingredients, go for the Rose PDRN version and check the box. Fragrance-sensitive skin should go carefully with either one.

Already a Medicube fan? My Medicube Zero Pore Pad review and Medicube Collagen Night Wrapping Mask review go through those ingredient lists too. For dark spots, my Korean skincare for hyperpigmentation post covers what I’d look at.

FAQs

What does the Medicube PDRN Pink Peptide Serum do?

It’s a hydrating serum aimed at elasticity and glow. It combines sodium DNA (PDRN), five peptides, niacinamide and hyaluronic acid.

Is there more than one version of the Medicube PDRN serum?

Yes. Medicube sells a Salmon DNA PDRN version and a vegan Rose PDRN version. Both contain fragrance and list isopropyl myristate 4th.

Is the PDRN in this serum from salmon?

In the salmon version, yes. Retailers describe it as salmon PDRN, and that list also includes milt extract and salmon egg extract. The Rose PDRN version leaves the fish extracts out.

Is the Medicube PDRN Pink Peptide Serum vegan?

The salmon version isn’t, because it lists milt extract and salmon egg extract. Medicube labels the Rose PDRN version vegan.

Is the Medicube PDRN Pink Peptide Serum fungal acne safe?

No. Isopropyl myristate is 4th on both lists and sorbitan oleate is further down, and both are esters of fatty acids that malassezia can feed on.

Does the Medicube PDRN Pink Peptide Serum have fragrance?

Yes. Fragrance is 20th on the salmon list and 18th on the rose list, so patch test first if your skin is sensitive or rosacea-prone.

Does topical PDRN work as well as PDRN injections?

Probably not. Most PDRN research uses injections, and PDRN’s large size and charge make it hard to get through skin from a cream. One 2026 trial of a specially sized PDRN eye cream looked promising, but it wasn’t this serum.
