Medicube PDRN Pink Collagen Glow Jelly Serum

Overview

Medicube markets this on salmon DNA PDRN, and you use it as a targeted treatment step. With an excellent 4.6 out of 5 from over 210 ratings, it is one of the best-reviewed products in its range. Its Amazon listing does not flag strong actives, which is a filter on listing text rather than a safety assessment.

The summary above follows how Medicube markets this product. We also read the published ingredient list line by line, and it tells a different story: what the ingredient order actually says.

How the ratings break down

Amazon's own star distribution for this product, read on 2026-09-30. We show the one-star share too, because an average alone hides it.

5% of these ratings are one or two stars. That is about typical for the Medicube range, where the median is 6%.

We cannot tell you what those reviewers said. Amazon.co.uk now requires an account to open the full review list, so the critical reviews are not readable from a public page. We would rather say that than guess.

What is salmon DNA PDRN?

PDRN (polydeoxyribonucleotide) is a soothing, skin-conditioning ingredient derived from salmon DNA, used to support the barrier and give a plumper, glowier look.

Ingredients, as listed by Medicube

Taken from Medicube's own product page on 2026-08-06. We have not verified it against a physical pack, and formulations change by market and batch. If an ingredient matters to you, check the pack itself. One more caveat for UK readers: Medicube has no separate UK site, so this list comes from its US product page. UK and EU ingredient lists can differ from the US one, so treat this as indicative until you have the pack in front of you.

What the ingredient order actually tells you

• The working formula is a niacinamide serum: water, a second water entry, glycerin, then niacinamide fourth of 42. That is the part of the bottle doing the most.
• The salmon DNA sits 13th, which is well above where this range usually places it. If you want Medicube’s PDRN story, the order here supports it better than the masks and mists do.
• The collagen in the name is not on the list. There is no collagen entry among the 42. Pink Collagen is the range name here, not a description of this bottle.
• Seven hyaluronic entries cluster from 27th to 34th, a vitamin C derivative at 27th, and a single peptide at 37th. Those are the texture and marketing layers rather than the payload.
• No fragrance entry appears, which suits a leave-on serum you apply daily.

Our read

One of the better-ordered PDRN products in the range, as long as you read the name correctly: niacinamide fourth, salmon DNA 13th, no fragrance, and no collagen at all. Read it as a niacinamide serum with a genuine supporting dose of the ingredient the range is built on, and it is a sound buy. Read it as a collagen serum and you are buying a word.

Who should skip this

• You are buying it for the collagen. There is no collagen entry on this list.
• You already run a niacinamide serum. This duplicates that slot rather than adding to it.
• You want the peptides to matter. There is one, at 37th of 42.
• You want a rich, occlusive finish. This is a lightweight water-jelly by design.

A note on how we read that list. Ingredient lists run in descending order of concentration, but only for ingredients above 1%. Below that, the order is up to the manufacturer, so a low position tells you something is present at a low level, not exactly how much. We do not guess at percentages. FDA labeling guide.
