Medicube vs. Anua vs. Rejuran PDRN Serum: Which One Makes Sense for You?

Medicube costs $24. Anua costs $30. REJURAN is currently $46.80.

All three sell a PDRN story. They are not selling the same serum.

As checked October 5, 2026, Medicube PDRN Pink Peptide Serum is $24 for 30 mL on Medicube’s U.S. site, Anua PDRN Hyaluronic Acid Capsule 100 Serum is $30 for 30 mL, and REJURAN Turnover Ampoule is $46.80 for 30 mL, reduced from $52 on REJURAN’s U.S. site.

The price difference is easy. The evidence difference takes more work.

Prices can change. More importantly, there is no credible head-to-head clinical trial showing that one of these three finished serums works better than the others.

What Does the PDRN Evidence Actually Show?

Topical PDRN is no longer a research-free category.

A 2026 randomized, double-blind split-face study published in PLOS One evaluated a specific 0.1% PDRN-850K eye cream against a 0.1% retinol eye cream over 28 days. The PDRN formulation produced encouraging results across several measured periocular skin parameters.

That is evidence for that formulation. It is not evidence that every cosmetic containing PDRN is equivalent, and it does not establish that Medicube, Anua or REJURAN is clinically superior to the other two.

The same caution applies to research involving injectable or procedure-based PDRN. Evidence for an injection cannot simply be transferred to a cosmetic serum because they share an acronym.

So the useful shopping question is not, “Which PDRN serum is scientifically the best?”

It is: What else is in the bottle, what does the brand actually substantiate, and what are you paying for?

Medicube PDRN Pink Peptide Serum: The Lowest Price, With One Ingredient-List Problem

At $24 for 30 mL, Medicube is the least expensive of the three.

The Salmon DNA PDRN version combines Sodium DNA with niacinamide and a peptide blend, giving it a broader active-stack approach than a serum built mainly around hydration. Medicube positions the formula around uneven tone, firmness, hydration and glow.

There is one unusually important wrinkle.

Medicube’s current page lists “Fragrances” among ingredients the product is formulated without. On the same page, the published ingredient lists for both the Salmon DNA PDRN and Rose PDRN versions contain “Fragrance.”

Until Medicube resolves that contradiction, this is not a serum we would confidently describe as fragrance-free.

That does not make the entire formula bad. It does mean shoppers who specifically avoid fragrance should check the current packaging and ingredient list rather than relying on the marketing claim alone.

Best fit: someone who wants the lowest entry price and prefers PDRN inside a broader niacinamide-and-peptide formula.

Anua PDRN Hyaluronic Acid Capsule 100 Serum: The Hydration-First Option

Anua makes the clearest case for someone whose main priority is hydration.

Its $30 serum combines salmon-DNA-derived Sodium DNA with multiple forms of hyaluronic acid, hydrolyzed collagen, niacinamide and glutathione. The current ingredient list does not list fragrance.

The brand’s testing claims also line up with that positioning.

Anua reports temporary moisture-plumping improvement of 8.93% after one use and temporary deep-skin hydration improvement of 24.64% after one use. Those are brand-published product claims, not an independent comparison against Medicube or REJURAN.

Anua is not automatically “better” because it publishes hydration numbers. What it gives shoppers is a coherent proposition: PDRN sits inside a formula whose supporting ingredients and published testing both point heavily toward hydration and a dewy finish.

Best fit: someone who wants PDRN as one component of a hydration-focused serum rather than the entire reason for buying the bottle.

REJURAN Turnover Ampoule: The Most PDRN-Centered Brand Proposition

REJURAN is the expensive one here.

As checked October 5, the official U.S. site lists the 30 mL Turnover Ampoule at $46.80, reduced from $52.

Its ingredient list includes Hydrolyzed DNA alongside niacinamide, sodium hyaluronate, licorice root extract, arbutin and adenosine. REJURAN also makes c-PDRN central to the product’s identity rather than treating PDRN as one member of a crowded ingredient ensemble.

That brand positioning is part of what the higher price is buying.

It is not proof that the finished serum works better than Medicube or Anua.

REJURAN’s product page makes multiple appearance-related claims for the Turnover Ampoule, but those should be treated as product-specific brand substantiation rather than evidence of superiority over competing PDRN serums.

REJURAN also sells other c-PDRN ampoule variations, including Dual Effect Ampoule and Triple Radiance Ampoule. They are separate formulas rather than interchangeable names for the Turnover Ampoule.

Best fit: someone who specifically wants the REJURAN cosmetic ecosystem and is comfortable paying more for a formula built around that PDRN-first positioning.

Medicube vs. Anua vs. Rejuran: The Short Answer

Choose Medicube if price matters most and you want PDRN combined with a broader mix of niacinamide and peptides. The unresolved fragrance contradiction is the catch.

Choose Anua if hydration is your clearest priority. Its formula and its published product testing tell the most consistent hydration-first story of the three.

Choose REJURAN if you specifically want a REJURAN c-PDRN cosmetic and the roughly $47 current price does not bother you.

There is no evidence-based reason to crown one universal winner.

PDRN has become skincare’s favorite acronym with a lab coat, but the acronym is not the formula.

Three bottles can all say PDRN while giving you very different reasons to buy them.
