01 — Methodology
How we chose.
The evidence-backed entries use an explicit DNA/polynucleotide-derived INCI name, such as Sodium DNA or Hydrolyzed DNA, or a comparable authoritative disclosure for the exact product. Medicube's retained evidence is a Stylevana retailer listing, while COSRX has an official product-page disclosure. REJURAN's two records remain unresolved/provisional: the retinol SKU has no authoritative exact-SKU evidence, and Turnover has retailer c-PDRN marketing without an exact formulation record. These are comparison entries, not vetted recommendations.
“Rose PDRN” and “vegan PDRN” are marketing labels whose exact material must be checked; they are not automatically fake, and PDRN is not automatically salmon or fish-derived. VT PDRN 100 remains unresolved here because an authoritative INCI, origin, and concentration were not established. COSRX “5 PDRN” means five named PDRN sources, not 5%; its disclosed DNA ingredients have no public concentration. Retailer reviews are context only, not efficacy proof.
02 — The Science
What to look for in a PDRN serum.
01
An explicit DNA/polynucleotide-derived INCI name
Look for a disclosed name such as 'Sodium DNA' or 'Hydrolyzed DNA' in the exact product's ingredient evidence. Origin and concentration can still be unclear, and labels such as Rose or Vegan PDRN require product-specific scrutiny rather than an automatic true/false conclusion.
02
INCI position is context, not a dose assay
Ingredient order can provide formulation context, but it does not prove a meaningful dose or effect. A disclosed concentration is stronger evidence; otherwise say unknown rather than infer zero or therapeutic relevance.
03
Brand context is not product evidence
A brand's injectable, research, or formulation history may add context, but it does not establish the topical product's concentration or efficacy. Keep the product-specific ingredient disclosure separate from brand marketing.
Best documented retailer formula03
Evidence status: Retailer evidence; manufacturer formula not independently verified
Medicube
PDRN Pink Peptide Serum
The exact 30 ml SKU represented here is Medicube PDRN Pink Peptide Serum. The retained Stylevana listing names Sodium DNA, describes a salmon source, and states 1%; those are retailer disclosures rather than independent efficacy evidence.
Its listed supporting formula includes several peptides. Ingredient identity and a stated percentage help distinguish this SKU, but they do not establish absorption or clinical results.
Medicube sells similarly named PDRN products, so confirm the product name, 30 ml size, and destination SKU before buying. Prices and stock were not reverified through the affiliate links.
Pros
- +Exact 30 ml retailer SKU documented in the source ledger
- +Sodium DNA and a stated percentage appear in retained retailer evidence
- +Multiple retailer choices preserved
Watch outs
- −Origin and 1% statement were not confirmed on an authoritative manufacturer formula page
- −Similar Medicube names make variant checking important
Best larger format04
Evidence status: Official product-page evidence
COSRX
5 PDRN Collagen Intense Vitalizing Serum
COSRX's official page lists 50 ml and 100 ml sizes and explains “5 PDRN” through five named sources: salmon, centella asiatica, rice, lactobacillus, and sea grapes.
The name must not be read as 5%. The retained official source did not disclose a PDRN concentration, and the mixture of named sources does not by itself establish dose or efficacy.
The affiliate destinations below point to the 100 ml variant. Confirm size, price, and stock on the retailer page before ordering.
Pros
- +Official product page explains the five-source naming
- +100 ml retailer variant is larger than the 30 ml alternatives
- +Amazon, Stylevana, and YesStyle destinations retained
Watch outs
- −No public PDRN concentration was established
- −The “5 PDRN” name is easy to misread as a percentage
Unresolved exact-SKU evidence05
Evidence status: Unresolved — provisional comparison entry, not a vetted recommendation
REJURAN
Advanced Anti-Aging Retinol + c-PDRN Serum
This is the only current pick whose product name combines retinol with c-PDRN. That makes retinol—not an unverified PDRN dose—the clearest practical distinction.
The retained research did not establish an authoritative exact-variant INCI or c-PDRN concentration. Brand history and injectable products do not prove the composition or performance of this topical serum.
Introduce retinol gradually, use sunscreen, and seek clinical advice for pregnancy or prescription-retinoid questions. Check the linked US retailer for current price and stock.
Pros
- +Distinct retinol-containing option in this comparison
- +Exact Amazon destination preserved
Watch outs
- −Authoritative exact-variant INCI and c-PDRN concentration remain unresolved
- −Retinol may not suit sensitive or retinoid-naive routines
- −Only one retained retailer destination
Provisional retailer evidence06
Evidence status: Unresolved — provisional comparison entry, not a vetted recommendation
REJURAN
Turnover Ampoule
The Turnover Ampoule is the retinol-free REJURAN option in this comparison. Retailer materials position it as a recovery-oriented formula, but positioning is not evidence of clinical or post-procedure performance.
An authoritative exact-variant INCI, c-PDRN origin, and concentration were not retained. Ingredient order should not be converted into a dose estimate.
Use after a procedure only with clinician guidance. Stylevana, Amazon, and YesStyle destinations are retained so readers can compare current terms by storefront.
Pros
- +Retinol-free alternative
- +Three retailer destinations retained
Watch outs
- −Exact c-PDRN identity, origin, and concentration remain unresolved
- −Recovery-oriented marketing is not clinical evidence

The Rose PDRN label and presence of retinal do not resolve the exact PDRN material or concentration.

VT PDRN 100
Neither a plant-derived-mimetic classification nor a functional/high-concentration PDRN classification was substantiated by an authoritative exact-variant INCI, origin, and concentration source.

Product evidence and limitations.
These ordinary source links are separate from the buying links. COSRX is supported by its official product page. Medicube and REJURAN Turnover have retained retailer evidence from Stylevana. The exact formulation for both REJURAN records remains unknown or unresolved; the attempted official pages were not recovered in this audit.
