PDRN has moved from professional-treatment conversations into Korean cosmetic serums. A topical serum is not the same as an injectable treatment: judge it as a complete skincare formula, including its humectants, texture and tolerability, rather than assuming one headline ingredient guarantees a dramatic result.
By Peony Seoul · Editorial update · Our research method
One PDRN option and two other hydration comparisons
Anua PDRN Hyaluronic Capsule 100 Serum is the PDRN-containing option in this shortlist. WELLAGE Blue Ampoule and Torriden DIVE-IN are included as alternative hydration-serum purchases; we are not presenting them as PDRN serums.
Choose the Anua comparison if you specifically want that formula. If your main goal is an extra hydration layer, compare it with the other two before deciding whether the headline ingredient matters to your purchase. Our hyaluronic acid serum guide explains the 30 ml, 50 ml and 100 ml pack differences and how to compare cost per volume.

| Product | Format | Consider it for | What to check |
|---|---|---|---|
| Anua PDRN Hyaluronic Acid Capsule 100 SerumPDRN-containing option | Serum; finish has not been independently tested | Comparing a PDRN-named hydration serum | “100” is part of the name, not a 100 ml size or an independent performance score. Match the full product listing. |
| WELLAGE Real Hyaluronic Blue Ampoule 100Alternative hydration serum | Ampoule; skin feel has not been independently tested | Comparing a larger hydration-serum bottle | Match the main bottle and any promotional extras. Check the current full formula and directions; size alone says nothing about skin tolerance. |
| Torriden DIVE-IN Low Molecular Hyaluronic Acid SerumAlternative hydration serum | Watery gel serum | Comparing a 50 ml hydration serum | Check your regional ingredient list. Published ingredients do not establish tolerance or pilling with your existing routine. |

Frequently asked
What is PDRN in Korean skincare?
In topical cosmetics, PDRN is used as a formula ingredient in products marketed for hydration and a smoother, more elastic-looking finish.
Is a PDRN serum equivalent to an injectable treatment?
No. A topical cosmetic and a professional injectable treatment have different delivery, regulation and evidence.
Where does PDRN serum go in a routine?
Apply it after toner and before moisturiser, using sunscreen as the final morning step.
Is every PDRN serum the same?
No. Concentrations, ingredient sources, supporting humectants and overall formulas differ, so compare the full product rather than the label alone.
