8 Korean PDRN Serums Compared: Price per ml, Formula and Best Value
The direct answer
For the lowest current cost per milliliter, the 100 ml COSRX serum is the clear value leader at about $0.23 per ml. Beauty of Joseon is the least expensive 30 ml bottle at about $0.67 per ml, while MEDIHEAL offers a useful middle ground with 40 ml, a pump, squalane and a current cost of about $0.59 per ml. Those numbers do not make one serum best for every routine. Anua is focused on multi-form hyaluronic acid and a dewy capsule-serum experience, Abib combines a brand-disclosed 4% PDRN claim with an airless pump, numbuzin uses a dense jelly formula with collagen water, peptides, a cooling agent and hydrolyzed sponge, Medicube combines PDRN, peptides and a richer pink serum base, and IOPE is the most expensive but has the clearest caffeine-specific positioning.
The practical choice is profile-dependent. Buy COSRX when volume and everyday hydration matter most. Choose Beauty of Joseon for a compact, silky, lower-cost 30 ml option. Consider MEDIHEAL for a more emollient finish and pump format. Choose Abib when concentration disclosure and airless packaging justify a higher price. Choose IOPE only when its plant-derived Bio-PDRN and 20,000 ppm caffeine positioning matches the exact job you want the serum to perform.
Quick verdicts by buyer profile
Best value by volume
COSRX 5PDRN Collagen Intense Vitalizing Serum 100 ml. Its bottle is more than three times the size of most options here, and its current price is close to several 30 ml competitors. It is the strongest economic choice for a person who will use a hydrating serum consistently and finish a large bottle.
Best lower-cost 30 ml bottle
Beauty of Joseon Pore Firming Serum. It combines a silky, layerable texture with squalane, ceramide NP, beta-glucan and a peptide, while remaining the least expensive 30 ml product in this comparison.
Best for a richer, emollient finish
MEDIHEAL PDRN Lifting Serum with Squalane. The 40 ml pump formula contains squalane, cetyl ethylhexanoate and caprylic/capric triglyceride. It is better aligned with dry-feeling skin than a buyer seeking the lightest possible watery layer.
Best for declared concentration and pump control
Abib PDRN Glow Serum 4.0 Pump. Abib discloses 4% PDRN and uses an airless pump. Its price per ml is high, so the case for buying it rests on formula transparency and packaging rather than budget.
Best for a caffeine-specific formula
IOPE Expert PDRN Caffeine Shot Serum. IOPE discloses 38% of its proprietary plant-derived Bio-PDRN complex and 20,000 ppm caffeine. It is also the highest-cost product here, so it makes sense only when that differentiated formula is relevant.
Methodology and price date
Prices, stock status, variants and net contents were checked on ProtoClinical on August 3, 2026, in USD. Price per ml equals current product price divided by confirmed net volume. Cost-per-use estimates use three transparent scenarios: 0.15 ml, 0.25 ml and 0.35 ml per application. These are comparison scenarios, not brand dosing measurements. Pump output, dropper fill, viscosity and user technique can materially change actual use.
The decision matrix weights profile fit at 20%, formula coherence at 20%, cost per ml and use at 20%, tolerability at 15%, texture at 10%, routine compatibility at 10%, and packaging and transparency at 5%. Scores are navigation tools, not efficacy grades. A formula can score well for broad daily use and still be the wrong choice for a person who avoids fragrance, dislikes cooling sensations, wants a pump or needs a specific caffeine formula.
Main comparison table
| Product | Price | Size | Price/ml | 30 uses at 0.25 ml | Practical strength | Main limitation |
|---|---|---|---|---|---|---|
| Beauty of Joseon Pore Firming Serum | $19.95 | 30 ml | $0.67 | $4.99 | Silky 30 ml value; squalane, ceramide and peptide | PDRN concentration not disclosed |
| MEDIHEAL PDRN Lifting Serum | $23.71 | 40 ml | $0.59 | $4.45 | Emollient pump formula with squalane | Rose and cypress aromatic oils in INCI |

| numbuzin No.2 Rose PDRN Collagen 2X | $27.74 | 30 ml | $0.92 | $6.94 | Jelly formula with collagen water and many peptides | Cooling agent and hydrolyzed sponge add sensory complexity |
| Medicube PDRN Pink Peptide Serum | $25.96 | 30 ml | $0.87 | $6.49 | Peptide-rich, dewy pink serum | Fragrance is listed; official page shows multiple formula versions |
| COSRX 5PDRN Collagen Intense Vitalizing Serum | $23.17 | 100 ml | $0.23 | $1.74 | Large pump bottle; broad hydration and tone-support formula | Large size only saves money if it is used consistently |
| Abib PDRN Glow Serum 4.0 Pump | $30.10 | 30 ml | $1.00 | $7.53 | 4% brand-disclosed PDRN and airless pump | High cost per ml; inherent marine-ingredient odor is disclosed |
| IOPE PDRN Caffeine Shot Serum | $49.33 | 30 ml | $1.64 | $12.33 | Bio-PDRN complex plus 20,000 ppm caffeine | Highest price; specialized formula is unnecessary for many routines |
All eight products were active and available on ProtoClinical when checked. Stock can change faster than editorial content, so the product pages remain the source of truth at checkout.
What value means in this comparison
Value is not the lowest sticker price. It is the relationship between usable volume, formula fit, dispensing control, sensory tolerance and the chance that the bottle will actually be finished. A 100 ml serum is poor value when its texture conflicts with the rest of the routine or when a broad formula duplicates several products already owned. A more expensive 30 ml serum can be rational when its pump, disclosed concentration or differentiated ingredient system solves a real purchasing constraint.
Bottle size changes the economics sharply. At the middle 0.25 ml scenario, a 30 ml bottle provides about 120 applications, a 40 ml bottle about 160, and a 100 ml bottle about 400. Actual duration also depends on dispensing and application area.
Eight products, analyzed on the same criteria
1. Beauty of Joseon Pore Firming Serum Red Bean PDRN + Peptide 30 ml
Beauty of Joseon is the strongest compact-budget option. The official formula lists red-bean-derived Sodium DNA, niacinamide, glycerin, Glycereth-26, squalane, hydrogenated lecithin, ceramide NP, beta-glucan and Dipeptide Diaminobutyroyl Benzylamide Diacetate. It is a lightweight humectant-emollient formula with a barrier-lipid component and one named peptide. The brand describes the finish as silky and suitable for layering.
Best fit: someone who wants a 30 ml dropper serum between toner and moisturizer. Limitation: the brand does not disclose a PDRN percentage, and its pore results are product-specific brand studies, not a reason to expect permanent pore-size change. View the Beauty of Joseon serum.
2. MEDIHEAL PDRN Lifting Serum with Squalane 40 ml
MEDIHEAL pairs Sodium DNA with a clearly emollient base. Cetyl ethylhexanoate, caprylic/capric triglyceride, squalane and cetearyl alcohol sit alongside glycerin, sodium hyaluronate, betaine, panthenol, beta-glucan, ceramide NP and Oligopeptide-1. The pump is practical for repeatable dosing, and the brand directs users to apply one or two pumps morning and evening.
Best fit: dry-feeling or normal skin that benefits from more slip and emollience. Limitation: Rosa damascena flower water, rose flower oil and Chamaecyparis obtusa oil are present. The formula should not be described as fragrance-free simply because parfum is absent. View the MEDIHEAL serum.
3. Anua PDRN Hyaluronic Acid Capsule 100 Serum 30 ml
Anua is the hydration-led choice. The official INCI starts with water, butylene glycol, propanediol and glycerin, then adds hydrolyzed hyaluronic acid, niacinamide, hydrolyzed collagen, additional hyaluronic-acid forms, glutathione and Sodium DNA. The brand positions it as a lightweight capsule serum with a dewy, moisture-plumped finish. No parfum or essential oil appears in the official ingredient list.
Best fit: a buyer who wants a fragrance-free, glow-oriented serum and prefers humectants over a richer oil phase. Limitation: the current price is over $1 per ml, and the formula may duplicate an existing hyaluronic-acid toner or serum. View the Anua serum.
4. numbuzin No.2 Rose PDRN Collagen 2X Plumping Serum 30 ml
numbuzin has the most structurally busy formula. The brand discloses 10% Rose PDRN, 54% collagen water, 5% niacinamide and 15 peptide types. The INCI also contains multiple humectants, film-forming polymers, hydrolyzed collagen, rose extract, a cooling agent, hydrolyzed sponge, a vitamin C derivative and resveratrol. Its jelly texture and quarter-sized use direction distinguish it from a conventional few-drop serum.
Best fit: someone who actively wants a bouncy jelly texture, cooling sensation and peptide-heavy formula. Limitation: hydrolyzed sponge and Methyl Diisopropyl Propionamide make it a poor default for a person seeking the simplest formula. The disclosed percentages are not directly comparable pure-active doses. View the numbuzin serum.
5. Medicube PDRN Pink Peptide Serum 30 ml
Medicube combines Sodium DNA with niacinamide, glycerin-rich hydration, isopropyl myristate, hydrolyzed collagen and a five-peptide group. The original salmon-DNA formula and the newer Rose PDRN formula are both displayed on the brand page. The ProtoClinical title does not name the Rose variant, so this comparison uses the original formula and records the version issue in the ledger.
Best fit: a buyer who wants a dewy, peptide-rich dropper serum and knows the exact package version being ordered. Limitation: fragrance appears in both official formula lists even though a free-from block says fragrances are excluded. The INCI takes priority. View the Medicube serum.
6. COSRX 5PDRN Collagen Intense Vitalizing Serum 100 ml
COSRX delivers the broadest volume value and a practical pump. The formula combines Sodium DNA and hydrolyzed DNA with niacinamide, betaine, panthenol, hydrolyzed collagen, allantoin, alpha-arbutin, Centella asiatica, a peptide and multiple hyaluronic-acid forms. It is a lightweight, fast-absorbing serum rather than a rich emulsion. No fragrance is listed, although t-Butyl Alcohol appears low in the ingredient list.
Best fit: consistent users who want a large hydrating serum and can finish 100 ml. Limitation: “5 PDRN” is a branded formula concept, not five disclosed concentrations of Sodium DNA. The formula may overlap with niacinamide, alpha-arbutin and hyaluronic-acid products already owned. View the COSRX serum.
7. Abib PDRN Glow Serum 4.0 Pump 30 ml
Abib makes the strongest transparency-and-packaging case. The brand discloses 4% PDRN and states that the PDRN raw material has 90% purity. Sodium DNA appears sixth in the INCI, followed by humectants, niacinamide, panthenol, beta-glucan, hyaluronic acid, hydrolyzed collagen and several peptides. The airless pump reduces repeated air exposure and gives more controlled dispensing than an open dropper.
Best fit: a buyer willing to pay more for a disclosed concentration, focused formula and airless dispensing. Limitation: it costs about $1 per ml, and Abib warns that the marine-derived PDRN has a noticeable inherent odor even though no added fragrance is listed. View the Abib serum.
8. IOPE Expert PDRN Caffeine Shot Serum 30 ml
IOPE is the most specialized product. The brand discloses 38% of its plant-derived Bio-PDRN proprietary complex and 20,000 ppm caffeine, which equals 2%. The INCI starts with Lactobacillus ferment lysate, followed by water, propanediol, glycerin, niacinamide, butylene glycol and caffeine. Beta-glucan and Acetyl Tetrapeptide-11 support the hydration and cosmetic firmness positioning. No fragrance is listed.
Best fit: a buyer who specifically wants a caffeine-focused, fast-absorbing gel serum and accepts premium pricing. Limitation: 38% Bio-PDRN refers to a proprietary plant-derived complex, not 38% pure Sodium DNA, so it cannot be compared directly with Abib’s 4% disclosure or numbuzin’s Rose PDRN percentage. View the IOPE serum.
Formula name versus complete formula
The word PDRN does not tell you how a serum will feel or what else it will do. Beauty of Joseon and MEDIHEAL include meaningful emollients. Anua and COSRX are dominated by humectant systems. numbuzin relies on a jelly network, collagen-water positioning, peptides and unusual sensory ingredients. Medicube combines peptides with a richer emollient and film-forming base. Abib emphasizes disclosed Sodium DNA and pump protection. IOPE is built around a ferment-rich proprietary complex and caffeine.
Concentration labels require context. Four percent PDRN, 10% Rose PDRN and 38% Bio-PDRN are not interchangeable unless each brand defines material, purity, carrier and assay in the same way. The fair comparison is to record exactly what each brand discloses, avoid converting proprietary complexes into pure-active percentages, and judge the full INCI, package and routine fit.
Price per ml versus cost per use
| Product | 0.15 ml/use | 0.25 ml/use | 0.35 ml/use | Estimated uses at 0.25 ml |
|---|---|---|---|---|
| Beauty of Joseon | $0.10 | $0.17 | $0.23 | 120 |
| MEDIHEAL | $0.09 | $0.15 | $0.21 | 160 |
| Anua | $0.16 | $0.27 | $0.38 | 120 |
| numbuzin | $0.14 | $0.23 | $0.32 | 120 |
| Medicube | $0.13 | $0.22 | $0.30 | 120 |
| COSRX | $0.03 | $0.06 | $0.08 | 400 |
| Abib | $0.15 | $0.25 | $0.35 | 120 |
| IOPE | $0.25 | $0.41 | $0.58 | 120 |
A quarter-sized amount, as directed for the numbuzin jelly serum, may be much larger than 0.25 ml. One to two pumps also varies by package. Use the table for relative economics, not an exact empty-bottle date.
Best option for each profile
For strict budget and high usage: COSRX. For a compact lower-cost bottle: Beauty of Joseon. For dry-feeling skin and pump convenience: MEDIHEAL. For fragrance avoidance and dewy hydration: Anua. For a dense jelly and peptide-heavy routine: numbuzin, provided cooling and hydrolyzed sponge are acceptable. For a familiar pink peptide serum: Medicube, after confirming the package formula. For disclosed concentration and airless dispensing: Abib. For caffeine: IOPE.
Routine compatibility should settle close decisions. A serum usually follows cleanser and toner, then precedes moisturizer and sunscreen. A hydrating PDRN serum does not require a second hyaluronic-acid serum, a collagen serum, another peptide serum and a separate glow essence in the same routine. One coherent serum used consistently is usually a better purchase than several products with overlapping jobs.
When paying more can make sense
Paying more can be rational for a differentiated formula that will actually be used. Abib offers concentration disclosure and an airless pump. IOPE offers a quantified caffeine level and plant-derived proprietary complex. Anua offers a fragrance-free capsule-serum format with several hyaluronic-acid forms. Those differences can justify cost when they match a defined need, but they do not prove superior cosmetic results for every buyer.
When the cheapest product is not the best deal
COSRX has the lowest price per ml, but a 100 ml bottle is not automatically sensible for an occasional user. MEDIHEAL is economical, but its aromatic oils may conflict with a fragrance-avoidant routine. Beauty of Joseon is the lowest-cost 30 ml option, but a buyer focused on caffeine or a disclosed percentage would be paying for the wrong feature set. Value falls when a product duplicates an existing step, causes sensory friction or remains unfinished.
Limitations
This is a retail and formula comparison, not a clinical efficacy ranking. Prices and inventory can change. Brand-disclosed percentages may refer to proprietary complexes or raw-material blends and cannot always be normalized. Texture descriptions come from official pages where available. Ingredient lists can change by region or production run, so the physical package should be checked, especially for the Medicube formula version.
Topical cosmetic serums should not be treated as equivalents to injections, professional procedures or medicines. Reasonable expectations include hydration, a smoother or plumper-looking finish, glow, improved comfort and a better-fitting routine when the complete formula suits the user. Permanent pore reduction, tissue regeneration, treatment of disease and guaranteed collagen rebuilding are outside this comparison.

Frequently asked questions
Which PDRN serum is the best value?
COSRX has the lowest current price per ml because it contains 100 ml at a price close to several 30 ml bottles. Beauty of Joseon is the lowest-cost 30 ml option. The better purchase depends on formula fit and whether the larger bottle will be finished.
Does a higher PDRN percentage mean a better serum?
Not by itself. Percentages may describe different proprietary complexes, raw materials or purity levels. Compare the definition of the percentage, full INCI, package, texture and supporting ingredients.
Which options avoid added fragrance?
Beauty of Joseon, Anua, COSRX, Abib and IOPE do not list parfum or fragrance in the official ingredient lists reviewed. MEDIHEAL includes rose and cypress aromatic oils. Medicube lists fragrance. numbuzin contains rose extract, raspberry ketone and a cooling agent.
Which PDRN serum is best for dry-feeling skin?
MEDIHEAL has the clearest emollient profile with squalane, cetyl ethylhexanoate and caprylic/capric triglyceride. Beauty of Joseon also includes squalane and ceramide NP. Anua is humectant-led and may still need a moisturizer in dry conditions.
Can I use a PDRN serum with peptides or collagen?
Many products here already contain peptides or hydrolyzed collagen. Adding separate products is optional and can create redundant layers. Evaluate the complete formula and how it behaves under moisturizer and sunscreen.
How much PDRN serum should I apply?
Follow the specific package directions. Brands recommend anything from a few drops to one or two pumps or a quarter-sized amount. The 0.15 ml, 0.25 ml and 0.35 ml figures shown here are economic scenarios only.
Final verdict by profile
Choose COSRX for maximum volume value, Beauty of Joseon for the most economical compact bottle, MEDIHEAL for squalane-rich emollience, Anua for fragrance-free dewy hydration, numbuzin for a high-sensory jelly and peptide formula, Medicube for a dewy peptide serum after formula-version verification, Abib for disclosed 4% PDRN and airless packaging, and IOPE for a targeted caffeine formula. The strongest purchase matches an existing routine rather than the loudest PDRN claim.
