PDRN is an ingredient used in some Korean skincare products, including serums, creams, toners and masks. Short for polydeoxyribonucleotide, PDRN refers to DNA-derived fragments that are being studied for their potential role in skin repair and regeneration.
So, what does PDRN do for skin? In topical skincare, it is commonly included in formulations designed to support hydrated, smoother-looking skin. However, the available research is still developing, and results from specific studies should not be treated as proof that every PDRN serum or cream will produce the same effects.
In this guide, we explain what PDRN is, its potential skincare benefits, what current research tells us, how to use topical PDRN and what to consider when choosing a Korean PDRN product.
What Is PDRN in Skincare?
PDRN stands for polydeoxyribonucleotide. It refers to fragments of DNA that have been studied for their potential biological effects, including their possible role in processes associated with tissue repair.
Some PDRN preparations are derived from fish DNA, including salmon. However, the source and characteristics of PDRN can vary depending on how the ingredient is obtained and prepared.
In Korean skincare, PDRN is used in cosmetic formulations such as serums, creams and masks. These products are generally marketed to support smoother, hydrated and healthier-looking skin.
It is important to distinguish between research involving specific PDRN preparations and the performance of finished skincare products. Findings from laboratory studies or medical applications do not automatically demonstrate that every topical PDRN product will deliver the same effects.
Is PDRN made from salmon DNA?
Some PDRN preparations are derived from salmon or other fish DNA. This is why PDRN is often associated with salmon DNA in Korean skincare discussions.
However, not every ingredient described as PDRN necessarily comes from the same source. The origin and characteristics of an ingredient depend on the specific preparation and manufacturer.
If you want to know whether a skincare product contains fish-derived PDRN, check the manufacturer's ingredient information or contact the brand directly. If you have a fish allergy, do not assume that topical application is safe simply because the ingredient is used in skincare. Seek professional advice if you are unsure.
Is PDRN the same as polynucleotides?
PDRN and polynucleotides (PN) are related DNA-derived materials, but the terms should not be treated as interchangeable.
They can differ in characteristics such as molecular size, composition, preparation and intended application. Both are discussed in skincare and aesthetic treatments, particularly in relation to skin quality and repair-related processes.
When researching PDRN or polynucleotide skincare, it is important to consider the specific ingredient and formulation being used. Research involving one preparation does not automatically establish the effectiveness of another.
For consumers, the ingredient name alone is not enough to determine how a finished product will perform. Consider the complete formulation, its intended use and the evidence available for that particular product.
What Are the Potential Benefits of PDRN for Skin?
PDRN is being investigated for several potential skin-related applications, including processes associated with tissue repair, skin texture and visible signs of ageing. However, the evidence varies according to the PDRN preparation, how it is administered and the outcomes measured.
1. Supporting processes associated with skin repair
PDRN has attracted research interest because certain preparations have been studied for their effects on biological pathways involved in tissue repair.
Much of this research relates to medical applications, laboratory investigations and specialised formulations. These findings help explain the interest in PDRN, but they do not establish that an ordinary cosmetic serum can heal wounds or regenerate damaged skin.
For everyday skincare, it is more accurate to describe PDRN as an ingredient being investigated for its potential role in skin-related processes rather than a proven skin-repair treatment.
2. Supporting smoother-looking skin
PDRN is included in some cosmetic formulations marketed towards people concerned about uneven texture and visible signs of ageing.
However, the effect of a finished product depends on its complete formulation, how it is used and individual skin characteristics. Other ingredients may also contribute to improvements in the appearance of skin.
A product containing PDRN should therefore be evaluated as a complete formulation rather than on the featured ingredient alone.
3. Supporting a hydrated, plumper-looking complexion
Some PDRN skincare products combine the ingredient with moisturising and hydrating ingredients such as hyaluronic acid.
Hyaluronic acid is a humectant that helps attract and retain water in the outer layers of the skin. This can temporarily improve the appearance of dryness and fine dehydration lines.
A PDRN product containing effective moisturising ingredients may therefore help support a more hydrated-looking complexion. However, these benefits should not automatically be attributed to PDRN itself.
4. Addressing visible signs of ageing
PDRN is also being investigated in relation to skin elasticity, collagen-related processes and the appearance of wrinkles.
Some research has reported promising findings for specific preparations and applications. However, this does not establish that all topical PDRN products can reduce fine lines or improve skin firmness.
If your main concern is visible skin ageing, consider your overall skincare routine, including regular moisturising, daily sun protection and suitable evidence-informed ingredients.
The takeaway: PDRN is an interesting area of skincare research, but evidence for topical cosmetic products is still developing. The presence of PDRN on an ingredient list is not a guarantee of a particular result.
What Does the Research Say About Topical PDRN?
Research into PDRN includes laboratory investigations, animal studies, medical applications and emerging research into topical cosmetic formulations. These different types of evidence should not be treated as equivalent.
A 2025 narrative review published in the Journal of Skin and Stem Cell examined PDRN and its potential dermatological and cosmetic applications. It discussed research relating to wound healing, skin ageing, acne scars, pigmentation and hair regeneration. However, the review included preclinical and clinical studies involving different PDRN preparations and methods of administration. Its findings provide an overview of the research landscape, rather than proof that ordinary topical cosmetic products deliver all the effects discussed.
A 2026 study published in PLOS ONE investigated a specific medium-length PDRN preparation, known as PDRN-850K, in laboratory models, skin tissue models and a human clinical study. The clinical component was a randomised, double-blind, split-face study involving 31 women aged 35 to 55. It compared a 0.1% PDRN-850K eye cream with a 0.1% retinol eye cream over 28 days. The researchers reported greater improvements in several measured periocular skin parameters on the PDRN-treated side. However, these findings relate to the particular PDRN preparation and formulation tested. The relatively small sample and short study duration should also be considered. The results do not establish that all topical PDRN products produce the same outcomes or that PDRN is generally more effective than retinol.
For readers who want to explore the research:
- 2025 review: Polydeoxyribonucleotide in Skincare and Cosmetics
- 2026 topical PDRN study published in PLOS One
- Additional PDRN and polynucleotide research
When evaluating PDRN research, consider the preparation studied, concentration, delivery method, study design, duration and outcomes measured.
Evidence involving injectable treatments, animal studies or specialised research formulations cannot automatically be applied to ordinary cosmetic skincare. Similarly, findings from one finished product do not establish the effectiveness of every product containing PDRN.
Is Topical PDRN the Same as Injectable PDRN?
No. Topical PDRN skincare and injectable PDRN treatments are different in how they are administered, their intended applications and the evidence used to evaluate them.
Topical PDRN is found in cosmetic products such as serums, creams and masks. These products are applied to the skin's surface and are formulated for use as part of a skincare routine.
Injectable PDRN involves administration through a clinical procedure. These treatments should be assessed and performed by appropriately qualified healthcare professionals, with suitability determined on an individual basis.
The skin acts as a protective barrier, and the effects of a topical ingredient depend on factors such as its characteristics, formulation and delivery. Applying PDRN to the skin is therefore not equivalent to administering it through an injection.
For this reason, a topical PDRN serum should not be expected to produce the same results as an injectable treatment. Research involving medical procedures cannot automatically be used as evidence that an over-the-counter cosmetic product will deliver equivalent effects.
If you are considering PDRN for your home skincare routine, choose a cosmetic product according to its complete formulation, intended use and manufacturer's instructions.
Is PDRN Suitable for Acne-Prone Skin?
PDRN may be included in a skincare routine for acne-prone skin, but its presence in a product does not automatically make the formula suitable for everyone.
When choosing a PDRN product, consider the complete ingredient list, texture and your skin's individual tolerance. Lightweight serums may appeal to people who prefer less-rich formulations, while others may benefit from a more moisturising product.
It is important to understand that PDRN is not an established stand-alone acne treatment. If active breakouts are your main concern, prioritise skincare ingredients and treatments with evidence for acne management. Persistent, painful or severe acne may require assessment by a dermatologist or another suitably qualified healthcare professional.
For practical advice on building a routine, read our guide to Korean skincare for acne-prone skin in South Africa.
Can PDRN Help with Acne Marks or Scars?
Acne marks and acne scars are different skin concerns and should not be treated as interchangeable.
Post-acne marks are areas of discolouration that can remain after a breakout. These may include dark marks associated with post-inflammatory hyperpigmentation. True acne scars involve changes to the skin's texture, such as indentations or raised areas.
Although PDRN is being investigated for its potential role in skin-related repair processes, there is not enough evidence to conclude that topical cosmetic PDRN products can reliably remove acne scars or fade post-acne pigmentation.
For lingering dark marks, a suitable skincare routine, consistent sun protection and evidence-informed ingredients may help improve the appearance of uneven skin tone over time. Indented or raised acne scars may require professional assessment and treatments tailored to the type of scarring.
Choose products according to the specific concern you want to address rather than assuming that one ingredient can address every type of post-acne change.
Is PDRN Suitable for Sensitive or Dehydrated Skin?
Whether a PDRN product is suitable for sensitive or dehydrated skin depends on the complete formulation and your individual skin tolerance.
PDRN for Dehydrated Skin
If your skin feels tight, uncomfortable or looks dull because of dehydration, consider the product's moisturising ingredients as well as its featured actives.
Ingredients such as glycerin and hyaluronic acid are humectants that help attract water to the outer layers of the skin. A suitable moisturiser can also help reduce moisture loss and support skin comfort.
A PDRN product containing these ingredients may fit into a hydrating routine, but the moisturising benefits should be assessed in the context of the complete formula.
PDRN for Sensitive Skin
If your skin is sensitive or easily irritated, pay attention to the entire ingredient list rather than focusing only on PDRN.
Consider fragrance, exfoliating acids, retinoids and other active ingredients that may affect your skin's tolerance. Introduce new products gradually and patch-test before incorporating them into your regular routine.
Stop using a product if you experience persistent burning, itching, swelling or irritation. Seek professional advice if symptoms are significant or do not settle.
If you have a known fish allergy and a product may contain fish-derived ingredients, contact the manufacturer for clarification before use.
How to Use PDRN in Your Korean Skincare Routine
If you choose a topical PDRN toner, serum or cream, follow the application instructions provided by the manufacturer. The appropriate frequency and application method depend on the specific formulation. Not every PDRN product is intended for twice-daily use.
In general, apply skincare products from lighter to richer textures, while following any product-specific instructions.
Morning Routine:
A simple morning skincare routine incorporating a PDRN product could include:
- Gentle cleanser: Cleanse your face without leaving your skin feeling tight or stripped.
- PDRN product: Apply your chosen toner, serum or cream according to its instructions and texture.
- Moisturiser: Apply a moisturiser suited to your skin type and hydration needs.
-
Sunscreen: Finish with broad-spectrum sunscreen of at least SPF 30. Apply generously and reapply as directed.
Evening Routine:
A simple evening routine incorporating a PDRN product could include:
- Cleanser: Remove sunscreen, makeup and daily impurities. If needed, use an appropriate first cleanser followed by a gentle water-based cleanser.
- PDRN product: Apply your chosen product according to the manufacturer's instructions.
- Moisturiser: Finish with a suitable moisturiser to help maintain skin comfort and hydration.
If you use several serums or treatment products, introduce them gradually rather than adding everything at once. Pay attention to how your skin responds and adjust your routine if irritation develops.
Remember that a longer skincare routine is not necessarily a more effective one. Consistency and choosing products suited to your skin are more important than the number of steps.
Can You Use PDRN With Other Skincare Ingredients?
PDRN can appear alongside other skincare ingredients in a routine, but compatibility depends on the complete formulation, how products are used and your skin's individual tolerance.
Before combining products, consider their active ingredients, application instructions and your existing routine.
PDRN and Hyaluronic Acid
Hyaluronic acid is a humectant that helps attract water to the outer layers of the skin. A skincare formula containing both PDRN and hyaluronic acid may appeal to people looking for a more hydrated, plump-looking complexion.
The hydrating effect will depend on the complete formulation, including its moisturising ingredients.
PDRN and Niacinamide
Niacinamide is a versatile skincare ingredient used to support the skin barrier and improve the appearance of uneven skin tone.
A niacinamide product can generally be used in the same routine as a PDRN product if both formulations suit your skin. Introduce new products gradually, particularly if you have sensitive skin.
PDRN and Retinol or Retinal
Retinol and retinal are vitamin A derivatives commonly used in skincare to address visible signs of ageing and other skin concerns.
If you already use a retinoid, you can consider incorporating a PDRN product into your routine, provided the individual product instructions allow it. Introduce changes gradually so you can identify the cause if irritation develops.
Do not assume that PDRN makes retinoids more effective or prevents retinoid-related irritation.
PDRN and Exfoliating Acids
Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are exfoliating ingredients used in skincare to improve the appearance and feel of skin texture.
If your routine already includes exfoliating acids, introduce additional products gradually and monitor your skin's response. Combining several active products does not necessarily improve results and may increase the risk of irritation.
If persistent irritation develops, simplify your routine and allow your skin to recover before introducing additional products.
How to Choose a PDRN Skincare Product
When shopping for PDRN skincare, look beyond the ingredient highlighted on the packaging. The complete formulation, intended use and manufacturer's instructions all matter when deciding whether a product is suitable for your routine.
1. Choose a Format That Suits Your Routine
PDRN is featured in different skincare formats, including serums, toners, creams, masks and toner pads. Each format has a different texture and intended place in a skincare routine.
Choose a product that fits comfortably into your existing routine and suits your preferences. A serum is not automatically more effective than a toner or cream simply because of its format.
2. Check the Complete Ingredient List
Look at the full formulation, including moisturising ingredients, fragrance and other active ingredients.
The featured ingredient alone does not tell you how a product will feel, how it should be used or whether it will suit your skin. Consider the complete ingredient list, particularly if your skin is sensitive or you already use several active ingredients.
3. Match the Product to Your Main Skin Concern
Consider what you want your skincare routine to address.
- Dehydrated skin: Look for suitable humectants and moisturising ingredients, such as glycerin and hyaluronic acid.
- Uneven skin tone: Consider evidence-informed ingredients formulated to address the appearance of pigmentation.
- Acne-prone skin: Prioritise products and treatments with evidence for acne management rather than relying on PDRN alone.
- Visible signs of ageing: Consider your overall routine, including moisturising and consistent sun protection.
Choose a product according to its complete formulation and intended purpose rather than expecting PDRN to address every skin concern.
4. Be Realistic About the Evidence
Be cautious of claims that a topical cosmetic product can regenerate skin, erase acne scars or deliver results equivalent to injectable treatments.
Also remember that a higher advertised PDRN concentration does not automatically establish that a product will be more effective. The preparation, formulation and available evidence all matter.
A credible product description should explain what the formulation is intended to do without promising guaranteed results.
5. Check the Product Instructions and Availability
Before purchasing, read the manufacturer's directions, review the product details and check the current product listing.
Pay attention to the recommended application frequency, any usage precautions and the complete ingredient information. Product formulations, ranges and stock availability can change, so check the latest listing before ordering.
