The short answer to whether PDRN and salmon DNA do the same thing: for the most part, yes, because they usually refer to the same ingredient. PDRN (polydeoxyribonucleotide) is the scientific name for fragments obtained from fish-derived DNA, while “salmon DNA” is the everyday name for the same treatment. Because the brand, purity and fragment structure of a product can vary, the doctor who examines your skin decides which one suits you.
What is a polynucleotide, and how does it relate to salmon DNA
Polynucleotide is the general name for the long chains formed by the nucleotide units that make up DNA. PDRN sits within this broad family: it is DNA broken into small fragments and purified. The name salmon DNA comes from the fact that these fragments are obtained from fish, most often salmon or trout species.
For this reason, the trio “salmon DNA, PDRN and polynucleotide” does not always mean exactly the same thing. Polynucleotide is a wider term; PDRN and salmon DNA, in everyday conversation, usually describe the same injection. Since fragment size and processing method can differ between some products, it is sensible to ask your doctor which product will be used.
How the terms PDRN and salmon DNA are used
In clinical language the term is “PDRN”, while on social media and in search engines “salmon DNA” is more common. Both describe a skin renewal treatment aimed at skin quality, hydration and radiance. Neither is meant to add volume or create contour.
It also helps to know the limits of the scientific evidence. PDRN has studies on tissue repair; however, in aesthetic use the results vary from person to person and the effects are not lasting. It is wise to be cautious about descriptions that make exaggerated promises.
Meso PDRN: application in the style of mesotherapy
Meso PDRN means giving a PDRN-containing product with the logic of mesotherapy, that is, with fine needles, in small amounts and at many points in the superficial layers of the skin. The procedure is carried out under a doctor’s control; the target area is cleaned, and injections are applied to planned areas such as the face, neck or around the eyes.
After the procedure, temporary redness, mild swelling or needle marks may be seen. The number of sessions and the interval between them are planned by the doctor according to the condition of your skin.

The difference between salmon DNA and gold needle
Salmon DNA is a substance application; gold needle, in general use, refers to a microneedling device that delivers radiofrequency energy. In other words, one injects an ingredient into the skin, while the other aims to trigger the skin’s own renewal response through heat delivered from the needle tips and micro-injury.
In practice, when firmness, pores and texture irregularities are the main concern, device-based methods come into play. When hydration, radiance and fine skin structure are the priority, PDRN is discussed more often. The two can be planned in the same session or at different times, but the doctor decides this after assessing your skin.
Does salmon DNA replace filler
No, salmon DNA is not a filler and does not take its place. Filler makes up for volume loss and gives contour to areas such as the jawline, lips or cheeks. Salmon DNA adds no volume; it focuses on skin quality.
If you have sagging, volume loss or a clear proportion concern in your face, the topic to discuss is filler; for details you can take a look at our filler treatments page. If your skin looks tired, dull and dry, PDRN may be a more logical starting point. In some people the two are planned together.
Do PRP and salmon DNA answer different needs
Partly, yes. PRP is platelet-rich plasma obtained from a person’s own blood; its source is the person’s own body. PDRN, on the other hand, is fish-derived. Both are used for skin renewal, but their contents and the way they are prepared are different.
For PRP, blood is drawn and processed; PDRN is a ready-made product. For someone with a fish allergy, PRP may naturally be the more suitable option. Which one fits you is determined by your skin structure, your expectations and your health history. You can look at our PRP page for PRP details.
Comparison of PDRN, PRP and filler
| Treatment | Source | Main goal |
|---|---|---|
| PDRN / salmon DNA | Fish-derived DNA fragments | Skin quality, hydration, radiance, renewal of fine skin texture |
| PRP | The person’s own blood | Skin renewal and revitalization |
| Filler | Volumizing filler material | Volume and contour |
| Gold needle | Radiofrequency microneedling device | Skin texture and the look of firmness |
Which treatment is considered for which skin need
- Dull, dry, tired-looking skin: PDRN or PRP is discussed.
- Fine lines and texture irregularities: PDRN, PRP or device-based methods are evaluated.
- Thin, tired-looking under-eye area: the doctor evaluates mesotherapy approaches suited to the area.
- Volume loss, jawline or lip contour: filler comes into play.
- Laxity and a wish for firmness: device-based treatments and filler can be considered together.
Who should not have the treatment, and what to watch for
People with an allergy to fish or fish products, those with an active infection, widespread acne or skin inflammation in the treatment area, and those who are pregnant or breastfeeding should definitely talk to a doctor before treatment. Medications taken regularly, especially blood thinners and drugs that affect the skin such as isotretinoin, should also be taken into account.
Possible side effects include redness, swelling, bruising and needle marks; these are mostly temporary. Following the aftercare advice given by your doctor makes the process easier.
Doctor assessment before you decide
The similarity of the names can be confusing, but the decision should be based on your skin’s needs, not on names seen on social media. Özel Demiderm Polikliniği was founded in 2003 on the principle of “health first” and serves in Konak, İzmir. The medicines you use and your general condition are assessed before treatment by the medical aesthetics team, which includes Dr. Özlem Şahan. Clients coming from Bornova, Karşıyaka, Buca and Bayraklı are also served.
For a more detailed comparison of the three treatments, see our article on the difference between Salmon DNA, PRP and PDRN, and for the treatment the clinic offers, see the Somon DNA page. If you would like to talk about which one is right for your skin, you can reach us through our contact page.
