PDRN injections: salmon DNA to support skin repair.
If your skin is feeling tired, dull or showing signs of ageing, PDRN may be the gentle skin-repairing treatment you’ve been looking for.
What is a PDRN injection?
Salmon DNA fragments to support skin repair.
PDRN injections use fragments of DNA derived from salmon, a source known for its biocompatibility with human skin. Placed in the superficial layer of the skin, these molecules help support its natural healing and regeneration process, to improve skin quality from within.
PDRN stands for polydeoxyribonucleotide. It is often recommended when skin has become dull, sensitive or weakened over time, and some people use it to maintain skin health as part of a long-term skincare routine.
If you are comparing it with our PN injectable (polynucleotides from Italian trout), the FAQ below sets out how the two differ. Your doctor will explain which one suits your skin.
- Salmon DNA — fragments known for their biocompatibility with skin
- Skin repair — supports natural healing and regeneration
- Superficial — tiny injections by fine needle or injector gun
- Minimal downtime — most people resume daily activities quickly
How it works
How do PDRN injections work?
PDRN places fragments of salmon DNA in the superficial layer of the skin, where they help support its natural healing and regeneration process. Over a course of treatments, the aim is better skin quality (texture, elasticity, hydration and radiance) rather than instant volume.
Supports repair and regeneration
These molecules help support your skin’s natural healing and regeneration process, improving skin quality from within.
- Supports skin repair and regeneration
- Improves skin texture and elasticity
- Helps reduce the appearance of fine lines
- Improves skin hydration and radiance
Fine needle or injector gun
Tiny injections place PDRN in the superficial layer of the skin, by fine needle or injector gun. The procedure is relatively quick and well tolerated, and a numbing cream is usually applied first.
A course, then maintenance
Usually 3–4 sessions at 3–4 week intervals, depending on your skin condition, then 1 session every 6 months to maintain skin health.
Personalised assessment
Who is PDRN recommended for?
PDRN is often recommended for skin that looks tired or dull, feels sensitive, or is showing early signs of ageing. Your doctor assesses your skin first to confirm PDRN suits your concerns and whether another treatment should be added.

Dull or uneven skin tone
Skin that looks tired or dull, whether it is dry or oily, or has an uneven tone.
-
Fine lines & early ageing
Fine lines or early signs of ageing, as PDRN improves skin texture and elasticity.
-
Acne scarring & enlarged pores
Acne scarring and enlarged pores, where supporting skin repair helps improve texture.
-
Sensitive or weakened skin
Skin that has become more sensitive or weakened over time.
-
Long-term skin health

Your treatment journey
Detailed consultation. Gentle injections. Planned maintenance.
-
Consult
We begin with a detailed consultation to assess your skin’s needs and decide whether PDRN, alone or with other treatments, suits you.
-
Prepare
Topical anaesthesia (numbing cream) is applied to minimise discomfort.
-
Treat
PDRN is administered into the superficial layer of the skin with an injector gun or fine needle. The visit takes around 45 minutes, including numbing.
-
Recover
Tiny bumps or mild redness usually subside within a few hours to a day or two. Sessions are 3–4 weeks apart, then every 6 months for maintenance.
Safety & expectations
Suitability comes first: a detailed consultation assesses your skin’s needs before any PDRN injection.
Tiny bumps or mild redness at the injection sites are expected and usually settle within a few hours to a day or two. Tell your doctor about any fish allergy, medicines, skin conditions or recent treatments.
PDRN Injectable (Salmon DNA): frequently asked questions
What is a PDRN injection made from?
A PDRN injection is made from polydeoxyribonucleotide (PDRN): salmon-derived DNA fragments, from a source known to be biocompatible with human skin. Injected into the superficial layer of the skin, these molecules help support its natural healing and regeneration process.
How many PDRN sessions do I need?
A course of 3–4 PDRN sessions at 3–4 week intervals is usually advised, depending on your skin condition, followed by 1 session every 6 months for maintenance. Your doctor will confirm the plan at your consultation.
What can I expect during PDRN treatment?
Topical anaesthesia is applied first to minimise any discomfort, after which PDRN is administered into your skin via an injector gun. The entire treatment takes around 45 minutes, including time for numbing, and is relatively quick and well tolerated.
Is there downtime after a PDRN injection?
Downtime is generally minimal. You might notice tiny bumps or mild redness at the injection sites immediately after PDRN treatment. These typically subside within a few hours to a day or two, so you can return to your daily activities relatively quickly.
Can PDRN help acne scars and enlarged pores?
PDRN is often recommended for acne scarring and enlarged pores, as well as dull or uneven skin tone and skin that has become sensitive or weakened. By supporting skin repair and regeneration, it helps improve texture and elasticity. Your doctor assesses your scars first and may combine PDRN with laser.
What is the difference between PDRN and PN injections?
Both are DNA-derived skin boosters, but they are different products and not interchangeable. Our PDRN injectable uses DNA fragments derived from salmon, given as tiny injections into the superficial layer of the skin, usually as 3–4 sessions 3–4 weeks apart. Our PN injectable uses polynucleotides extracted from Italian trout with patented Highly Purified Technology (HPT), usually as 3 sessions. Your doctor will recommend the one that suits your skin.
Can PDRN be combined with other treatments?
Yes. PDRN can be combined with other aesthetic treatments such as laser or fillers to enhance your results. We begin with a detailed consultation to assess your skin’s needs and determine suitable treatment options, so your plan is personalised.
Who should not have PDRN injections?
Because PDRN is derived from salmon DNA, tell your doctor if you have a fish allergy. Treatment may also be postponed if you are pregnant or breastfeeding or have an active skin infection in the area. Your doctor reviews your medical history, medicines and previous injections before PDRN treatment.
