1️⃣ Salmon DNA

“Salmon DNA” usually refers to PDRN (Polydeoxyribonucleotide) or PN (Polynucleotide) derived from salmon sperm DNA.

Why salmon?
Because salmon DNA is:

Highly biocompatible with human DNA
Low risk of immune reaction
Strongly associated with tissue repair

It’s used in regenerative skin treatments to:

Stimulate fibroblasts
Increase collagen production
Improve wound healing
Enhance skin elasticity
Reduce inflammation

2️⃣ Exosomes

Exosomes are extracellular vesicles — tiny signalling particles released by cells. They:

Carry growth factors
Contain peptides
Include RNA and signalling molecules
Help cells communicate

In aesthetics, exosomes are used to:

Accelerate healing post-microneedling
Improve skin quality
Reduce inflammation
Promote collagen production

🔬 What Happens When You Use Them Topically During Microneedling?

Microneedling creates microchannels (typically 0.25–1.0mm in aesthetic practice).
For approximately 15–30 minutes, the skin's permeability increases.

So you’re using the treatment as a delivery system.

🧬 Topical Salmon DNA

Topically, polynucleotides:

Act mainly as anti-inflammatory agents
Support wound healing
Improve hydration
May stimulate fibroblasts (limited penetration compared to injectables)

🧪 Topical Exosomes

Topical exosomes (real ones, not just marketing serums):

Deliver growth factors
Contain signalling molecules
Potentially enhance healing pathways
May reduce redness/downtime

💡 Potential Benefits of Combining Both

When used together after microneedling:

1️⃣ Enhanced Healing Environment

Microneedling triggers repair, and exosomes signal
Polynucleotides stabilise and rebuild

This may lead to:

Faster visible recovery
Reduced erythema
Less irritation

2️⃣ Better Collagen Cascade Support

Microneedling = collagen induction
Exosomes = growth factor signalling
PDRN = fibroblast stimulation

3️⃣ Improved Skin Quality Over Course

Particularly good for:

Acne scarring
Early ageing
Dehydrated male skin
Barrier-compromised skin

Frequently Asked Questions

Please reach us at hi@edharbourne.uk if you cannot find an answer to your question.

What are salmon-derived exosomes?

Salmon-derived exosomes are regenerative cell-signalling particles sourced from salmon tissue. They contain growth factors, peptides, and biological messengers that help support skin repair, reduce inflammation, and enhance collagen production following treatments such as microneedling.

How are salmon exosomes different from salmon DNA (PDRN)?

Salmon DNA (also known as polynucleotides or PDRN) helps stimulate tissue repair and collagen production.
Exosomes work differently — they act as signalling messengers that “communicate” with skin cells to encourage regeneration.

In simple terms: Polynucleotides rebuild. Exosomes signal.

How do salmon exosomes work with microneedling?

Microneedling creates controlled micro-channels in the skin, triggering a natural healing response. When exosomes are applied during treatment, they can penetrate through these channels and support faster recovery, enhanced collagen stimulation, and improved overall skin quality.

What skin concerns can salmon exosomes help with?

Salmon-derived exosomes may support improvement in:

Fine lines and early ageing
Acne scarring
Uneven skin texture
Dull or tired skin
Inflammation-prone skin

Results vary depending on skin condition and treatment plan.

How many treatments will I need?

Most clients benefit from a course of 3–5 sessions spaced 4 weeks apart. Improvements in skin texture and firmness develop gradually as collagen production increases over time.

Is the treatment safe?

Salmon-derived regenerative ingredients are selected because they are highly biocompatible and well-tolerated. Treatments are performed under UK-registered training, and E50 products are legally sold in the UK via selected distributors. I would never sell or recommend someone or a product without firsthand experience in using them/it myself.
