Science, Safety, Results & Doctor-Led Care in Delhi, India
Aesthetic medicine is increasingly moving toward regenerative treatments that focus on skin quality rather than short-term cosmetic change. One such option is Salmon DNA (polynucleotide) treatment, an injectable therapy studied for its potential to support hydration, skin repair, texture and resilience over time.
Importantly, salmon DNA treatment is not a filler or a volumising procedure. It is best suited for patients seeking gradual skin-quality improvement—smoothness, elasticity and resilience—rather than instant lifting or contour change.

Doctor Summary — Salmon DNA / Polynucleotide Treatment
Salmon DNA treatment, also referred to as polynucleotide (PN) therapy, is a regenerative skin treatment using purified DNA fragments commonly sourced from salmon. Research suggests these polynucleotides may support cellular repair, collagen-related processes, hydration and skin-barrier recovery, which is why the treatment may be considered for dull, dehydrated, ageing or compromised skin.
A treatment course commonly involves 2–3 sessions, around 3–4 weeks apart, although some formulations follow a different schedule. Improvement is gradual and is best judged across the full course rather than after one session. Results are subtle and vary by skin condition.
When performed in a doctor-led clinic, salmon DNA treatment is generally well tolerated in suitable patients. It is still an injectable procedure, so clinical suitability, product authenticity and possible side effects are assessed before treatment.

What Is Salmon DNA (Polynucleotide) Treatment?
Salmon DNA treatment refers to the medical use of polynucleotides (PN)—biologically active DNA fragments extracted and purified from salmon sources—to support skin repair and regeneration.
These purified DNA fragments are studied in dermatology for their potential to:
- Support tissue repair
- Improve cellular hydration
- Enhance skin elasticity and texture
- Strengthen the skin barrier
Rather than altering facial structure, salmon DNA therapy focuses on long-term skin quality improvement.
How Polynucleotides Work on the Skin (The Science)
Polynucleotides are thought to work by supporting the skin’s own regenerative processes rather than forcing immediate cosmetic change.
Key Biological Actions
Research suggests polynucleotides may support the following processes, although results vary between formulations and patients:
- Fibroblast activation, encouraging collagen and elastin production
- Extracellular matrix repair, improving firmness and resilience
- Cellular hydration signalling, enhancing long-term moisture retention
- Skin-barrier recovery, reducing sensitivity and environmental stress
This biological mechanism places salmon DNA therapy within regenerative dermatology, a field focused on restoring healthy skin function over time.
Who Is an Ideal Candidate for Salmon DNA Treatment?
Salmon DNA treatment may be considered for individuals who:
- Have dull, dehydrated, or fatigued-looking skin
- Are experiencing early signs of ageing or textural changes
- Have acne-affected or post-inflammatory skin
- Want gradual, natural skin rejuvenation
- Are not ready for fillers or surgical procedures
A doctor-led consultation is essential to assess suitability and define realistic expectations.
Areas Treated with Polynucleotide Therapy
Polynucleotide skin treatment can be used in:
- Face (overall skin quality and texture)
- Under-eye area (for skin quality, not volume correction)
- Neck and décolletage
- Hands
- Acne-affected or compromised skin
Treatment protocols are individualised based on anatomical area and skin biology.
Polynucleotides (PN) vs PDRN — Understanding the Difference
Both polynucleotides (PN) and PDRN-based skin treatments are commonly derived from salmonid DNA but differ in molecular structure and clinical use.
PN vs PDRN in Clinical Practice
- Polynucleotides (PN): Longer DNA chains, commonly selected for hydration, elasticity, and overall skin-quality improvement
- PDRN: Shorter DNA fragments, often chosen for repair-focused or inflammatory skin concerns
The choice depends on skin condition, treatment goals, and medical assessment, not marketing terminology.

At The Face Clinic, salmon DNA treatment follows a structured medical protocol:
- Detailed skin assessment and diagnosis
- Selection of an appropriate polynucleotide formulation
- Delivery via micro-injections, mesotherapy, or combination techniques
- Typical session duration of 30–45 minutes
Protocols are customised based on skin condition, treatment area, and patient profile.
Results Timeline — What to Expect
Salmon DNA treatment delivers gradual improvement rather than instant transformation.
Some patients notice early changes in hydration and freshness within a few weeks. Where texture and resilience improve, the change develops gradually over the following weeks to months and is best judged across the full treatment course. The timing and degree of improvement vary by formulation, treatment area and starting skin condition.
Further treatment is planned based on how the skin responds, rather than on a fixed maintenance timetable.
Downtime, Aftercare & Recovery
Downtime is usually minimal and may include:
- Mild redness or swelling at injection sites
- Temporary skin sensitivity
Patients are advised to:
- Avoid strenuous exercise for 24 hours
- Avoid heat exposure immediately post-treatment
- Follow doctor-recommended skincare protocols
Most individuals resume normal activities shortly after treatment.
Safety, Side Effects & Who Should Avoid Treatment
When performed in a doctor-led medical clinic, salmon DNA treatment is generally well tolerated in suitable patients. The evidence for polynucleotide treatments is encouraging but still developing, and results vary between formulations and patients.
Possible Side Effects
- Mild bruising or swelling
- Temporary redness
- Rare inflammatory reactions
Contraindications & Clinical Caution
Salmon DNA treatment may not be suitable for:
- Pregnant or breastfeeding individuals
- Active skin infections or inflammation
- Known fish allergies
- Certain autoimmune or immunosuppressed conditions
- Patients on anticoagulant therapy or with a history of keloid formation
Regulatory status and approved usage vary internationally; product authenticity and provider credentials must always be verified.
