In 2026, the shift toward regenerative aesthetics has made Salmon DNA injections (often referred to as PDRN or Polynucleotides) a leading choice for those seeking natural skin healing. Unlike traditional fillers that provide instant volume, Salmon DNA works at a cellular level to repair and rejuvenate the skin from within.
What Is Salmon DNA Injection?
What Is Salmon DNA Used in Aesthetic Treatments?
In aesthetics, Salmon DNA refers to Polydeoxyribonucleotide (PDRN) or Polynucleotides (PN). These are DNA fragments extracted from salmon germ cells, which are purified to be highly bio-compatible with human skin.
How Salmon DNA Injection Works on the Skin
Once injected, these DNA fragments act as “building blocks” for skin repair. They stimulate fibroblasts—the cells responsible for structural support—to produce collagen and elastin while activating specific receptors that help protect and repair skin cells damaged by UV radiation.
Benefits of Salmon DNA Injection
Salmon DNA Injection for Skin Texture Improvement
One of the primary benefits is the refinement of skin texture. By optimizing cell regeneration, the treatment smooths out rough patches and helps the skin regain a “polished” look often associated with the popular “glass skin” trend.
Salmon DNA Injection for Fine Lines and Elasticity
As a bio-stimulator, Salmon DNA increases dermal thickness. Scientific studies indicate that PDRN can increase collagen I synthesis by approximately 1.36-fold, effectively softening fine lines around the eyes and mouth while restoring a youthful bounce to the skin.
Salmon DNA Injection for Skin Repair and Hydration
Because Salmon DNA has strong water-binding properties, it deeply hydrates the skin. It is also an excellent treatment for acne scars, as it promotes tissue remodeling in depressed or pitted areas.
Results Timeline
| Timeline | Expected Results |
| Week 1 | Improved hydration and a noticeable “glow” as inflammation subsides. |
| Month 1 | Visible reduction in pore size and smoother skin texture. |
| Month 3+ | Peak collagen production; skin feels firmer and fine lines are softened. |
Results After 1 Week
Within the first seven days, the initial “injection bumps” disappear, leaving the skin looking more hydrated and rested.
After 1 Month
By the one-month mark, the skin’s internal repair process is in full swing. Patients often report that their skin feels more resilient and that makeup applies more smoothly.
Long-Term Results
The long-term effects focus on skin health. Results typically last 6 to 12 months, though maintenance sessions are recommended to keep the regenerative cycle active.
Salmon DNA Injection Procedure Explained
How Salmon DNA Injection Is Performed
The procedure involves a series of micro-injections into the superficial dermis. Most practitioners apply a topical numbing cream for 20–30 minutes beforehand to ensure a comfortable experience.
How Many Sessions Are Typically Required?
For optimal results, a “loading dose” of 3 to 4 sessions, spaced 2 to 4 weeks apart, is generally recommended. This allows the skin to build up a significant reserve of regenerative materials.
Salmon DNA Injection Side Effects
Common Side Effects
The most common side effect is small, hive-like bumps at the injection sites. These are simply the viscous DNA gel sitting in the skin and usually resolve within 24 to 48 hours.
Less Common and Rare Side Effects
Bruising: Occasional mild bruising may occur at the injection points.
Redness: A slight pinkish tint to the skin for the first day.
Allergic Reactions: Rare, but possible in individuals with severe seafood allergies.
Salmon DNA Injection vs Other Skin Treatments
Vs. Skin Boosters: While HA boosters provide instant “plumping” through hydration, Salmon DNA focuses on biological repair and long-term tissue health.
Vs. Laser Treatments: Lasers use heat to resurface the skin; Salmon DNA uses biocompatible fragments to heal it. In 2026, many clinics combine both for enhanced results.
FAQs
1. Is Salmon DNA injection safe?
Yes, Salmon DNA is highly bio-compatible with human DNA and is naturally broken down and absorbed by the body, making it one of the safest regenerative treatments available.
2. How long do Salmon DNA injection results last?
Initial results from a full course last about 6–12 months. Periodic maintenance sessions every 6 months can extend these benefits indefinitely.
3. Does Salmon DNA injection look natural?
Absolutely. Because it does not add volume or freeze muscles, it only improves the quality and health of your own skin without changing your facial structure.
4. Who should avoid this treatment?
It is generally not recommended for pregnant women, individuals with uncontrolled diabetes, or those with known severe seafood allergies.
5. Is the treatment painful?
With numbing cream, most patients feel only a slight “stinging” sensation during the injection process.
Dr’s Note On This Treatment
“Instead of just ‘painting’ the surface with hydration, I tell my patients at Her Clinic Malaysia that Rejuran is about rebuilding the foundation. It’s a biological repair, not an instant cosmetic fix.
We’re using those salmon DNA fragments to actually signal your skin to heal itself, thicken the barrier, and quiet down that chronic inflammation we see so much in our tropical climate. You won’t see a new face overnight, but after three sessions, you’ll see skin that finally knows how to hold its own glow.”
— Dr. Jeff Khor, LCP-Certified Physician, Her Clinic Malaysia
Summary
Salmon DNA injections represent the future of “age-well” skincare. By focusing on repair rather than just masking symptoms, this treatment provides a foundation for healthy, radiant skin. Whether you are battling acne scars, enlarged pores, or early signs of aging, PDRN therapy offers a scientifically-backed path to rejuvenation.
