Salmon DNA Injections: Benefits, Cost, and Safety Facts in Malaysia

Salmon DNA, also called PDRN (Polydeoxyribonucleotide), is a purified DNA fragment extracted from salmon sperm. It’s used in injectable skin treatments to repair damaged tissue and boost collagen. Popular in Korea as “Rejuran,” salmon DNA injections help improve skin hydration, elasticity, and acne scars by stimulating cell regeneration and reducing inflammation.

The phrase “salmon sperm facial” or “salmon DNA injection” might sound bizarre, but behind the internet trend lies solid clinical science. Known in the medical field as PDRN or PN therapy, salmon DNA injections represent one of the fastest-growing sectors of regenerative aesthetic medicine.

Unlike traditional treatments that mask cosmetic concerns, these biological molecules work at a cellular level to rebuild damaged tissue, repair skin barriers, and revitalize dormant hair follicles.

What Salmon DNA Injections Actually Do

How PDRN Works in Skin Cells

To understand how salmon DNA works, we look at two specific biomolecules: Polydeoxyribonucleotide (PDRN) and Polynucleotide (PN). These are long-chain nucleotide blocks extracted from the germ cells of salmon trout, which are then ultra-purified to remove all active proteins and lipids, leaving zero fishy traits behind.

When injected directly into the dermis (the middle layer of skin), these molecules bind to A2A adenosine receptors. This binding action kicks off two primary healing processes:

1. The Nucleotide Salvage Pathway: Cells require immense energy to duplicate DNA during repair. PDRN supplies ready-made nucleotide building blocks, allowing tired or damaged cells to bypass slow synthesis and fast-track their own healing.

2. Neovascularization (Angiogenesis): PDRN triggers the expression of Vascular Endothelial Growth Factor (VEGF), which prompts the body to weave a tight web of new micro-capillaries. This floods the treated area with fresh oxygen and nutrients.

Salmon DNA vs Rejuran Treatment

While people often use the terms interchangeably, Rejuran Healer is a specific, commercial brand of injectable skin booster made of PN, whereas PDRN is the broader pharmaceutical-grade raw material used in wound healing gels and alternative scalp shots.

FDA and Global Approval Status

The legal status of salmon DNA injections varies significantly by region:

• South Korea (KFDA) & Asia: Fully approved and considered a gold standard, baseline aesthetic treatment alongside basic skin boosters.

• Europe (CE Mark): PDRN and PN compounds are broadly approved as Class III medical devices for skin rejuvenation and wound management (e.g., Plinest).

• United States (FDA): As of 2026, the FDA has not officially approved Rejuran or PDRN injections specifically for cosmetic facial use. However, board-certified dermatologists and plastic surgeons frequently import these approved formulations to administer them off-label, or utilize topical PDRN paired with microneedling.

Key Benefits People Get From Salmon DNA Injections

Skin Rejuvenation and Hydration Effects

Salmon DNA works differently than topical serums. By stimulating fibroblasts, it increases the synthesis of type I and type III collagen alongside natural elastin. This restores a dense, bouncy texture to thinning or crepey skin.

While it is not a direct volume filler, its capacity to lock in endogenous water molecules transforms dry skin into a radiant, “glass-skin” texture from the inside out.

Acne Scars and Texture Improvement

For uneven skin texture and atrophic acne scars, clinics utilize a dense formulation called Rejuran S.

When injected precisely beneath depressed scar tissues, the polynucleotides break up fibrous bands while forcing fibroblasts to generate clean, unscarred dermal scaffolding. This reduces scar depth and shrinks enlarged pores far more effectively than standard chemical peels.

Hair Growth and Scalp Applications

The scalp is an extension of our skin, and salmon DNA is quickly becoming a premier treatment for thinning hair (including early-stage Androgenetic Alopecia and postpartum shedding).

Clinical trials highlight that micro-injecting PDRN into the scalp blocks chronic inflammation and guards the delicate hair matrix against DHT (dihydrotestosterone)-mediated follicle death.

Clinical Data Point: A landmark trial published in the Archives of Dermatological Research demonstrated an 82.1% patient improvement rate in hair density and diameter following a 4-session polynucleotide injection protocol. When paired with microneedling, studies showcase hair thickness improvements reaching up to 53.1%.

Salmon DNA Treatment Cost, Procedure, and What to Expect

Price Per Session in Malaysia

Because it requires premium, ultra-purified raw biomaterials, salmon DNA treatments are valued as a premium cosmetic medical procedure.

Treatment Timeline and Downtime

A standard corrective protocol requires 3 to 4 sessions spaced 3 to 4 weeks apart. Peak collagen restructuring and the notable “lit-from-within glow” typically show up 4 weeks after your second session.

Downtime is brief but visible: because the thick gel is placed superficially, you will exit the clinic with small, raised papules (resembling symmetric mosquito bites) across the injection sites. These naturally dissipate within 24 to 48 hours as your skin absorbs the product.

Pain Level and Aftercare Steps

Let’s be candid: manual micro-injections can be quite pinpricky and uncomfortable. To manage this, providers apply a high-strength topical numbing cream (lidocaine) for 45 minutes prior to the procedure.

Post-Treatment Protocol

Side Effects and Who Should Avoid It

Common Reactions After Treatment

The overwhelming majority of reactions are mechanical results of the needle itself, rather than the salmon DNA compound. Expect mild localized redness, occasional bruising, tenderness, and transient swelling. These side effects are mild and resolve completely within 2 to 5 days.

Medical Conditions That Increase Risk

While salmon DNA boasts a 99.9% structural match to human cells, certain individuals should completely avoid the treatment:

• Severe Seafood/Fish Allergies: While the intensive purification process strips out almost all fish proteins, individuals prone to anaphylactic seafood reactions must avoid it out of caution.

• Blood Disorders: Anyone taking high-dose blood thinners or dealing with bleeding disorders will face excessive bruising.

• Active Localized Infections: Injections should never be performed through active cystic acne flare-ups, open cold sores, or eczema patches.

• Pregnancy and Breastfeeding: Due to a lack of clinical safety profiles on pregnant or lactating individuals, ethical guidelines mandate postponing the treatment.

FAQ

How long do salmon DNA results last?

After completing an initial 3-to-4 session starter cycle, structural improvements in elasticity and skin barrier health typically last for 6 to 12 months. To keep those results fresh, dermatologists recommend a single maintenance session every 6 months.

Are salmon DNA injections better than fillers?

They are not “better”—they simply serve entirely different purposes. Dermal fillers use hyaluronic acid to physically plump up deep volume loss, like hollow cheeks or flat lips. Salmon DNA does not add fake volume; it improves the actual texture, density, and thickness of the skin fabric itself. They are frequently paired together for comprehensive facial rejuvenation.

Can I get salmon DNA injections at home?

Absolutely not. Injecting anything into the facial dermis requires absolute sterility, expert anatomical knowledge of facial vessels to avoid vascular occlusions, and medical certification. At-home attempts via unverified internet syringes carry high risks of severe infection, scarring, and permanent tissue necrosis. However, you can safely use low-molecular-weight topical PDRN serums at home as part of your standard skincare routine.
