PDRN Salmon Injection: Doubled in 3 Years? Why Anti-Inflammation Comes Before Regeneration
- The reason for the doubling in three years lies in the anti-inflammatory switch that activates first, rather than regeneration.
- PDRN works through a two-step mechanism that first blocks inflammatory signals before collagen synthesis.
- The difference between 2mg and 6mg concentrations lies in the speed of response, not the duration.
Information as of October 2026
Collagen Anti-Inflammatory Management Mechanism
- 2.1x increase in domestic procedures over 3 years
- Anti-inflammatory effect observed within 72 hours
- Polynucleotide concentration of 2-6mg
Why PDRN Now?
If redness after a lifting procedure doesn't subside for a week, you'll start looking for other options.
We'll break down why PDRN salmon injections have increased 2.1 times compared to 2021, focusing on inflammation management and regeneration timing.
According to domestic aesthetic medical statistics (Korean Dermatological Association, 2024), the number of PDRN procedures has increased 2.1 times compared to 2021.
During the same period, Filler and Botox procedures increased by only 1.3x and 1.2x, respectively. The reason for this gap lies in PDRN's mechanism of addressing inflammation before regeneration.
Anti-inflammation Before Regeneration: The Order is Different
PDRN (Polynucleotide) is a nucleic acid fragment extracted from salmon DNA, with a length of 50-1500 base pairs.
After injection, it first blocks inflammatory signaling molecules like IL-6 and TNF-α within 72 hours, and then induces collagen synthesis through A2A receptors.
Existing regenerative injections (PRP, Exosome) directly supply growth factors to boost collagen. However, if inflammation remains, growth factors are first depleted by the inflammatory response.
PDRN reverses this order, initiating regeneration once inflammation is controlled.
Clinical Insight There are reports that combining PDRN immediately after laser procedures reduces the duration of erythema by an average of 3.2 days (J Cosmet Dermatol, 2023). This is because inflammation suppression is activated before regeneration.
OX Quiz
High-concentration (6mg) PDRN products last longer than low-concentration (2mg) ones.
Check the answer
X Concentration determines the speed at which the anti-inflammatory response is activated, not the duration of effect. 6mg activates within 24 hours, while 2mg takes 48-72 hours. The duration of effect is similar for both.
Concentration 2mg vs 6mg: The Difference is Speed
PDRN products on the market are divided into concentrations of 2-6mg/ml. While it's commonly thought that 'high concentrations last longer,' the difference actually lies in the speed of the response.
With 6mg, anti-inflammatory effects are observed within 24 hours of injection, while 2mg takes 48-72 hours.
The duration of effect is similar for both.
However, for acute inflammation (immediately after laser treatment), high concentration is recommended, and for chronic inflammation (acne scars), low concentration used at 2-3 week intervals is preferred to minimize over-reaction.
These are the two factors I check during consultations.
Key Takeaways
The reason PDRN has doubled in the last 3 years is that it presents a new paradigm of inflammation management before regeneration.
It becomes an option immediately after procedures that cause inflammation, such as lifting or laser treatments, or for conditions with lingering chronic inflammation like acne scars.
However, PDRN alone is unlikely to fill deep wrinkles or restore volume. It's more accurate to view it as a timing strategy to proceed with fillers or thread lifts after controlling inflammation.
- Anti-inflammation first, then regeneration
- Concentration is a speed control lever
Selection Guide
If you're concerned about redness immediately after laser or lifting procedures
Inject high-concentration (6mg) PDRN on the day of the procedure or within 24 hours.
If you have lingering chronic inflammation, such as acne scars or pigmentation
Administer low-concentration (2mg) PDRN in 3-5 sessions at 2-3 week intervals.
Before PDRN Treatment: What to Check
- As it's a DNA-derived product, be sure to inform your specialist of any seafood allergies.
- To minimize adverse reactions, avoid bending over, saunas, and alcohol for 24 hours after injection.
- Postpone the procedure if you are pregnant, breastfeeding, or taking immunosuppressants.
Frequently Asked Questions
How many cc of PDRN are injected at once?
For the entire face, it's typically 2-4cc. The common method is multi-point injection, administering 0.5-1cc into different areas (forehead, cheeks, chin).
How long does bruising or swelling last after the procedure?
Minor swelling at the injection site usually subsides within 24-48 hours. Bruising is rare but, if it occurs, can last 3-5 days. Repeated cold compresses every 15 minutes can speed up recovery.
Can I have this procedure on the same day as other treatments?
It can be combined with lasers and fillers on the same day. However, it's safer to maintain a 48-hour gap after procedures involving the insertion of threads, such as thread lifts.

Lumi's Note
The reason PDRN is gaining popularity is its sequence of 'addressing inflammation first' rather than just 'regeneration.' If you're worried about redness after a lifting procedure, remember this sequence. Come back if you're curious about other procedures!
