Exosome vs. Salmon Injection vs. Skin Booster: How to Choose the Right One?

- Even though they're both regenerative injections, the PDRN content and duration of effect differ by three times.
- Exosomes facilitate cell signaling, salmon injections repair DNA, and Skin Boosters hydrate—their mechanisms of action are different.
- Based on a budget of 300,000 KRW, choices vary depending on the duration of effect and intended purpose.
Information as of October 2026
Comparing Ingredients, Duration, and Price
- Exosome average duration: 3-4 months
- PDRN regenerative power: 60% of Exosome
- Skin Booster per session: ₩150,000 - ₩250,000
Why Are the 3 Types of Regenerative Injections So Confusing?
Looking in the mirror, I suddenly searched for 'Exosome' on the search engine, and Salmon Injection and Skin Booster appeared alongside it.
Since all three talk about regenerative effects, you might think they're the same, but the cost difference is twofold, and the duration varies.
The key lies in the ingredient structure. Exosomes are nano-particles derived from stem cells, Salmon Injection is DNA fragments (PDRN), and Skin Booster is hyaluronic acid-based—they all start from different points.
This difference dictates the duration of effects and the price.
Differences in Action Based on Ingredients
Exosomes are 30-150nm vesicles secreted by cells.
They contain growth factors and proteins that signal skin cells to induce collagen synthesis (Korean Society for Dermatology, 2023). This regenerative signaling method allows the effects to spread widely.
Salmon Injection (PDRN) is polydeoxyribonucleotide extracted from salmon DNA.
It works through DNA repair pathways to directly restore damaged cells—it's strong for scars and inflammatory marks.
Skin Booster creates volume by filling the dermis with moisture using a hyaluronic acid + vitamin cocktail.
OX Quiz
Exosome treatments are always more effective than Salmon Injection.
Check the answer
X Exosomes excel at broad regeneration, while Salmon Injection is strong for localized scar and inflammation repair. The choice depends on the goal.
Where Do Duration and Cost Differ?

Exosomes last an average of 3-4 months per session, with costs ranging from ₩300,000 to ₩500,000.
Salmon Injection lasts 2-3 months for ₩200,000 - ₩350,000, and Skin Booster lasts 1-2 months for ₩150,000 - ₩250,000—shorter duration means lower price.
Be cautious, as some products with low PDRN content are sometimes labeled as Exosomes. Check the product's ingredient label (Exosome concentration in ppm/PDRN in mg) before treatment.
The hyaluronic acid concentration in Skin Boosters varies by brand, with differences of 10-20mg/ml.
Caution Some products labeled as Exosomes are mixed with PDRN. Check for pure Exosome content (above 10^9 particles/ml).
| Category | Exosome | Salmon Injection (PDRN) | Skin Booster |
|---|---|---|---|
| Main Ingredient | Stem cell-derived nano-particle | Salmon DNA fragment | Hyaluronic acid |
| Duration | 3-4 months | 2-3 months | 1-2 months |
| Cost per Session | ₩300,000 - ₩500,000 | ₩200,000 - ₩350,000 | ₩150,000 - ₩250,000 |
| Primary Target | Overall regeneration & elasticity | Scars & inflammatory marks | Dryness & dehydration |
Costs may vary depending on product brand, treatment area, and medical institution
Selection Criteria Based on Your Skin Concerns
If your budget is ₩300,000, you have to choose between one session of Exosome or two sessions of Skin Booster.
For short-term events (weddings, photoshoots), Skin Booster provides immediate radiance, while for long-term management, Exosomes are more efficient.
If your goal is localized regeneration for acne scars or surgical scars, Salmon Injection is the priority. For addressing pores, elasticity, and wrinkles simultaneously, Exosomes are better—the wider the scope, the more advantageous the signaling method.
- For lasting effects, choose Exosomes; for immediate radiance, choose Skin Booster
- PDRN is effective for scars and inflammatory marks
Situational Selection Guide
Budget under ₩300,000 + Need for immediate radiance
Two divided sessions of Skin Booster
Splitting treatments a week before and right before an event allows you to hit the peak timing.
Focused management for acne scars & surgical scars
Three sessions of Salmon Injection (PDRN) at 3-week intervals
The DNA repair pathway is strong for localized regeneration, and cumulative effects from 3 sessions show over 60% improvement in pigmentation.
Misconceptions
Myth Exosomes, Salmon Injection, and Skin Booster have different ingredients but similar effects.
Truth Their mechanisms of action differ. Exosomes use cell signaling, Salmon Injection uses DNA repair, and Skin Booster focuses on hydration—even within the 'regeneration' category, the target layers and duration differ by 2-3 times.
Pre-Treatment Checklist
- !!Check the Exosome purity (particles/ml) and PDRN content (mg) on the product label—do not mistake mixed types for pure Exosomes!!
- Avoid saunas and alcohol within 24 hours after Skin Booster treatment to prevent swelling from lasting 2-3 days longer.
- If you have a salmon allergy, a patch test is mandatory before PDRN treatment.
Frequently Asked Questions
Can I mix the three treatments?
It's possible, but the risk of swelling increases due to ingredient overlap (hyaluronic acid), so a 2-week interval is usually recommended.
How long does bruising last after Exosome treatment?
It's usually like needle marks, lasting 2-3 days, but can last up to 5 days in severe cases—cold compresses for 48 hours are essential.
Skin Booster is the cheapest, so why do people seek out Exosomes?
Skin Booster requires repetition every 1-2 months, leading to an annual cost of over ₩1,800,000—Exosomes cost around ₩1,200,000 per year.

Lumi's Note
All three injections use the word 'regeneration,' but they take different paths. Deciding what your skin needs right now—moisture, scar repair, or overall elasticity—makes the choice much easier. I hope the 3-axis criteria organized today become your list of questions during your clinic consultation.
