Quick answer: In Rejuran vs PRP for skin texture, both support skin repair, but they come from different sources. Rejuran is a ready-made polynucleotide (PN) booster that gives fairly consistent results for pores, fine lines and scars. PRP uses growth factors from your own blood, so results vary more between people. Many doctors find Rejuran more predictable for texture.
Key takeaways
- Rejuran uses PN from salmon DNA; PRP uses platelets from your own blood.
- Both aim to support repair, collagen and smoother skin.
- Rejuran is a standard product; PRP quality depends on your blood and the preparation method.
- PRP needs a blood draw on the day of treatment.
- Both usually need a series of sessions.
What is Rejuran?
Rejuran is a skin booster made by PharmaResearch in Korea and approved by the Ministry of Food and Drug Safety. It contains polynucleotides (PN), DNA fragments from salmon. Small injections across the face support skin repair and elasticity, which can improve fine lines, pores, redness and early acne scars. Rejuran S is a version made for scars.
What is PRP?
PRP stands for platelet-rich plasma. A small amount of your blood is drawn and spun in a centrifuge to separate the platelets, which contain growth factors. The concentrated plasma is then injected into the skin or applied after microneedling. The growth factors are thought to support healing and collagen. Because it comes from your own body, allergy risk is very low.
How do Rejuran and PRP compare?
- Source: Rejuran is a manufactured PN product; PRP comes from your own blood.
- Consistency: Rejuran is standardised; PRP varies by person and preparation.
- Best for: Rejuran for pores, fine lines, sensitivity and scars; PRP for general rejuvenation and as an add-on to microneedling.
- Sessions: both often 2 to 4 sessions a few weeks apart.
- Downtime: Rejuran small bumps for a day or two; PRP redness, swelling or bruising for one to three days.
- Allergy: PRP very low risk; Rejuran needs care with fish allergy.
Which is better for pores and fine lines?
Rejuran is often preferred for enlarged pores, fine lines and thin, tired skin. Its effects are well documented in Korea, and because the product is the same each time, results tend to be more predictable. Many people notice smoother, brighter skin after two or three sessions.
Which is better for acne scars?
Both can help. Rejuran S is designed for scars, and PRP is often combined with microneedling or fractional lasers to support healing. For deeper scars, doctors usually combine boosters with lasers or subcision rather than relying on one injection alone.
Who might prefer PRP?
PRP may suit people who prefer a treatment made from their own body or who have allergies to other products. It is also used in hair loss treatment. However, its results can vary more, and it needs a blood draw and preparation time on the day.
Can you combine them?
Yes. Some doctors combine PN boosters with PRP, or use one alongside lasers and microneedling. The best plan depends on your skin concern, schedule and comfort with injections.
What is the downtime?
After Rejuran, small bumps appear and usually settle within a day or two. After PRP, the skin may look red and slightly swollen for one to three days, especially when combined with microneedling. Bruising is possible with both.
Is it safe?
Both are safe when done by trained doctors in a clean setting. Possible side effects include redness, swelling, bruising and rarely infection. Tell your doctor about fish allergies before Rejuran and about blood disorders or blood thinners before PRP.
How to choose
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Texture and pore treatments are a major reason visitors come. If you want predictable results, Rejuran is often recommended; PRP is an option if you prefer an autologous treatment.
