Rejuran Treatment Korea – Salmon DNA Skin Booster
Rejuran is one of Korea’s most well-known skin booster treatments, often referred to as a “salmon DNA injection” due to its polynucleotide (PN) content derived from salmon DNA. It is designed to repair and regenerate the skin at a cellular level.
Below is a clinic-style guide to Rejuran treatment in Korea — how it works, what it does, and how sessions are typically performed.
1. What Rejuran Does
Rejuran contains polynucleotides (PN/PDRN) that promote skin regeneration:
- Repairs damaged skin tissue
- Stimulates collagen production
- Improves elasticity and firmness
- Strengthens the skin barrier
It focuses on improving skin quality rather than adding volume.
2. Common Treatment Areas
Rejuran is typically injected into:
- Full face
- Under-eye area
- Neck
- Acne scars or localized problem areas
Different formulations may be used depending on the area.
3. Injection Method
- Microinjections delivered evenly across the skin
- Injected into the dermis or superficial subdermal layer
- Fine needles or cannula may be used
This allows uniform distribution for overall skin improvement.
4. Typical Treatment Plan
Session Plan (Korea)
- Initial course:
→ 3–4 sessions - Interval:
→ Every 3–4 weeks - Maintenance:
→ Every 3–6 months
Results improve progressively with each session.
5. What to Expect After Treatment
- Immediate: small bumps, redness, mild swelling
- 1–3 days: bumps gradually subside
- 1–2 weeks: improved hydration and texture
- 3–6 weeks: increased elasticity and smoother skin
Downtime is short but visible for a few days due to injections.
6. Who is a Good Candidate
- Aging or thinning skin
- Rough texture or enlarged pores
- Sensitive or damaged skin
- Patients seeking natural skin regeneration
It is suitable for those who want gradual, long-term improvement.
7. Why Rejuran is Popular in Korea
- Strong focus on skin regeneration
- Natural-looking results without volume change
- Compatible with lasers and other treatments
- Widely used in maintenance-based skincare routines
It aligns with Korea’s preference for healthy, resilient skin.
Summary
Rejuran treatment in Korea typically includes:
- PN (salmon DNA)-based skin regeneration
- 3–4 initial sessions spaced 3–4 weeks apart
- Gradual improvement in texture and elasticity
- Short downtime with visible injection marks
- Maintenance treatments every few months
This makes it a leading option for improving overall skin quality from within.
