Rejuran Healer is one of Korea’s most popular injectable skin treatments, designed to repair, regenerate, and strengthen the skin from within.
Unlike fillers or typical skin boosters, it uses polynucleotides (salmon DNA) to improve skin quality at a cellular level, making it a top choice for natural anti-aging and skin recovery.

What Is Rejuran Healer?

Rejuran Healer is an injectable treatment that delivers polynucleotides (PN)—highly purified DNA fragments derived from salmon—into the skin.

👉 These PN molecules are highly compatible with human skin and work by:

• Stimulating skin repair
• Promoting collagen production
• Reducing inflammation

👉 In Korea, it’s often called the “skin healer injection” because it focuses on regeneration, not just cosmetic enhancement.

How Rejuran Works (Key Mechanism)

Once injected into the dermis, Rejuran:

• Activates fibroblasts (cells that produce collagen)
• Repairs damaged skin tissue
• Improves elasticity and moisture balance
• Strengthens the skin barrier

👉 Clinical studies show polynucleotides can improve skin texture, elasticity, and scar appearance.

👉 It works differently from HA boosters:

• HA = hydration
• Rejuran = repair + regeneration

What Does Rejuran Improve?

Best for:

• Acne scars
• Enlarged pores
• Fine lines and wrinkles
• Dull or damaged skin
• Thin or sensitive skin
• Redness and inflammation

👉 It’s especially effective for skin that needs healing, not just hydration.

What Makes Rejuran Unique?

1. True Skin Regeneration (Not Just Hydration)

Rejuran improves the structure of the skin, not just the surface.

2. Natural-Looking Results

• No volume added
• No change in facial shape

👉 Results look like better skin—not “done” skin

3. Long-Term Improvement

• Gradual collagen remodeling
• Strengthens skin over time

👉 Effects build over weeks rather than instantly.

Treatment Areas

Rejuran can be used on:

• Full face
• Under-eye area (very popular in Korea)
• Neck
• Acne scar areas

👉 Under-eye Rejuran is especially common for:

• Dark circles
• Fine wrinkles

What Is the Procedure Like?

Procedure

• Duration: 20–40 minutes
• Method: multiple micro-injections
• Numbing cream applied

Pain Level

• Moderate (more than typical skin boosters)

👉 Many clinics use advanced injection techniques to reduce discomfort.

Downtime & Recovery

Immediately After

• Small bumps (injection points)
• Redness
• Mild swelling

👉 Usually resolves within:

• 1–3 days

Short-Term Effects

• Slight bruising
• Mild sensitivity

👉 Most patients return to normal activities quickly.

When Will You See Results?

• 1–2 weeks: improved hydration and texture
• 3–4 weeks: smoother skin
• 1–3 months: collagen regeneration

👉 Results are gradual but long-lasting

How Many Sessions Are Needed?

Typical protocol:

• 3–4 sessions
• Spaced 3–4 weeks apart

👉 Maintenance every ~6 months is common for sustained results.

How Long Do Results Last?

• ₩300,000 – ₩800,000 per session

👉 Price varies depending on:

• Area treated
• Product type (Healer, i, S, etc.)
• Clinic expertise

Is Rejuran Safe?

Yes—With Proper Medical Use

• Made from biocompatible DNA fragments
• Low risk of allergic reaction

👉 Widely used in Korea and supported by clinical research as a safe and effective regenerative treatment.

Possible Side Effects

• Redness
• Swelling
• Bruising

👉 These are usually mild and temporary.

Rejuran vs Other Skin Boosters

• Rejuran → repair + regeneration
• HA boosters (e.g., Juvelook) → hydration + glow

👉 Many Korean clinics combine both for:

• Faster results
• Better long-term skin quality

Who Is a Good Candidate?

You are a good candidate if you:

• Have damaged or sensitive skin
• Want natural anti-aging
• Have acne scars or enlarged pores
• Prefer subtle, long-term improvement

👉 Not ideal if you want:

• Instant volume
• Dramatic lifting

Korean Dermatology Approach (Key Insight)

In Korea, Rejuran is rarely used alone.

Common Combinations

• Rejuran + laser treatments
• Rejuran + skin boosters
• Rejuran + RF microneedling

👉 This enhances:

• Skin repair
• Collagen production
• Overall glow

Common Mistakes to Avoid

• Expecting instant results
• Doing only one session
• Choosing based on price alone
• Ignoring combination treatments

👉 Rejuran is a process—not a one-time fix

Key Takeaway

👉 Rejuran is not a filler—it’s a skin regeneration treatment

• Repairs
• Strengthens
• Rebuilds
