Introduction

South Korea has become one of the world's leading destinations for regenerative skin treatments, offering innovative injectable procedures that improve skin health without surgery. Among the most talked-about polynucleotide (PN) treatments are Rejuran and Nucleofill. Both are designed to stimulate the skin's natural repair process, improve skin quality, and promote long-term rejuvenation, but they differ in formulation, treatment goals, and ideal patient profiles.

If you're planning a dermatology treatment in Korea, understanding the differences between Rejuran and Nucleofill can help you choose the option that best matches your skin concerns. While Rejuran is widely recognized for repairing damaged skin and improving acne scars, Nucleofill focuses on deep tissue regeneration, hydration, and antioxidant protection. Both treatments deliver natural-looking improvements but are recommended for different skin conditions.

This guide compares Rejuran and Nucleofill, explains how each treatment works, discusses their benefits, treatment areas, recovery, costs, expected results, and helps international patients determine which polynucleotide treatment is most suitable.

What Is Rejuran?

Rejuran is a regenerative injectable treatment formulated with highly purified polynucleotides (PN) derived from salmon DNA.

Rather than adding facial volume, Rejuran encourages the skin's natural healing and regeneration processes.

It is commonly used to improve:

• Skin texture
• Fine lines
• Skin elasticity
• Acne scars
• Skin barrier function
• Overall skin quality

Rejuran is widely used in Korean dermatology clinics as a skin-healing treatment.

What Is Nucleofill?

Nucleofill is another polynucleotide-based injectable treatment designed to regenerate skin and improve tissue quality.

Its formulation supports:

• Skin regeneration
• Deep hydration
• Antioxidant protection
• Fibroblast stimulation
• Skin elasticity
• Overall skin rejuvenation

Unlike traditional fillers, Nucleofill focuses on improving skin health rather than creating volume.

How Rejuran Works

Rejuran supports natural skin repair by stimulating regenerative activity within the skin.

Treatment may improve:

• Skin healing
• Skin elasticity
• Skin texture
• Fine wrinkles
• Acne scars
• Overall skin quality

Results appear gradually as the skin renews itself.

How Nucleofill Works

Nucleofill promotes skin regeneration while supporting hydration and protecting cells from oxidative stress.

Treatment may improve:

• Skin elasticity
• Moisture retention
• Skin firmness
• Tissue regeneration
• Skin quality
• Overall skin appearance

Results also develop gradually over time.

Rejuran vs Nucleofill: Key Differences

Primary Treatment Goal

Rejuran focuses on repairing damaged skin and supporting long-term regeneration.

Nucleofill combines regenerative effects with enhanced hydration and antioxidant activity.

Skin Hydration

Rejuran improves hydration indirectly through healthier skin.

Nucleofill places greater emphasis on improving deep skin hydration.

Antioxidant Support

Rejuran primarily supports tissue repair.

Nucleofill also provides antioxidant benefits that may help protect skin cells from environmental damage.

Skin Improvement

Both treatments improve:

• Skin texture
• Elasticity
• Fine lines
• Overall skin quality

However, they achieve these improvements through slightly different biological pathways.

Common Treatment Areas

Full Face

Both treatments are widely used for complete facial rejuvenation.

Under-Eye Area

Both may improve delicate under-eye skin depending on physician assessment.

Cheeks

Both treatments improve:

• Skin texture
• Fine wrinkles
• Elasticity
• Overall skin quality

Forehead

Both procedures may improve skin smoothness and elasticity.

Neck

Both treatments are commonly used for neck rejuvenation.

Hands

Some physicians also use polynucleotide treatments for improving skin quality on the hands.

Benefits of Rejuran

Potential benefits include:

• Skin regeneration
• Improved elasticity
• Better texture
• Acne scar improvement
• Fine wrinkle reduction
• Stronger skin barrier

Benefits of Nucleofill

Potential benefits include:

• Deep skin hydration
• Improved elasticity
• Tissue regeneration
• Antioxidant protection
• Better skin firmness
• Healthier skin quality

Which Treatment Looks More Natural?

Both Rejuran and Nucleofill provide subtle, natural-looking improvements because they enhance skin quality instead of altering facial contours.

Natural results depend on:

• Proper skin assessment
• Physician experience
• Individual treatment planning
• Correct injection technique

Which Treatment Is Better for Dry Skin?

Nucleofill is often recommended when hydration is the primary concern.

Rejuran also improves skin hydration indirectly by strengthening overall skin health.

Which Treatment Is Better for Acne Scars?

Rejuran is frequently recommended for acne scar improvement due to its regenerative properties.

Nucleofill may improve overall skin quality but is generally selected for hydration and tissue support rather than scar-focused treatment.

Treatment Process

Initial Consultation

Before treatment, your physician reviews:

• Medical history
• Current medications
• Previous cosmetic procedures
• Allergies
• Skin concerns
• Cosmetic goals

Skin Assessment

Your dermatologist evaluates:

• Skin hydration
• Elasticity
• Texture
• Fine wrinkles
• Acne scars
• Overall skin quality

This assessment determines whether Rejuran or Nucleofill is more appropriate.

Injection Procedure

Both treatments are performed during outpatient appointments using multiple fine injections.

Treatment time varies depending on the treatment area and individualized treatment plan.

Recovery After Treatment

Most patients return to normal activities shortly after treatment.

Temporary side effects may include:

• Mild swelling
• Redness
• Bruising
• Tenderness
• Injection marks

Following aftercare instructions supports proper healing.

Cost Comparison in Korea

Treatment costs depend on:

• Product selected
• Number of sessions
• Treatment area
• Physician experience
• Clinic location

Your dermatologist will recommend treatment according to your skin condition rather than price alone.

How Long Do Results Last?

Treatment longevity depends on:

• Skin condition
• Lifestyle
• Number of treatment sessions
• Natural aging process

Both Rejuran and Nucleofill usually require multiple sessions followed by maintenance treatments for optimal long-term results.

Can Rejuran and Nucleofill Be Combined?

In selected patients, combination treatment may be appropriate.

For example:

• Rejuran may improve skin regeneration.
• Nucleofill may enhance hydration and tissue support.
• Together they may provide comprehensive skin rejuvenation.

Combination treatment should always be planned by an experienced dermatologist.

Why International Patients Choose Korea

Many international patients choose Korea because of:

• Experienced cosmetic dermatologists
• Advanced regenerative skin treatments
• Personalized treatment planning
• Modern dermatology clinics
• Access to the latest polynucleotide technologies

The experience of the physician is generally more important than selecting a specific injectable product.
