Introduction

South Korea is internationally recognized for its cutting-edge cosmetic dermatology treatments, offering innovative procedures that improve skin quality, reduce signs of aging, and stimulate natural regeneration. Two of the most popular injectable treatments among local and international patients are Sculptra and Rejuran. Although both promote healthier, younger-looking skin, they work through completely different mechanisms and are recommended for different skin concerns.

If you are planning a skin treatment in Korea, understanding the differences between Sculptra and Rejuran can help you choose the procedure that best matches your aesthetic goals. Sculptra is a collagen biostimulator designed to restore facial volume and improve skin firmness over time, while Rejuran is a polynucleotide-based skin healer that repairs damaged skin, improves elasticity, and enhances overall skin quality.

This guide compares Sculptra and Rejuran, explains how each treatment works, discusses their benefits, treatment areas, recovery, costs, expected results, and helps international patients determine which skin rejuvenation treatment is the right choice.

What Is Sculptra?

Sculptra is a collagen biostimulator made from:

• Poly-L-lactic acid (PLLA)

Unlike traditional dermal fillers, Sculptra gradually stimulates the body's natural collagen production.

It is commonly used to improve:

• Facial volume loss
• Skin laxity
• Hollow cheeks
• Deep facial folds
• Temples
• Overall facial rejuvenation

Results develop gradually over several months and provide long-lasting improvement.

What Is Rejuran?

Rejuran is a regenerative skin treatment made from purified polynucleotides (PN) derived from salmon DNA.

Rather than adding volume, Rejuran repairs damaged skin by stimulating tissue regeneration and improving the skin's natural healing process.

Rejuran is commonly used to improve:

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

It is widely used throughout Korea for natural skin rejuvenation.

How Sculptra Works

After injection, Sculptra stimulates fibroblasts to produce new collagen.

Over time, collagen restores:

• Facial volume
• Skin firmness
• Elasticity
• Facial contours

Because collagen develops naturally, improvements appear gradually.

How Rejuran Works

Rejuran delivers purified polynucleotides beneath the skin.

These polynucleotides stimulate:

• Skin repair
• Tissue regeneration
• Collagen production
• Improved elasticity
• Better hydration
• Healthier skin

Unlike Sculptra, Rejuran focuses primarily on skin healing rather than facial volume restoration.

Sculptra vs Rejuran: Key Differences

Primary Treatment Goal

Sculptra focuses on restoring facial volume through collagen stimulation.

Rejuran focuses on repairing damaged skin and improving overall skin quality.

Treatment Material

Sculptra contains:

• Poly-L-lactic acid (PLLA)

Rejuran contains:

• Polynucleotides (PN)

Facial Volume

Sculptra restores facial volume.

Rejuran provides little or no additional facial volume.

Skin Repair

Sculptra primarily stimulates collagen.

Rejuran actively repairs damaged skin and improves tissue regeneration.

Common Treatment Areas

Full Face

Both treatments are commonly used for overall facial rejuvenation.

Cheeks

Sculptra restores volume.

Rejuran improves skin quality.

Under-Eye Area

Rejuran is frequently used for delicate under-eye skin.

Sculptra is generally not injected directly into thin under-eye skin.

Acne Scar Areas

Rejuran is widely used for acne scar treatment.

Sculptra may improve skin firmness but is not considered a primary acne scar treatment.

Neck

Both treatments may improve skin quality.

Rejuran is commonly selected for neck rejuvenation.

Benefits of Sculptra

Potential benefits include:

• Long-term collagen stimulation
• Natural facial volume restoration
• Improved skin firmness
• Better facial contours
• Gradual rejuvenation
• Long-lasting results

Benefits of Rejuran

Potential benefits include:

• Skin regeneration
• Tissue repair
• Better elasticity
• Improved hydration
• Reduced inflammation
• Healthier skin texture

Which Treatment Looks More Natural?

Both treatments produce natural-looking improvements because they stimulate the body's own regenerative processes.

Natural results depend on:

• Physician expertise
• Individual anatomy
• Proper treatment planning
• Personalized care

Which Treatment Is Better for Skin Quality?

Rejuran is generally preferred for improving:

• Skin texture
• Skin hydration

Sculptra focuses more on restoring facial structure.

Which Treatment Is Better for Facial Volume Loss?

Sculptra is the preferred choice for patients experiencing:

• Hollow cheeks
• Volume loss
• Facial aging
• Deep folds

Rejuran does not significantly restore facial volume.

Treatment Process

Initial Consultation

Before treatment, your physician reviews:

• Medical history

• Previous cosmetic procedures
• Allergies
• Skin concerns
• Cosmetic goals

Skin Assessment

Your dermatologist evaluates:

• Skin elasticity
• Facial volume
• Wrinkles
• Acne scars
• Skin quality
• Overall facial anatomy

This assessment determines whether Sculptra or Rejuran is more appropriate.

Injection Procedure

Both procedures are outpatient treatments using multiple fine injections.

Treatment duration depends on:

• Treatment area
• Individual treatment plan
• Physician technique

Recovery After Treatment

Most patients return to normal activities shortly after treatment.

Temporary side effects may include:

• Mild swelling
• Redness
• Bruising
• Tenderness

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

How Long Do Results Last?

Treatment longevity depends on:

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

Both treatments typically require maintenance sessions for continued improvement.

Can Sculptra and Rejuran Be Combined?

Yes.

Many Korean dermatologists combine both procedures.

For example:

• Sculptra restores facial volume.
• Rejuran improves skin quality and tissue repair.
• Together they provide comprehensive facial rejuvenation.

Combination treatment should always be planned by an experienced dermatologist.
