Introduction

South Korea has become one of the world's leading destinations for advanced aesthetic dermatology, attracting thousands of international patients seeking minimally invasive skin rejuvenation procedures. Among the most popular injectable treatments are Radiesse and Rejuran. Although both improve skin appearance and promote youthful-looking results, they work very differently and are designed to treat different cosmetic concerns.

For international patients visiting Korea, understanding these differences is essential when planning cosmetic procedures during a limited travel schedule. Radiesse is primarily a collagen-stimulating injectable that restores facial volume and improves skin firmness, while Rejuran is a regenerative polynucleotide treatment that focuses on repairing damaged skin, improving elasticity, and enhancing overall skin health.

This guide compares Radiesse and Rejuran, explains how each treatment works, discusses treatment areas, recovery, costs, long-term benefits, and helps international patients determine which injectable treatment is best suited to their aesthetic goals.

What Is Radiesse?

Radiesse is a collagen-stimulating injectable composed of:

• Calcium hydroxylapatite (CaHA) microspheres
• Gel carrier

The gel immediately restores facial volume while calcium hydroxylapatite stimulates the body's natural collagen production over time.

Radiesse is commonly used for:

• Facial volume restoration
• Jawline contouring
• Chin enhancement
• Cheek augmentation
• Nasolabial folds
• Hand rejuvenation

It combines immediate correction with gradual collagen regeneration.

What Is Rejuran?

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

Rather than restoring facial volume, Rejuran stimulates skin healing and regeneration.

It is commonly used to improve:

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

Rejuran has become one of Korea's signature skin rejuvenation treatments.

How Radiesse Works

Radiesse provides immediate structural support through its gel carrier.

The calcium hydroxylapatite particles gradually stimulate collagen production, improving:

• Facial firmness
• Skin support
• Elasticity
• Long-term facial contours

How Rejuran Works

Rejuran delivers polynucleotides beneath the skin.

These molecules stimulate:

• Tissue repair
• Cellular regeneration
• Improved skin elasticity
• Better hydration
• Healthier skin

Unlike Radiesse, Rejuran focuses on skin healing rather than facial contour enhancement.

Radiesse vs Rejuran: Key Differences

Primary Treatment Goal

Radiesse focuses on:

• Facial volume
• Structural support
• Collagen stimulation

Rejuran focuses on:

• Skin repair
• Regeneration
• Skin quality improvement

Treatment Material

Radiesse contains:

• Calcium hydroxylapatite (CaHA)

Rejuran contains:

• Polynucleotides (PN)

Facial Volume

Radiesse restores facial volume immediately.

Rejuran provides little or no additional facial volume.

Skin Repair

Rejuran actively repairs damaged skin.

Radiesse primarily stimulates collagen production.

Common Treatment Areas

Cheeks

Radiesse restores volume.

Rejuran improves skin quality.

Jawline

Radiesse is commonly used for contouring.

Rejuran is not typically used for structural enhancement.

Under-Eye Area

Radiesse is generally avoided in this area.

Acne Scar Areas

Rejuran is widely used for acne scar improvement.

Radiesse is not considered a primary acne scar treatment.

Neck

Rejuran is commonly used for neck rejuvenation.

Benefits of Radiesse

Potential benefits include:

Benefits of Rejuran

Potential benefits include:

• Skin regeneration
• Improved elasticity
• Better hydration
• Skin repair
• Reduced fine lines
• Improved skin texture

Which Treatment Looks More Natural?

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

Natural results depend on:

• Physician expertise

Skin Assessment

Your dermatologist evaluates:

• Skin quality
• Facial volume
• Elasticity
• Wrinkles
• Acne scars
• Facial anatomy

This determines whether Radiesse or Rejuran is more appropriate.

Injection Procedure

Both treatments are outpatient procedures performed using multiple fine injections.

Treatment duration depends on:

• Number of syringes
• Individual treatment plan

Recovery After Treatment

Most patients resume normal activities shortly after treatment.

Temporary side effects may include:

How Long Do Results Last?

Treatment longevity depends on:

• Skin condition
• Lifestyle
• Number of treatment sessions

Both treatments usually require maintenance sessions for continued improvement.

Can Radiesse and Rejuran Be Combined?

Yes.

Many Korean dermatologists combine both procedures.

For example:

• Radiesse restores facial contours.
• Rejuran repairs and regenerates skin.
• Together they provide comprehensive facial rejuvenation.

Combination treatment should always be customized by an experienced dermatologist.
