Rejuran vs Sculptra: Which Collagen Treatment Should You Choose?

Rejuran and Sculptra are both popular injectable treatments in Korea for improving signs of aging, but they work in very different ways. Rejuran focuses on skin repair and overall skin quality, while Sculptra is a collagen biostimulator designed to encourage gradual collagen production and restore facial structure. For foreign patients visiting Seoul, the right option depends on whether the main concern is thin, damaged skin or broader collagen and volume loss.



1. What Is the Difference Between Rejuran and Sculptra?

Although both treatments are sometimes described as collagen or regenerative treatments, their ingredients and purposes are different.

Rejuran

• Uses polynucleotides (PN) derived from purified salmon DNA.
• Supports skin repair and regeneration.
• Focuses on elasticity, texture, fine lines, and overall skin quality.
• Usually injected superficially into the skin.
• Does not aim to create significant facial volume.

Sculptra

• Uses poly-L-lactic acid (PLLA), a biodegradable collagen-stimulating material.
• Encourages the body to produce collagen gradually.
• Can improve wrinkles, firmness, and areas affected by facial collagen loss.
• Is injected deeper than a typical skin booster.
• May provide a subtle improvement in facial fullness as collagen develops.

Sculptra is officially classified as an injectable implant containing PLLA, and its FDA-approved indications include correction of facial wrinkles and fine lines in the cheek region.

The simplest distinction is Rejuran = skin repair and quality, while Sculptra = collagen stimulation and structural rejuvenation.

2. Which Treatment Is Better for Different Skin Concerns?

The best choice depends on what is changing in your skin.

Rejuran may be considered for:

• Thin or fragile-looking skin
• Fine lines
• Reduced elasticity
• Rough or uneven texture
• Dehydration combined with poor skin quality
• Skin that looks tired or stressed
• Early signs of aging
• Improving overall skin resilience

Rejuran is generally more appropriate when the goal is to make the skin itself healthier and more resilient, rather than adding volume.

Sculptra may be considered for:

• General collagen loss
• Loss of facial firmness
• Gradual facial volume depletion
• Deeper wrinkles and folds
• Reduced cheek fullness
• Skin that has become less dense with age
• Overall facial rejuvenation

Sculptra works over time rather than acting like a conventional hyaluronic acid filler. The treatment is designed to stimulate collagen gradually, and clinical information indicates that results can develop over several weeks and may last up to around 24 months.

If your primary concern is skin texture and resilience, Rejuran may be more relevant. If your concern is broader collagen and structural loss, Sculptra may be considered.

3. Rejuran vs Sculptra for Different Ages

Age can provide a general guideline, but it should not be the only factor used when selecting an injectable treatment.

In your 20s

Rejuran may be considered when the main concerns are skin quality, dehydration, texture, or early fine lines.

Sculptra is generally less likely to be necessary if there is little collagen or structural loss, although treatment decisions should be based on individual anatomy and medical assessment rather than age alone.

In your 30s

Both treatments may become relevant.

• Rejuran: skin quality, fine lines, elasticity, and early skin aging
• Sculptra: early collagen decline, firmness, and subtle structural changes

In your 40s

The difference between the two becomes more noticeable.

Rejuran can address skin quality and resilience, while Sculptra may be considered when declining collagen is accompanied by loss of firmness or facial fullness.

In your 50s and beyond

Sculptra may become more relevant when collagen and structural volume loss are significant, while Rejuran can still be useful for maintaining or improving skin quality.

However, neither treatment should be viewed as a substitute for surgery when there is substantial excess skin or advanced facial sagging.

The condition of your skin and facial structure matters more than your age alone.

4. Treatment Process, Results and Downtime

The treatment experience is different because the products are injected at different depths and have different mechanisms.

Rejuran treatment

A typical Rejuran session may include:

1. Consultation and skin assessment
2. Cleansing and skin preparation
3. Topical or local numbing
4. Multiple small injections into the treatment area
5. Cooling and soothing care

Temporary redness, swelling, tenderness, and small raised injection marks are common possibilities. These usually improve over several days, although recovery varies.

Rejuran's effects are gradual. Patients generally seek improvement in skin texture, elasticity, hydration, and resilience rather than an immediate change in facial contour.

Sculptra treatment

Sculptra generally involves:

1. Facial assessment and treatment planning
2. Cleansing and preparation
3. Numbing when appropriate
4. Injection of reconstituted PLLA into selected areas
5. Post-treatment massage or aftercare according to the treatment protocol

Temporary swelling, bruising, tenderness, or redness may occur. Because Sculptra is a collagen stimulator, the initial appearance should not be mistaken for the final result.

Collagen develops progressively, so Sculptra results are usually evaluated over weeks to months rather than immediately after injection. The FDA notes that clinical treatment may involve up to four injections and that results may last up to 24 months.

Patients should follow the clinic's specific aftercare instructions and avoid unnecessary pressure, heat, or irritation during the early recovery period.

5. How Much Do Rejuran and Sculptra Cost in Korea?

Prices vary depending on dosage, treatment area, injection technique, clinic, physician, and promotional offers.

As a general 2026 Seoul price guide:

Rejuran

• 1cc: approximately ₩150,000–₩300,000
• 2cc: approximately ₩200,000–₩500,000
• 4cc: approximately ₩400,000–₩800,000+
• Larger treatment plans: approximately ₩800,000–₩1,000,000+

Current Korean pricing references place a typical 2cc Rejuran Healer session around ₩199,000–₩480,000, although individual clinic prices can vary substantially.

Sculptra

• 1 vial: approximately ₩550,000–₩1,200,000
• 2 vials: approximately ₩1,000,000–₩1,800,000+
• Larger treatment plans: approximately ₩1,500,000–₩2,500,000+

Recent 2026 Korean clinic listings show Sculptra prices ranging from around ₩880,000 per vial at some clinics to ₩1,200,000 during certain promotional periods, demonstrating how widely prices can differ.

When comparing Korean clinic prices, foreign patients should confirm:

• Exact product
• Number of cc or vials
• Treatment area
• Injection technique
• Number of planned sessions
• Whether consultation and numbing are included
• Whether VAT is included
• Whether the price is promotional

A Rejuran session and a Sculptra vial are not equivalent units, so comparing only the headline price can be misleading.

6. Which Should Foreign Patients Choose in Korea?

The most useful way to compare the two is to identify whether your main concern is skin quality or collagen and structural loss.

Consider Rejuran if your priorities are:

• Skin repair
• Thin or stressed skin
• Fine lines
• Elasticity
• Texture
• Overall skin quality

Consider Sculptra if your priorities are:

• Collagen loss
• Facial firmness
• Gradual volume restoration
• Deeper wrinkles
• Reduced facial fullness
• Long-term structural rejuvenation

Some patients may eventually use both approaches because they address different aspects of aging. Rejuran can focus on the quality of the skin, while Sculptra can address deeper collagen and structural changes. However, combining treatments is not automatically necessary and should be planned according to the patient's anatomy and treatment goals.

For international patients visiting Seoul, ask the clinic to explain the exact product, dosage, injection depth, expected timeline, recovery period, and total cost before treatment. This is especially important because Korean clinics may use the term “collagen booster” for several different injectable products.

Frequently Asked Questions

Is Rejuran or Sculptra better for wrinkles?
Both may help improve the appearance of wrinkles, but they work differently. Rejuran is more focused on skin quality, while Sculptra stimulates collagen and may provide broader structural improvement.

Does Sculptra make the face bigger?
Sculptra is not intended to create the immediate volume effect of a traditional filler. Its gradual collagen stimulation can increase fullness in treated areas, so dosage and placement are important.

Is Rejuran a collagen treatment?
Rejuran can support processes associated with skin regeneration and collagen production, but its primary role is generally described as improving skin repair and quality rather than providing the structural collagen stimulation associated with Sculptra.

How many Sculptra sessions do I need?
Treatment plans vary. The FDA-approved information allows for up to four injection sessions in the indicated treatment regimen, with sessions scheduled about three weeks apart. Your clinician determines the appropriate plan based on your needs.

Can Rejuran and Sculptra be done together?
They can potentially be included in the same overall rejuvenation strategy, but combining or spacing them should be decided by a qualified medical professional based on the treatment areas and individual skin condition.

Can foreigners get Rejuran and Sculptra in Seoul?
Yes. Both treatments are widely available in Korean aesthetic and dermatology clinics. International patients should confirm the exact product, dosage, treatment area, and aftercare instructions before booking.

Final Thoughts

Rejuran and Sculptra are both used for age-related skin improvement, but they address different needs. Rejuran is more focused on skin repair and quality, while Sculptra is designed to stimulate collagen and support gradual structural rejuvenation.

For foreign patients visiting Korea, the key is to match the treatment with the type of aging you want to address, rather than choosing based only on popularity or price. A personalized consultation can determine whether your skin needs repair, collagen stimulation, or a combination of approaches.
