Under-eye concerns like hollowness, dark circles, and fine lines are among the top reasons patients visit skin clinics in Seoul. Two of the most common treatments are Under-Eye Rejuran (a regenerative skin booster) and Under-Eye Filler (tear trough filler). A key question many patients ask is:

Which one costs less—and which one delivers better value?



In this guide, we compare the costs, purposes, and typical outcomes so you can decide with confidence.

What Is Under-Eye Rejuran?

Under-Eye Rejuran is a skin booster injection made from polynucleotides (PN) designed to improve under-eye skin quality. It works by stimulating collagen, enhancing hydration, and strengthening skin texture.

Primary benefits:

• Improves fine lines
• Hydrates and smooths thin skin
• Reduces texture-related shadows

Unlike filler, Rejuran does not add volume.

What Is Under-Eye Filler?

Under-Eye Filler (tear trough filler) uses a soft hyaluronic acid or similar filler to add volume under the eye and soften hollows or shadows.

Primary benefits:

• Corrects structural hollowness
• Reduces dark shadow appearance caused by volume loss
• Improves transition between cheek and under-eye

Direct Cost Comparison

Below is a simplified cost comparison based on typical Seoul clinic pricing:

Under-Eye Rejuran:

• ₩300,000 – ₩600,000 per session
• Multiple sessions often recommended
• Approximate yearly cost (2–3 sessions): ₩900,000 – ₩1,800,000

Under-Eye Filler:

• ₩250,000 – ₩800,000 per syringe
• Most patients use 0.5–1.0 cc per side
• Typical total cost: ₩500,000 – ₩1,500,000

Summary:
In many cases, a single session of Under-Eye Rejuran is similarly priced or slightly more expensive than a single syringe of under-eye filler. However, because Rejuran typically requires multiple sessions for best results, its cumulative cost over time may be higher than filler, depending on how many treatments you receive.

Why the Costs Differ

Under-Eye Rejuran

• Works gradually
• Usually part of a treatment course
• Focuses on skin regeneration

Under-Eye Filler

• Immediate volume correction
• Often completed in a single session
• Price depends on volume used

Because Rejuran treats skin quality (texture and hydration) rather than volume, many clinicians recommend it as a complementary treatment to filler, especially where skin thinness is a concern.

Which One Offers Better Value?

Choose Under-Eye Rejuran if:

• Your primary concern is fine lines and skin quality
• You want improved elasticity and hydration
• You prefer regenerative results without added volume

Choose Under-Eye Filler if:

• Your main concern is hollowness or deep shadows
• You want immediate improvement
• You need structural support under the eye

Some patients do both — Rejuran first (for improved skin quality), then filler for volume — which often delivers the best overall outcome, though the cost will be higher.

So Is Rejuran Cheaper?

Short answer:
If comparing single treatments, Under-Eye Rejuran and Under-Eye Filler are often similar in price. Under-Eye Rejuran can be slightly more expensive per session, and total cost can become higher if multiple Rejuran sessions are needed.

Long-term view:
Under-Eye Filler is usually less expensive overall if only 1–2 syringes are needed and no additional sessions are planned.

Final Thoughts

Cost is important, but the best treatment depends on your specific concern. Hollowness due to volume loss usually responds better to filler, while skin quality issues — dryness, fine lines, crepey skin — benefit more from Rejuran.

A professional consultation is the best way to determine which approach (or combination) gives you the most value for your goals and budget.
