Tear Trough Fillers vs. Rejuran Treatment in Korea: Which Is Better?

Introduction

Dark circles, hollow under-eyes, and tired-looking eyes are some of the most common aesthetic concerns among people seeking facial rejuvenation treatments. Because the under-eye area is delicate and complex, choosing the right treatment depends on the main cause of the concern.

In South Korea, two popular non-surgical under-eye treatments are tear trough fillers and Rejuran. While both treatments can improve the appearance of the under-eye area, they work in completely different ways. Tear trough fillers focus on restoring lost volume and reducing shadows, while Rejuran focuses on improving skin quality, elasticity, and regeneration.

Korean dermatology clinics commonly recommend these treatments for different types of under-eye aging. Some patients may benefit from one treatment alone, while others may achieve better results with a combination approach.

This guide compares tear trough fillers vs. Rejuran treatment in Korea, including how they work, benefits, differences, recovery, costs, and how to choose the right option.

Understanding Under-Eye Aging Concerns

Why Do Under-Eyes Look Older?

The under-eye area can show signs of aging earlier because the skin is naturally thin and has less collagen compared with other facial areas.

Common concerns include:

  • Tear trough hollows
  • Dark circles
  • Fine lines
  • Thin skin
  • Crepey texture
  • Loss of elasticity
  • Tired-looking eyes

The best treatment depends on whether the main problem is volume loss or skin quality decline.

What Are Tear Trough Fillers?

How Tear Trough Fillers Work

Tear trough fillers are injectable treatments designed to restore volume beneath the eyes.

Most fillers use hyaluronic acid, a substance naturally found in the body that helps maintain hydration and volume.

The treatment works by:

  • Filling hollow areas
  • Reducing under-eye shadows
  • Smoothing the transition between the lower eyelid and cheek
  • Creating a more refreshed appearance
Benefits of Tear Trough Fillers

Tear trough fillers may help improve:

  • Deep under-eye hollows
  • Shadow-related dark circles
  • Sunken appearance
  • Facial imbalance caused by volume loss

Results are usually visible shortly after treatment.

Who Is a Good Candidate for Tear Trough Fillers?

Fillers may be suitable for people who have:

  • Visible tear trough hollows
  • Volume loss under the eyes
  • Shadowing caused by facial structure
  • A sunken or tired appearance

However, fillers may not be the best option for patients whose main concern is thin, wrinkled, or crepey skin.

What Is Rejuran Treatment?

How Rejuran Works

Rejuran is a regenerative injectable treatment widely used in Korean dermatology clinics.

It contains polynucleotides (PN), which are designed to support skin repair and improve overall skin condition.

Unlike fillers, Rejuran does not add volume. Instead, it focuses on improving the quality and strength of the skin.

Benefits of Rejuran Under the Eyes

Rejuran may help improve:

  • Thin under-eye skin
  • Fine wrinkles
  • Skin elasticity
  • Hydration
  • Skin texture
  • Overall skin resilience

Results develop gradually as the skin improves over time.

Who Is a Good Candidate for Rejuran?

Rejuran may be suitable for people with:

  • Thin under-eye skin
  • Fine lines
  • Crepey texture
  • Early signs of aging
  • Poor skin quality

It is often chosen by patients who want natural skin improvement rather than volume enhancement.

Which Treatment Is Better for Dark Circles?

Dark Circles Caused by Hollowing

If dark circles are mainly caused by tear trough depression and shadowing, fillers may provide better improvement.

Fillers work by:

  • Restoring volume
  • Reducing shadows
  • Improving facial contour
Dark Circles Caused by Thin Skin

If dark circles are related to thin skin or visible blood vessels, Rejuran may be more appropriate.

Rejuran focuses on:

  • Strengthening skin quality
  • Improving elasticity
  • Supporting regeneration

Some patients may require a combination approach.

Which Treatment Is Better for Under-Eye Wrinkles?

Tear Trough Fillers

Fillers may slightly improve wrinkles caused by volume loss, but they are not primarily designed for skin texture improvement.

Rejuran

Rejuran is often preferred for:

  • Fine lines
  • Thin skin
  • Crepey texture
  • Reduced elasticity

It supports gradual improvement in skin condition.

Combination Treatment: Fillers + Rejuran

Why Korean Clinics Combine Treatments

Some patients have both volume loss and poor skin quality.

For example:

  • Hollow under-eyes create shadows
  • Thin skin creates wrinkles
  • Reduced elasticity makes the area look older

In these cases, Korean dermatologists may combine:

  • Tear trough fillers for volume restoration
  • Rejuran for skin improvement

This approach addresses both structure and skin quality.
