Introduction

South Korea has become one of the most popular destinations for international patients seeking advanced dermatology treatments. Korean skin clinics are well known for combining innovative technologies and personalized treatment plans to address various skin concerns, especially acne scars, uneven texture, and signs of aging.

For patients with acne scars, a single treatment is not always enough because scars can involve different layers of the skin. Some scars are caused by deep tissue attachments, while others are related to reduced collagen, poor skin quality, or uneven texture.

The combination of Subcision and Rejuran in Korea has gained attention among international patients because these treatments work in different ways. Subcision focuses on releasing the scar tissue that pulls the skin downward, while Rejuran supports skin regeneration and improves overall skin condition.

This guide explains how Subcision and Rejuran work, their benefits, treatment process, recovery, results, costs, and important information for foreigners planning acne scar treatment in Korea.

Understanding Subcision Treatment

What Is Subcision?

Subcision is a minimally invasive acne scar treatment designed to improve depressed scars caused by fibrous bands beneath the skin.

When acne scars form, internal scar tissue can attach the skin surface to deeper layers. These attachments create a pulling effect that causes visible skin depressions.

During Subcision treatment, a dermatologist uses a specialized needle or cannula to carefully separate these fibrous connections. This allows the depressed skin area to gradually rise and supports the natural healing process.

Subcision is commonly used for:

• Rolling acne scars
• Depressed acne scars
• Tethered scars
• Some boxcar scars
• Uneven skin depressions

How Subcision Works

Subcision works by addressing the structural cause of acne scars rather than only improving the surface appearance.

The treatment process helps:

• Release scar tissue attachments
• Lift depressed acne scars
• Create space for collagen formation
• Improve uneven skin contours
• Support natural skin healing

Because Subcision targets deeper scar structures, it is often recommended for patients whose acne scars cannot be improved effectively with surface treatments alone.

Understanding Rejuran Treatment

What Is Rejuran?

Rejuran is a popular skin rejuvenation injectable treatment widely used in Korean dermatology clinics. It contains polynucleotides (PN), which are purified DNA fragments used in aesthetic medicine to support skin repair and regeneration.

Unlike traditional dermal fillers that mainly add volume, Rejuran focuses on improving skin quality from within.

Rejuran is commonly considered for:

• Fine lines
• Uneven skin texture
• Enlarged pores
• Dry or weakened skin
• Reduced elasticity
• Skin recovery after procedures

How Rejuran Improves Skin Quality

Rejuran supports the skin’s natural regeneration process by encouraging healthier skin structure.

Potential improvements may include:

• Smoother skin texture
• Improved hydration appearance
• Better elasticity
• Healthier-looking complexion
• Enhanced skin quality

Results usually develop gradually as the skin regeneration process continues.

Why Combine Subcision and Rejuran in Korea?

Treating Acne Scars at Different Skin Levels

Acne scars often involve both structural damage and changes in skin quality.

Subcision mainly focuses on:

• Deep scar tissue
• Skin tethering
• Depressed scars

Rejuran mainly focuses on:

• Skin regeneration
• Collagen support
• Texture improvement
• Overall skin condition

By combining both treatments, dermatologists can address different aspects of acne scar concerns.

Benefits of Combining Subcision and Rejuran

The combination may provide benefits such as:

• Improved appearance of depressed acne scars
• Better skin texture
• Increased collagen support
• Smoother-looking complexion
• Improved skin elasticity
• More natural-looking rejuvenation

This combination is often considered by patients who want gradual improvement rather than dramatic changes.

Ideal Candidates

This combination may be suitable for international patients who have:

• Uneven skin texture
• Enlarged pores
• Reduced skin elasticity
• Post-acne skin concerns

Patients should have realistic expectations because acne scar treatments usually improve scars rather than completely remove them.

Patients Who Need Consultation First

A dermatologist consultation is important for patients with:

• Active severe acne
• Skin infections
• Recent aggressive procedures
• Certain skin conditions
• Pregnancy or breastfeeding concerns

The doctor will evaluate whether the combination treatment is appropriate.
