TCA CROSS and Subcision in Korea: Guide to Deep Acne Scar Treatment
Introduction
South Korea has become a leading destination for international patients seeking advanced acne scar treatments and aesthetic dermatology procedures. Korean dermatology clinics are known for using customized treatment combinations to address different types of acne scars, including deep scars, uneven texture, and depressed skin areas.
For patients with challenging acne scars, the combination of TCA CROSS and Subcision in Korea is a commonly considered treatment approach. These two procedures target different scar mechanisms and are often combined to improve the appearance of deep acne scars.
TCA CROSS focuses on stimulating collagen production inside narrow and deep acne scars, while Subcision works by releasing scar tissue attachments beneath the skin that pull the surface downward.
Together, these treatments may help improve the appearance of ice pick scars, rolling scars, and depressed acne scars.
This guide explains how TCA CROSS and Subcision work, their benefits, treatment process, recovery, results, costs, and important information for international patients planning acne scar treatment in Korea.
Understanding TCA CROSS Treatment
What Is TCA CROSS?
TCA CROSS (Chemical Reconstruction of Skin Scars) is a specialized acne scar treatment that uses a high concentration of trichloroacetic acid (TCA) applied directly into specific acne scars.
Unlike traditional chemical peels that are applied over a larger skin area, TCA CROSS targets individual scars to stimulate controlled skin regeneration.
TCA CROSS is commonly used for:
- Ice pick scars
- Narrow deep acne scars
- Small depressed scars
- Textural irregularities caused by acne
How TCA CROSS Improves Acne Scars
Deep acne scars often occur when collagen production is damaged after severe acne inflammation.
During TCA CROSS treatment, TCA is carefully applied inside the scar area. This creates controlled stimulation that encourages the skin’s natural healing response.
Potential benefits include:
- Increased collagen production
- Improved scar depth appearance
- Smoother-looking skin texture
- Better skin surface appearance
Because collagen remodeling takes time, improvements usually develop gradually after multiple treatments.
Understanding Subcision Treatment
What Is Subcision?
Subcision is a minimally invasive acne scar treatment that uses a specialized needle or cannula to release fibrous scar bands beneath the skin.
Some acne scars appear depressed because scar tissue attaches the skin surface to deeper layers. These attachments prevent the skin from returning to a smoother appearance.
Subcision is commonly used for:
- Rolling acne scars
- Depressed scars
- Tethered scars
- Uneven skin surfaces
How Subcision Works
During Subcision, the dermatologist carefully separates the scar tissue underneath the skin.
This releases the pulling force that creates skin depressions and allows the treated area to improve.
Potential benefits include:
- Reduced appearance of depressed scars
- Improved skin smoothness
- Better skin contour
- Support for collagen remodeling
Subcision is often combined with other treatments because different scar types require different approaches.
Why Combine TCA CROSS and Subcision in Korea?
Treating Different Types of Deep Acne Scars
Acne scars are not all the same. Different scar types require different treatment methods.
TCA CROSS mainly targets:
- Ice pick scars
- Deep narrow scars
- Individual scar depressions
Subcision mainly targets:
- Rolling scars
- Scar bands beneath the skin
- Depressed skin areas
By combining both procedures, dermatologists can address multiple scar patterns in one customized treatment plan.
Benefits of TCA CROSS and Subcision Combination
Potential benefits may include:
- Improved appearance of deep acne scars
- Smoother skin texture
- Better skin surface contour
- Increased collagen stimulation
- More balanced-looking complexion
The combination is often selected for patients who need more than one approach to improve complex acne scars.
