What Is TCA CROSS?

TCA CROSS is a minimally invasive dermatologic procedure designed to improve deep acne scars by stimulating collagen production within the scar.

The treatment involves carefully applying a concentrated trichloroacetic acid (TCA) solution directly into individual acne scars.

TCA CROSS is commonly used for:

• Ice pick scars
• Deep acne scars
• Narrow boxcar scars
• Atrophic acne scars
• Post-acne skin depressions
• Acne scar revision
• Scar remodeling
• Skin texture improvement

The procedure is widely performed by acne scar specialists throughout Hongdae and Seoul.

How TCA CROSS Works

TCA CROSS works by creating a controlled chemical reaction inside the scar.

This process stimulates:

• New collagen production
• Tissue remodeling
• Scar elevation
• Skin regeneration

During treatment:

• Individual scars are identified
• TCA solution is precisely applied into each scar
• Controlled inflammation stimulates healing
• Collagen gradually develops during recovery

Over time, the scar may become shallower and less noticeable.

Types of Acne Scars Treated with TCA CROSS

Ice Pick Scars

TCA CROSS is considered one of the most commonly used treatments for:

• Deep ice pick scars
• Narrow acne scars
• Pitted acne scars

Ice pick scars often respond better to TCA CROSS than many other treatment methods.

Narrow Boxcar Scars

May help improve:

• Sharp-edged scars
• Small depressed scars
• Localized textural defects

Mixed Acne Scarring

Many patients have a combination of:

• Ice pick scars
• Rolling scars
• Boxcar scars

TCA CROSS is often incorporated into broader acne scar treatment programs.

Acne Scar Types Less Suitable for TCA CROSS

Rolling Scars

Rolling scars are typically caused by fibrous scar bands beneath the skin.

These scars often respond better to:

• Subcision
• RF microneedling
• Combination treatments

Broad Depressed Scars

May require:

• Fractional laser resurfacing
• RF microneedling
• Collagen stimulation therapies

A dermatologist can determine the most appropriate treatment strategy.

Benefits of TCA CROSS

Potential benefits may include:

• Improvement of ice pick scars
• Improvement of narrow boxcar scars

TCA CROSS is particularly valued for treating scar types that can be difficult to improve with lasers alone.
