What Is TCA CROSS?

TCA CROSS is a chemical scar reconstruction technique used mainly for narrow, deep acne scars. A doctor applies a small amount of trichloroacetic acid directly into the scar pit rather than across the whole face.

The treated scar forms a controlled wound response. Over time, collagen remodeling may help lift and soften the scar. Results are gradual, and several sessions are usually needed.

What TCA CROSS Treats

TCA CROSS may be used for:

• Ice pick acne scars
• Narrow deep acne scars
• Small pitted scars
• Selected boxcar scars
• Enlarged scar-like pores
• Deep facial acne pits
• Old acne scars that do not improve with creams
• Small chickenpox-like depressed scars in selected cases
• Acne scars on the cheeks, temples, forehead, chin, or nose
• Mixed acne scars when combined with other treatments

TCA CROSS is usually not the best standalone treatment for broad rolling scars, tethered scars, widespread uneven texture, or redness. Those concerns may need subcision, laser, RF microneedling, vascular laser, or combination treatment.

Common TCA CROSS Treatment Areas in Busan

1. Cheeks

The cheeks are one of the most common areas for TCA CROSS because ice pick and boxcar acne scars often appear there.

2. Temples

Temple scars may be treated with TCA CROSS when they are narrow and deep, although skin thickness and scar type must be assessed carefully.

3. Forehead

Forehead scars may be treated if they are small and pitted. Careful technique is needed to avoid pigmentation changes.

4. Chin

TCA CROSS may help selected pitted acne scars on the chin.

5. Nose

TCA CROSS may be used for enlarged scar-like pores or narrow acne pits on the nose in selected patients.

6. Jawline

Jawline acne scars may need TCA CROSS, subcision, laser, or RF microneedling depending on whether the scars are pitted, tethered, or textural.

TCA CROSS Diagnosis and Scar Assessment

1. Acne Scar Consultation

A dermatologist evaluates scar type, scar depth, skin tone, active acne, pigmentation risk, previous treatments, and realistic improvement goals.

2. Scar Type Classification

The doctor checks whether scars are ice pick, boxcar, rolling, tethered, hypertrophic, or mixed. TCA CROSS is most useful for narrow ice pick scars.

3. Skin Type and Pigmentation Risk Review

Patients with darker skin types or a history of hyperpigmentation may need careful treatment strength, test spots, pre-treatment skincare, and strict sun protection.

4. Active Acne Evaluation

Active acne should often be controlled before aggressive scar treatment to reduce new scarring and inflammation.

5. Previous Treatment Review

The doctor may ask about past lasers, chemical peels, isotretinoin, microneedling, fillers, subcision, or previous TCA treatment.

6. Combination Treatment Planning

Because acne scars are often mixed, the clinic may recommend TCA CROSS with subcision, laser, RF microneedling, microneedling, fillers, or skin boosters.

• Severe ice pick scars: 5–8+ sessions

Potential Benefits of TCA CROSS

Potential benefits may include:

• Improved ice pick acne scars
• Softened narrow deep scars
• Gradual collagen remodeling
• Better appearance of pitted scars
• Targeted treatment with limited surrounding skin exposure
• Can be combined with acne scar lasers
• Can be combined with subcision for mixed scars
• Can help scars that do not respond well to creams
• Minimal full-face downtime compared with aggressive peels
• Personalized acne scar treatment planning
• Improved skin confidence over time

TCA CROSS vs Subcision

TCA CROSS and subcision treat different acne scar types.

TCA CROSS is often better for:

• Ice pick scars
• Narrow deep pits
• Small sharp-edged scars
• Enlarged scar-like pores

Subcision is often better for:

• Rolling scars
• Tethered scars
• Depressed scars caused by fibrous bands
• Scars that improve when the skin is stretched

Many patients need both treatments if they have mixed acne scars.

TCA CROSS vs Laser Acne Scar Treatment

TCA CROSS targets individual deep scar pits. Laser treatments are often used for wider texture improvement, scar edges, pores, redness, and collagen remodeling.

TCA CROSS may be combined with:

• Fractional CO2 laser
• Erbium laser
• RF microneedling
• Vascular laser
• Pigment laser
• Microneedling
• Skin boosters
• Subcision
• Fillers

Combination treatment may provide better results than one method alone for mixed scar patterns.

What to Expect During TCA CROSS

A dermatologist or acne scar specialist cleans the skin and identifies which scars should be treated. Numbing cream may be used depending on sensitivity and treatment area.

A tiny amount of TCA is applied directly into each scar using a fine applicator. The scar may turn white or frosted briefly, which is part of the controlled chemical reaction. A mild burning or stinging sensation may occur.

After treatment, the area may become red, darker, scabbed, or slightly swollen. Scabs usually form and fall off naturally. It is important not to pick them because picking can worsen scarring or pigmentation.

Recovery and Aftercare

After TCA CROSS, patients may be advised to:

• Keep the treated area clean
• Avoid picking scabs
• Avoid harsh scrubs and exfoliants
• Avoid retinoids or acids until cleared
• Use gentle moisturizer
• Use sunscreen every day
• Avoid strong sun exposure
• Avoid sauna, hot baths, and heavy sweating temporarily
• Avoid makeup until allowed if scabs are open
• Follow any prescribed ointment or skincare plan
• Contact the clinic if there is pus, severe pain, spreading redness, or delayed healing
• Return for repeat sessions only after the skin has healed

Healing may take several days to two weeks depending on the number of scars treated, skin type, treatment strength, and aftercare.

Before TCA CROSS, patients should:

• Choose a clinic experienced in acne scar treatment
• Ask whether your scars are suitable for TCA CROSS
