TCA Cross (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) is a procedure used to address certain types of acne scars and improve skin texture. This article provides an overview of the TCA Cross acne scar treatment, the process involved, and general care considerations. It also outlines what to expect from TCA Cross treatment at Sozo Clinic in Singapore.

What is TCA Cross?

TCA Cross, or Trichloroacetic Acid Chemical Reconstruction of Skin Scars, is a targeted chemical peel treatment designed specifically for depressed acne scars. Available at Sozo Clinic in Singapore, this procedure involves applying a high concentration of TCA (70% – 100%) to specific areas of the skin. The treatment targets the deeper layers where scar tissue resides, aiming to stimulate collagen production and promote dermal thickening, which may improve the appearance of acne scars over time.

How TCA Cross Works and What Makes It Unique?

TCA Cross is a medium to deep chemical peel that may be effective in treating various types of acne scars, including ice pick scars, wrinkles, and signs of photo-ageing. The process involves applying a high concentration of TCA acid directly to the scar tissue, which denatures proteins in the deeper skin layers and encourages collagen synthesis. This specialised technique focuses on filling indented scars and requires precise handling due to the high acid concentration.

What distinguishes TCA Cross is its targeted approach to treating stubborn acne scars that may not respond as well to other treatments. While the treatment can lead to noticeable improvements in skin texture, results are gradual, and the degree of improvement can vary depending on the individual’s skin type, the severity of the scars, and the number of treatments received.

Types of Scars Treated by TCA Cross

TCA Cross is effective against various types of scars, making it a versatile option for those seeking acne scar treatments.
At Sozo Clinic, this TCA Cross treatment is customised to address the following:

treatment chemical applied
  • Ice-Pick Scars: TCA Cross can create a controlled injury to the skin, promoting collagen production that may help fill in these deep, narrow acne scars.
  • Boxcar Scars: By stimulating the skin’s healing response, TCA Cross may encourage the skin to rebuild and smooth out broad, rectangular depressions.
  • Rolling Scars: TCA Cross helps to break down the fibrous bands beneath the skin, allowing for a more even surface and potentially reducing the wave-like appearance of rolling scars.

Suitability for Various Skin Types

One of the strengths of TCA Cross is its adaptability to different skin types, tones, and acne scar conditions. Regardless of skin colour or texture, TCA Cross can be tailored to meet individual needs. 

At Sozo Clinic, patients receive a personalised approach that determines the appropriate concentration of TCA for their specific skin type and scar condition.

Cost of TCA Cross in Singapore

The cost of TCA Cross treatment in Singapore varies depending on factors such as the severity of the scars and the number of sessions required.
On average, patients may expect to pay around $300 per session.

The TCA Cross Process at Sozo Clinic

Understanding the procedure can help alleviate apprehensions and prepare patients for what to expect
during their TCA Cross treatment at Sozo Clinic. Here’s a detailed breakdown:

Step 1: Consultation

The first step is a comprehensive consultation with our doctor. During this session, the practitioner will assess your skin condition, discuss your goals, and determine the most appropriate concentration of TCA for your treatment. This consultation ensures that the procedure is tailored to your specific needs and skin type.

Step 2: The Procedure

Once the consultation is complete, the procedure begins with preparation. Patients are advised to cleanse their face thoroughly. The practitioner will then apply a topical anaesthetic (numbing cream) to minimise discomfort. The TCA Cross procedure involves using an applicator to apply the TCA at the base of the selected acne scar. The practitioner employs the “syringe-dropper” or toothpick methods to ensure controlled and precise application. The treated areas, known as “frosting,” will turn white, indicating the TCA’s action on the scar tissue.

Duration of Each Session

Each TCA Cross session typically lasts between 15 to 30 minutes. This short duration makes the procedure convenient for those with busy schedules, as it requires minimal time commitment.

Expected Sensations
During the Procedure

Patients may experience a warm, heating sensation in the treated areas during the procedure. This sensation is generally well-tolerated, with minimal discomfort. Post-procedure, applying an antibiotic ointment helps facilitate healing and reduces the risk of infection.

Step 3: Post-Treatment Care

Proper aftercare is crucial for maintaining the results of TCA Cross. The professionals at Sozo Clinic recommend the following tips:

  • Keep the Treated Area Clean: Clean the treated area with a mild cleanser to prevent infection.
  • Avoid Sun Exposure: Protect your skin from direct sunlight using high-SPF sunscreen and protective clothing.
  • Moisturise Regularly: Keep the skin hydrated with a gentle, non-comedogenic moisturiser to aid healing.

FAQs about TCA Cross Singapore

Redness typically lasts 3-5 days post-procedure. Collagen stimulation may take at least 3-4 weeks to develop, with results potentially becoming more noticeable at 3-4 months.

The number of sessions varies depending on the individual, scar location, and skin type. Generally, 2-4 sessions spaced about one month apart are recommended.

Some patients may observe a 1 to 2-grade improvement in their acne scars over six months, though results can vary.

Yes, TCA is a non-toxic chemical (trichloracetic acid) that has been used in skin peels for over 20 years.

TCA Cross is effective for treating acne scars, including deep scars and enlarged pores, because it targets areas that may be challenging for lasers to treat effectively. Lasers such as CO2, Erbium, and Fraxel can reach deep scars but may push the safety limits, especially for very deep acne scars like ice-pick scars.

TCA Cross overcomes these limitations by applying a precise concentration of trichloroacetic acid directly to the scar tissue. This process denatures the proteins in the scar tissue, stimulates collagen production, and helps to raise the level of the scar to match the surrounding skin.

While improvements may be noticeable after a single treatment, deeper scars, such as ice-pick scars, often require 2-3 treatments for optimal results. The concentration of TCA used—ranging from 35% to 100%—is chosen based on factors like skin type and scar depth, ensuring a tailored approach to achieve the best outcome.

The procedure is generally well-tolerated with only slight discomfort. A numbing cream is typically sufficient to minimise any discomfort during the treatment.

In some cases, TCA Cross may help reduce pore size. However, most patients will need 2-3 treatments to see a 30-50% reduction in pore size.

Yes, all skin types can be safely treated with TCA Cross. However, darker skin types, such as Asian skin, may have an increased risk of post-treatment darkening. Using sunscreen and a whitening cream can help reduce these risks.
