Acne scars, especially those that delve deep into the skin’s layers, can be a persistent reminder of past skin troubles. In the pursuit of flawless skin, various treatments have emerged, and among them, TCA Cross has gained prominence for its efficacy in addressing deep acne scars. 

This comprehensive guide explores the nuances of TCA Cross, from its application to its effectiveness, risks, and availability in Singapore.

Types of Deep Acne Scars

Before delving into the solution, understanding the problem is paramount. Deep acne scars manifest in different forms, and recognising their distinct types is crucial for tailoring an effective treatment plan.

  • Icepick Scars: Narrow, V-shaped scars that penetrate deep into the skin.

What is TCA Cross?

Trichloroacetic Acid (TCA) Cross is a dermatological procedure designed to treat deep acne scars. It involves the precise application of TCA onto the scar, stimulating collagen production and promoting skin regeneration. This targeted approach makes it particularly effective for scars that extend into the dermis, addressing the issue at its core.

Why TCA Cross is Effective for Deep Acne Scars

The effectiveness of TCA Cross lies in its ability to target the scar’s depth. Unlike surface treatments, TCA Cross penetrates deep into the layers of the skin, stimulating collagen remodeling. 

Collagen, a key structural protein, plays a pivotal role in maintaining skin elasticity and structure. By encouraging collagen production, TCA Cross facilitates the gradual filling and smoothing of deep acne scars.

How TCA Cross Works

  1. Precise Application: A high concentration of TCA is precisely applied to the base of each scar using a fine-tipped applicator.
  2. Collagen Stimulation: TCA induces controlled injury at the scar site, triggering the body’s natural healing response. This leads to the production of new collagen fibers.
  3. Filling and Smoothing: As collagen remodels, the scar gradually fills, and the skin surface becomes smoother over time.

Risks and Considerations for TCA Cross Treatment

While TCA Cross is generally considered safe, it is essential to be aware of potential risks and considerations associated with the procedure.

  • Hyperpigmentation: Darkening of the treated area may occur, especially in individuals with darker skin tones. Proper sun protection is crucial post-treatment.
  • Hypopigmentation: In some cases, the treated area may become lighter than the surrounding skin.
  • Infection and Scarring: Improper application or inadequate post-care can lead to infection or undesirable scarring.
  • Multiple Sessions Required: Achieving optimal results often necessitates multiple sessions, spaced several weeks apart.

Before undergoing TCA Cross, individuals should consult with a qualified aesthetic physician to assess their suitability for the treatment and discuss potential risks based on their skin type and medical history.
