Reduce Deep Acne Scars and Smooth Skin Texture Over Time
A medically guided treatment designed to improve deep, pitted acne scars by stimulating collagen repair within the skin.
Your care begins with a doctor’s assessment.
What is TCA CROSS
TCA CROSS (Chemical Reconstruction Of Skin Scars) is a targeted chemical treatment used in the management of deep, pitted acne scars, particularly ice-pick scars.
It involves the precise application of high-concentration trichloroacetic acid (TCA) directly into individual scars.
This treatment is commonly used for:
- Ice-pick scars
- Deep, narrow acne scars
- Localised pitted scars
How TCA CROSS Works (Technology Explained)
TCA CROSS works by delivering controlled chemical stimulation directly into the scar.
Mechanism of action:
- TCA is applied precisely into each scar
- A controlled chemical reaction occurs within the scar tissue
- This stimulates collagen production and skin repair
- The scar gradually becomes shallower over time
Why this works for deep scars:
- Targets the base of the scar—not just the surface
- More precise than lasers for narrow, deep scars
- Designed to rebuild skin structure from within
What This Treatment May Help Improve
- Deep ice-pick acne scars
- Pitted or uneven skin texture
- Localised depressed scars
- Skin irregularities from past acne
Consult with our doctor to assess suitability.
Doctor-Led Assessment (Why It Matters)
Before treatment, your doctor will:
- Identify the type of acne scars (ice-pick, boxcar, rolling)
- Assess depth and severity
- Determine if TCA CROSS is appropriate
- Plan combination treatments if needed
This ensures targeted and personalised scar treatment.
