TCA CROSS
TCA CROSS is a targeted chemical reconstruction technique used primarily for the treatment of selected atrophic acne scars, particularly ice-pick scars and certain narrow, deep acne scars.

What is TCA CROSS?
TCA CROSS stands for Trichloroacetic Acid Chemical Reconstruction Of Skin Scars.
A high-concentration trichloroacetic acid (TCA) solution is carefully applied directly into selected acne scars.
How TCA CROSS works
The treatment is based on controlled chemical reconstruction.
The doctor applies TCA precisely into selected atrophic scars, particularly narrow, deep scars.
The controlled injury can trigger a healing response involving:
- Collagen production
- Tissue remodelling
- Fibroblast activity
- Gradual improvement in scar depth
What results should patients expect?
TCA CROSS generally produces gradual improvement rather than complete removal of scars.
Over time, patients may notice:
- Deep scars appear shallower
- Scar edges become less noticeable
- Improved overall skin texture
- Reduced visibility of individual acne scars
The degree of improvement depends on:
- Scar type
- Scar depth
- Skin type
- Number of treatments
- Healing response
- Post-treatment care
Recovery and common effects
TCA CROSS intentionally creates a controlled chemical injury, so some visible recovery is expected.
Patients may experience:
- White frosting at the treatment sites immediately after application
- Redness
- Swelling
- Darkening or crusting of treated scars
- Temporary sensitivity
- Peeling or flaking
- Temporary pigmentation changes
Small treated areas may form crusts that naturally separate as the skin heals.
