TCA CROSS
A precise, spot-applied technique using high-strength TCA to treat deep, narrow ice-pick acne scars that broader peels and lasers do not fully resolve.
How it works
A concentrated trichloroacetic acid solution is applied with a fine applicator into the base of each individual ice-pick scar (CROSS: Chemical Reconstruction Of Skin Scars), triggering focused collagen repair at the scar itself without treating the surrounding skin.
Areas we treat
Deep, narrow ice-pick acne scars specifically; broader or shallower scarring is better suited to Acne & Scars or microneedling.
The session and aftercare
15-20 minutes, small dark scabs at each treated point that flake off over about a week. A course of 3-4 sessions, 6-8 weeks apart, is typical.
Who it suits
- Deep, narrow ice-pick acne scars specifically
- Already tried broader resurfacing without full improvement
- Able to plan around small visible scabbing for about a week
Why TCA CROSS suits ice-pick and boxcar scarring
TCA CROSS (Chemical Reconstruction of Skin Scars) applies a high concentration of trichloroacetic acid to the base of individual atrophic scars, triggering a controlled, localised wound-healing response that raises the scar floor over several weeks. It is most effective for narrow ice-pick and boxcar acne scars that have not responded well to resurfacing lasers or microneedling alone, and is often combined with those treatments as part of a longer scar-revision plan.

Frequently asked questions
What is TCA CROSS?
CROSS stands for Chemical Reconstruction Of Skin Scars. A concentrated trichloroacetic acid solution is applied with a fine applicator into the base of each individual ice-pick scar, triggering focused collagen repair at the scar itself without treating the surrounding skin.
How much does TCA CROSS cost in the Maldives?
Pricing depends on how many scars are being treated and the number of sessions needed; confirmed after assessment at consultation.
How many TCA CROSS sessions will I need?
A course of 3-4 sessions, 6-8 weeks apart, is typical, since each treated point needs time to fully remodel before repeating.
Does TCA CROSS hurt?
There is a brief stinging sensation as the acid is applied to each point; it passes quickly and numbing can be used if needed.
What is the downtime?
Small dark scabs form at each treated point and flake off over about a week; these should not be picked to avoid scarring.
When will I see results from TCA CROSS?
Improvement builds gradually across the course as each treated scar remodels; visible flattening is usually clearer after 2-3 sessions.
What are the risks of TCA CROSS?
Because the acid is applied only to the base of each scar and not the surrounding skin, risk to normal skin is low; temporary darkening (hyperpigmentation) at treated points is possible, especially without proper sun protection.
Is TCA CROSS right for all types of acne scars?
It is specifically for deep, narrow ice-pick scars. Broader or shallower scarring responds better to microneedling, fractional laser or a combined Acne & Scars plan.
