The Gold-Standard for Deep Acne Scars in Malaysia
TCA Cross at Renora Clinic targets ice pick, boxcar, and deep rolling scars at their root — delivering up to 90% scar reduction with minimal downtime.
What Is TCA Cross?
The Science Behind Scar Reconstruction
TCA Cross stands for Trichloroacetic Acid Chemical Reconstruction of Skin Scars. It is a highly targeted, clinically proven procedure specifically designed to treat the most stubborn forms of acne scarring — ice pick scars, deep boxcar scars, and narrow rolling scars.
Unlike surface treatments such as chemical peels or standard laser resurfacing, TCA Cross delivers a concentrated drop of medical-grade trichloroacetic acid directly into the base of each individual scar. This triggers a controlled inflammatory response deep in the dermis, stimulating the production of new collagen from the bottom up.
The result? Scars are gradually filled in and raised as new collagen remodels the tissue beneath the skin's surface — delivering visible, lasting improvement that standard treatments simply cannot match.

Which Acne Scars Does TCA Cross Treat?
Not all acne scars respond to the same treatment. TCA Cross is specifically engineered for deep, atrophic scarring that other treatments fail to reach.
Ice Pick Scars
Narrow, deep, puncture-like channels extending into the dermis. The most challenging scar type — and TCA Cross's greatest strength. Responds exceptionally well to the procedure.
Boxcar Scars
Wider depressions with sharply defined vertical edges, creating a cratered appearance. TCA Cross targets the floor of each scar to stimulate upward collagen growth.
Rolling Scars
Broad, shallow depressions with sloping edges creating a wave-like texture. TCA Cross is most effective for the narrow, deep variants — often combined with subcision for rolling scars.
The Procedure
How TCA Cross Works at Renora Clinic
Every TCA Cross session at Renora Clinic follows a precise, medically supervised protocol to ensure safety, accuracy, and maximum results.
Skin Assessment & Consultation
Our doctors analyse your scar type, depth, skin tone, and history to determine the ideal TCA concentration (70%–100%) and a personalised treatment plan.
Precision Application
Using a fine-tipped applicator, a concentrated drop of TCA is placed precisely at the base of each individual scar — without affecting surrounding healthy skin.
Controlled Frosting
Within seconds, a white "frost" forms at the scar base — confirming the acid is penetrating deep into the dermis and triggering the collagen cascade.
Collagen Remodelling
Over 4–8 weeks, the body synthesises new collagen from the scar floor upward — progressively filling the depression. Results improve with each session.
Aftercare & Support
Renora Clinic provides full post-treatment guidance, skincare protocols, and follow-up consultations to maximise your healing and results.
Repeat & Refine
Most patients complete 3–6 sessions spaced 4–6 weeks apart. Each session builds on the last, with cumulative improvements in scar depth and skin texture.

Treatment Comparison
How TCA Cross Compares to Other Acne Scar Treatments
| Treatment | Best For | Depth Reached | Downtime | Sessions |
|---|---|---|---|---|
| TCA Cross Best for Ice Pick | Ice pick, narrow boxcar scars | Deep dermis | 3–7 days | 3–6 |
| Fractional Laser | Surface texture, mild scars | Superficial–mid dermis | 5–10 days | 3–5 |
| Microneedling | Rolling scars, large pores | Mid dermis | 1–3 days | 4–6 |
| Subcision | Rolling scars with fibrosis | Subcutaneous | 3–5 days | 2–4 |
| Chemical Peel | Surface pigmentation | Superficial | 3–7 days | 4–8 |
For ice pick scars specifically, TCA Cross has no equal — reaching depths no laser or surface peel can safely target.
