TCA Cross for Acne Scars
Deep acne scars can be difficult to treat. One highly specialized technique designed specifically for these scars is TCA Cross.
What Is TCA CROSS?
TCA CROSS stands for: Trichloroacetic Acid – Chemical Reconstruction of Skin Scars
It is a precise, in-office procedure designed to improve the appearance of deep, narrow acne scars, especially:
- Ice pick scars
- Very narrow boxcar scars
Instead of applying acid to the entire face (like a traditional chemical peel), TCA CROSS involves placing a high concentration of trichloroacetic acid directly into the base of individual scars.
This controlled chemical stimulation encourages:
- Collagen remodeling
- Gradual filling of the scar
- Visible softening over time
What Types of Acne Scars Does TCA CROSS Treat?
Understanding scar type is essential. Not all acne scars respond to the same treatment.
Best Candidates for TCA CROSS
✔ Ice pick scars (deep and narrow)
✔ Small, sharply defined boxcar scars
✔ Scars that did not improve with microneedling alone
Not Ideal For
✘ Broad rolling scars
✘ Raised (hypertrophic or keloid) scars
✘ Active inflammatory acne
In many cases, optimal acne scar correction involves combining treatments such as:
How TCA CROSS Works
Ice pick scars extend deeply into the dermis. Surface-level treatments often cannot reach the full depth of the scar.
During TCA CROSS:
- The skin is cleansed.
- A fine applicator precisely delivers high-strength TCA into the base of the scar.
- A brief frosting reaction occurs.
- The treated area forms a small scab over several days.
- Collagen remodeling begins beneath the surface.
Over multiple sessions, the scar gradually becomes shallower and less noticeable. This process does not “erase” scars, but it may significantly soften their depth and visibility. Results vary by individual.
How Many Sessions Are Needed?
TCA CROSS is usually performed in a series. Most patients require:
- 2–4 treatments
- Spaced about 4–6 weeks apart
The number of sessions depends on:
- Scar depth
- Scar density
- Skin type
- Response to treatment
Is TCA CROSS Safe?
When performed by a trained dermatology professional, TCA CROSS is generally safe and controlled.
However, risks may include:
- Temporary hyperpigmentation
- Hypopigmentation (rare but possible)
- Scarring (uncommon when properly performed)
- Prolonged redness
Proper patient selection and technique are critical — particularly for individuals with darker skin tones.
