TCA Cross technique is the application of Trichloroacetic Acid 100%
into ice pick or boxcar scars, stimulating collagen production in the
scar. It is very effective but may need to be repeated multiple times,
typically 3 times. Patients can experience significant improvement. It
is safe in all skin colors however one must be careful in darker skin
In darker skin individuals, a test spot is performed. If there are no
side effects, then the TCA CROSS technique can be performed on the
entire face. Bleaching cream can be used before and after the procedure.
