Hi,
Yes, TCA cross uses high concentration of Trichloro-Acetic acid (TCA) to injure the skin to cause subsequent skin inflammation, healing and scar improvement. If incorrectly applied or applied in excessive amount, the TCA may indeed cause excessive skin damage resulting in additional scarring including keloid scars.
As with most aesthetic procedures, your doctor’s competence and experience will reduce potential side effects to the minimum.
Hope this helps!
