About TCA:

Requires multiple sessions. Typically there is about 10% improvement per session. Usually 3 to 4 sessions are required and then a laser resurfacing is recommended to optimize the results. 

May cause brown or red pigmentation changes, which are temporary. You may require bleaching cream to be used every night. If you get the red pigmentation, it will go away on its own but may require months. This typically happens in darker skin individuals. 

Collagen Stimulation: Maximum results are seen about 3 to 4 months after every treatment since it takes time to build collagen inside the skin. So it takes time so please be patient. You will see your best result 3 months after the last treatment.
