Is it possible to treat acne scars on sensitive skin?

I have thin, sensitive skin that often turns red.

Moreover, the old acne marks and scars remain, making the skin look even dirtier.

I want to get rid of my scars, but I'm hesitant to decide on an acne scar treatment because I'm worried it might irritate my skin too much. Are there any treatments that focus on regenerating only the scarred areas while minimizing pain or skin damage? I'm concerned that my skin might become more sensitive after the procedure, or that the redness might persist for a long time...

Also, considering the speed of scar regeneration, what is the appropriate interval between visits for the next procedure? As a working professional, it is difficult for me to take time off work, so I plan to clear my schedule in advance.

If there are any safe acne scar treatment methods that consider my skin condition rather than risky procedures, please provide detailed information. After reviewing your response, I would like to visit the clinic to receive a direct diagnosis from the director.
