I am wondering when I should start treatment for the pitted marks on my cheeks and acne scars.

I have been increasingly self-conscious lately about the small pitted marks and redness remaining on my cheeks where acne used to be. Even with makeup on, the uneven skin texture is still visible when the light hits it, so I am writing to inquire because I would like to receive a proper consultation this time. I still occasionally get new breakouts; I am wondering if it is possible to start acne scar treatment in this condition, or if it is better to address the breakouts first before proceeding with the treatment. I have heard that the management methods for pitted scars and red marks are different, so I would like to know how you differentiate between them during the consultation. I would also like to ask about the typical recommended number of sessions for acne scar treatment and how often the sessions are spaced apart. I am also concerned about whether it will interfere with going to work if there is a period of redness or scabbing after the treatment. I would also appreciate it if you could advise me on how to cleanse and moisturize at home while I am undergoing acne scar treatment.
