What do you check first during a consultation regarding red marks remaining after acne has subsided?

I would like to receive a consultation because redness seems to linger for a while even after the breakouts on my chin and cheeks have subsided. I haven't decided on a specific procedure yet, but I am curious how to differentiate between the condition of current breakouts and areas that have already cleared up. If photos look different depending on the time period, would it be helpful to include the lighting and date to aid the explanation? I also plan to keep a list of the cleanser and moisturizer I have recently used, as well as when I switched them.

I would like to know if the treatment scope is divided separately for areas with red marks that feel sensitive or dry, and if I receive guidance on visit intervals or home care precautions after my skin condition is assessed first. I would also like to ask specifically about daily routines, such as sun protection and cleansing. I would appreciate it if you could tell me whether the cost and required frequency can be determined after observing my skin condition and reaction, and what the criteria are for checking progress. Rather than starting in a hurry, I intend to take my time and decide after understanding the priorities and expected process.
