How do you distinguish between red marks and current blemishes during an acne consultation?

I am curious about the criteria used to distinguish between current breakouts and previous red or brown marks during an acne consultation. I have heard that even if they look similar on the surface, the treatment sequence may differ depending on whether there is residual inflammation or pigmentation changes. During the consultation, do you examine redness, heat sensation, pain, and the condition of the skin surface? I would also like to know which step—extraction, soothing, or moisturizing—is planned first when there are both areas with excessive sebum and dead skin cells alongside dry areas. Would it be helpful to organize and bring the cleansers, cosmetics, and exfoliation products I am currently using? I am also curious about the period during which I should take a break from functional products before and after treatment, as well as when I should resume washing my face and applying makeup. Please explain the timing for checking skin reactions after the first treatment, the criteria for determining the interval between subsequent visits, and any reactions that require me to inquire about again at the clinic.
