Pico Toning Consultation: What criteria are used to distinguish between melasma and acne marks?

I am writing to inquire about the process of distinguishing pigmentation while looking into a Pico Toning consultation at Maypure. It is easy to mistake all brown marks on the cheeks for the same blemish, but I have heard that the treatment plans may differ for melasma, freckles, and acne scars. I would like to know how, during a first visit, you assess not only the intensity of the color but also its location, boundaries, and changes over time.

I would also like to ask about the materials I should prepare before the consultation. I am curious if comparing old photos with recent ones is helpful, and whether I should remove my makeup and take photos under the same lighting conditions. Should I bring the ingredient lists for any whitening cosmetics or exfoliation products I have recently used? Please explain if there are cases where moisturizing care or monitoring is recommended before a procedure, depending on the skin condition.

If multiple types of pigmentation are present, I would like to know if they are all treated on the same day using a single method, or if the goals and sequence are divided by area. Rather than determining the number of sessions from the start, I would like to know at what point progress is evaluated and the plan is adjusted. I am also curious how to distinguish between a temporary darkening of the skin after the procedure and a reaction that requires contacting the clinic. I would appreciate it if you could provide details on the preparations required for a consultation appointment and clearly separate the costs for the examination and procedure. 습니다.
