How are the skin condition prior to extraction and the criteria for delaying the process checked during a skincare consultation?

I would like to inquire about the criteria for determining whether extraction management is necessary during a skincare consultation. This is not a review regarding specific symptoms or treatment experiences, but a general question asking what should be checked during the initial consultation.

How do you distinguish between cases where immediate extraction is performed even on visible sebum, and cases where a different treatment is chosen after examining the skin condition first? Can I also receive guidance on criteria for reducing the scope of treatment on the same day or postponing it based on the presence of inflammation or irritation? I would also like to know what information I should prepare before the consultation if I use any exfoliation products at home or have any prescribed medications.

I would like to know when and how to resume cleansing, moisturizing, and sun protection after the treatment, as well as what to check before using my usual products again. I would also like to ask if you can differentiate between expected temporary reactions and reactions that require contacting the clinic for verification. Please also inform me whether the next visit can be adjusted based on my skin's recovery status, rather than following a fixed schedule.
