How are the basic treatment composition and discontinuation criteria explained during a skincare consultation?

I would like to inquire about the general procedure when preparing for a skincare consultation, as I would like to know the actual order of treatment and adjustment criteria based on skin condition, rather than just looking at the names or frequency of treatments. Assuming a personalized diagnosis is necessary, I would like to know what items are checked during the first visit.

Could you please explain which steps are included in the basic package, such as cleansing, exfoliation, extraction, moisturizing, and soothing? I would also like to know if the steps are not performed all at once, or if the order is changed or some are omitted based on the skin condition assessed on the day. I am also curious if the treatment is immediately switched to a different one if a specific step is deemed unsuitable, or if it is possible to reschedule after just the consultation.

If I report discomfort such as stinging or a burning sensation during the procedure, can I be informed of the procedure to pause and check, and can I be guided to distinguish between expected reactions after treatment and reactions requiring contact with the hospital? I would also like to inquire if it is possible to receive a separate informational letter.

Finally, it would be helpful for planning if you could explain the steps and options included in the basic cost, additional costs for soothing care, and the point at which progress is evaluated before scheduling the next visit.
