Inquiry regarding basic care and precautions to be checked during a skin care consultation

I would like to inquire about what information is generally helpful to check before a skin care consultation. This is not a review based on specific skin symptoms or treatment experience, but rather a question regarding basic care and consultation preparation. I would like to know the criteria used to determine the necessity of moisturizing care or treatment based on skin condition, and to what extent I should share information regarding cosmetics I normally use, allergies, or medications I am taking during the consultation. Please also provide guidance on common precautions regarding cleansing, moisturizing, and sun protection habits, as well as the criteria for discontinuing product use and seeking medical attention if irritation occurs after application. If I am recommended a treatment, I would like to know the best order to check not only the expected changes but also side effects, recovery time, additional costs, and aftercare. I understand that individual diagnoses and treatment plans must be determined through consultation with medical staff, but I would appreciate guidance to assist with general consultation preparation. ※ This is a general inquiry, not a review of an actual treatment experience, and an AI tool was used to organize the question.
