I would like to know the criteria for selecting and reapplying sunscreen, and what should be checked during the consultation.

I would like to know what criteria are good to check during a consultation when choosing sunscreen. This is not a request for a review of a specific product or a personal account of skin issues, but rather an inquiry to summarize general skincare principles.

How should I interpret the SPF and PA ratings indicated on the product in the context of everyday life? I would like to know what criteria to use when checking the product and usage instructions, depending on whether I spend a lot of time indoors or outdoors, or if I sweat or come into contact with water. I am also curious about how to combine the product description with the activity environment to determine the amount and frequency of reapplication.

I would also like to confirm the order of use when applying makeup, easily overlooked areas like the eye area and neck, and cleansing methods during the consultation. Please advise on what information to record and provide during the appointment if stinging or redness occurs during use, and what to check before changing products. I understand that a decision tailored to an individual's skin condition must be made through consultation with a medical professional.
