If lip peeling persists, should I seek medical attention before moisturizing?

I have a question regarding lip care during the changing seasons. If my lips repeatedly become dry and develop thin, flaky skin, at what point should I seek medical attention? It is easy to dismiss this by saying that lips are naturally prone to dryness, but I would like to know if this is simply a case of insufficient moisture or if further examination is necessary.
I think there is a difference between cases where simply applying lip balm more frequently is sufficient and cases where you need to examine the products you are using first. If I experience stinging or discomfort when applying moisturizing products, I should mention that during the consultation, right? Rather than receiving recommendations for specific products, I would like to know what information I should check regarding my current condition.
Should I explain cases where dead skin cells are visible only in the center of the lips differently from cases where the lip border becomes red or rough? If I lump everything, including discomfort at the corners of the mouth, under the single term "dryness," it seems difficult to convey the situation accurately. Would it be helpful if I described the location of the discomfort, the duration, and whether there is stinging or itching?
I am wondering if it is necessary to organize the products that come into contact with my mouth on a daily basis, even though I rarely use makeup products because I am a man. Should I mention not only lip balm but also toothpaste, mouthwash, and products used after shaving? Rather than predetermining the cause, I would like to prepare by knowing the scope required for treatment.
When dead skin cells appear, it can be tempting to pick at or remove them with your hands, so I should probably let you know if I have such habits, right? I am curious if lifestyle habits, such as whether I frequently lick my lips or spend a lot of time breathing through my mouth, are also checked during the consultation. I would like to hear an explanation as to whether this is simply a matter of changing a single product or if lifestyle management needs to be addressed as well.
If I receive medical treatment, I would also like to know what criteria I should use to monitor my progress. I suspect that the timeline for the skin becoming smooth on the surface may differ from the time it takes for the stinging or tightness to disappear. Could you please provide specific guidance on the duration of observation while continuing to moisturize and the criteria for when I should inquire again?
I would like to know if I need to bring the products I am currently using, or if photos of the product names and ingredient lists would suffice. If I have been using any medication previously, would it suffice to just let them know the name and duration of use? I would also like to ask if I can explain my condition using photos I have taken of my usual state, even if I visit on a day when my symptoms have subsided.
I would like to ask if I can receive treatment for recurring lip dryness and peeling at the Maypure Magok branch. It is easy to think of specific care items for facial skin, but I'm not sure where to inquire about lips, haha. I am not thinking about procedures right away; I would like to have my skin condition assessed first and know the necessary direction for care.
