If the roughness extends not only to the back of the hand but also to the sides of the fingers, is there anything else to check besides moisturizing?

I am writing to inquire if I can receive treatment for hand skin concerns during the changing seasons. If the backs of my hands feel rough, extending beyond just slightly dryness to the sides of my fingers and around the knuckles, are there any other areas I should check besides applying more moisturizer? I would like to know first if hand skin treatments are available at the Gimpo Janggi branch.
Since you wash your hands frequently and touch various objects, it might be difficult to notice exactly when your skin has changed. Instead of simply describing it as dry, I should differentiate by mentioning whether you experience stinging, itching, or redness, right? Would it be helpful to also specify exactly which part of your hand—the back, palm, or between your fingers—feels uncomfortable?
I am wondering if it is necessary information for the consultation whether both hands are in a similar condition or if one side is more concerning. I would also like to explain if I engage in work that requires frequent hand use or if my hands are exposed to water for extended periods. Rather than attributing lifestyle habits to a single cause, I would like to organize and convey details that will be helpful for the diagnosis.
I'm not sure if I should always choose a thicker product when selecting a hand cream. I think the feeling immediately after application might differ from the level of comfort after some time has passed. I was wondering if letting me know what products I currently use, such as hand sanitizer and gloves, would be helpful in providing guidance on hand care.
I would also like to confirm if it is safe to rub my hands or start with exfoliation just because there is surface flaking. I think the priority might differ if dryness and irritation are present together. Please advise if I should schedule a consultation to assess my skin condition first, rather than focusing on cosmetic care.
I would like to hear about home care methods based on practical guidelines that can be followed in daily life. Could you explain this by breaking it down into situations such as washing hands, the time spent washing hands, and using gloves? Since I cannot avoid using my hands entirely, I would like to know which areas I should adjust first. Rather than being told to change everything at once, I would prefer to know the priorities.
I am also curious about what changes I should look for and how I should monitor the progress after the consultation. Should I separately record if the surface looks smooth or if the stinging sensation has lessened? If the condition improves but then becomes uncomfortable again, I would like to know how long I should observe the process before a follow-up visit, and if this information can be provided during the consultation.
I would appreciate it if you could let me know if I can receive treatment for these hand skin concerns at the Maypure Gimpo Janggi branch. It seems easy to immediately worry about even the smallest changes on the face, yet just think of solving hand issues with hand cream, haha. If anyone has consulted with similar concerns, I would also like to know what explanations or lifestyle management guidance were helpful.
