These days, I'm worried about how often I should use a sheet mask depending on my skin condition.

Last night, I met a friend at a cafe and was shocked when I saw my face reflected in the bathroom mirror. Maybe it was because of the seasonal change, but my skin was especially flaky and all my painstaking makeup was flaking off. Normally, I'd just put on a sheet mask whenever I remembered, but now I'm thinking I need to start practicing a more systematic home care routine. How do you all set your own mask pack frequency? Some people say one sheet mask a day is good, while others say it can actually irritate the skin, which is confusing. My skin is a bit sensitive and prone to dryness. What's the most effective way to set a sheet mask frequency in this case? I'm also worried that if I use it too often, it might weaken my skin barrier. If you have any tips on how to optimally use sheet masks for clearer skin, could you share them with me? I'm also curious how many times a week other people typically use them.
