I would like to inquire about the frequency of using mask packs for seasonal skin care.

Today, I met up with some friends for the first time in a while and had a pleasant chat. I was on my way back from a long-awaited visit. I happened to catch a glimpse of myself in the elevator mirror. Perhaps because of the bright lighting, my skin looked more flaky and lacking elasticity than usual. I figured it was time for some serious skincare, so as soon as I got home, I took out a sheet mask I'd been keeping in my drawer and applied it. But then I suddenly wondered if it would be more effective to stick to a set routine, rather than just using it occasionally. People around me say one sheet mask a day is good, but I'm worried it might be too irritating for my skin at my age. How do you usually manage your sheet mask frequency? My skin is quite thin, so using it every day might be a bit much. Dryness worsens during the changing seasons. If you have any tips on how to use sheet masks or special moisturizing tips, I'd be grateful. I hope you all stay healthy during this changing season and maintain beautiful skin.
