My skin looks so dull under office lighting, so I'm curious about some skin care tips.

Lately, with the increased workload at work, I've been working overtime a few times, and my reflection in the mirror has become incredibly unfamiliar. Yesterday, I looked in the bathroom mirror before leaving work, and I was shocked to see how dull my skin looked and how prominent my fine lines were under the bright fluorescent lights. I used to be able to glow with just a simple toner, but now it seems like it's really hard to maintain a vibrant complexion without special skincare tips. So last night, I quickly applied a face pack and tried to get a good night's sleep, but when I woke up this morning, my skin still felt dry. Do you have any skincare tips you use to maintain a clear complexion despite your busy schedule? I'm especially curious about how to maintain moisture in a dry environment like the office. Maybe it's because of the seasonal change, but I'm also experiencing more dead skin cells, and I'm having a hard time deciding what products to add. If you have any skincare tips of your own, even if they're just small habits, please share them with me. I hope everyone is taking good care of their skin during this seasonal change.
