I'm scared to look in the mirror these days. Do you have any tips for taking care of it?

Yesterday, I was working overtime at work and looked in the bathroom mirror, and I was truly shocked. Under the fluorescent lights, my skin's unevenness and dullness, which I usually don't notice, were so clearly visible. It didn't look bad in the morning, but as time went by, my makeup came off and I looked messy, which was frustrating. Maybe it's because of the seasonal change, but no matter how much I moisturize, my skin feels dry quickly. Any tips on how to manage this? I'm sure many of you are struggling with dryness like I am, and I'm curious if you all take special care of your skin during your basic skincare routine. I try using face masks and layering essences, but I feel like I'm missing out on some really important skincare tips. Could you share some of your own skincare tips that have proven effective before bed or before applying makeup? Could you give me some advice on how others maintain their skin in this weather?
