I'm worried about my skin becoming more flaky these days. How do you take care of it at home?

When I got home from work and looked in the mirror, I was shocked to see that my face looked puffy and lifeless today. Maybe it's because of the seasonal change, but my makeup didn't stick as well and I kept feeling irritated, which was frustrating. Yesterday, a friend I hadn't seen in a while noticed a subtle glow on her skin, so I asked her what her secret was. She said it was her consistent home care routine. I've been using the excuse of being tired to just wash my face and fall asleep, but I'm trying to wake up and make time for myself. I'm starting with sheet masks and slowly trying to establish a home care routine, but now that I'm getting started, I'm not sure which products are best. It's still a bit overwhelming to buy expensive equipment, but are there any cost-effective home care methods that I can see results in? I'm really curious about your regular skincare routines. Are there any small tips that even a lazy person like me can stick to every day?
