Are there any tips for managing rough skin during the changing seasons?

I met up with some friends from high school after a long time, and they were all amazed at how clear and healthy their skin looked. Under the cafe bathroom lights, I looked so dull and tired. Back home, I stared in the mirror for a long time, lost in thought. My skin used to recover quickly with just a simple toner, but now I'm starting to feel it's not quite the same. I asked people around me, but no one had any secrets. So, I'm posting this because I want to share my skincare tips with the experts on this forum. Perhaps it's because my skin is getting drier these days, but even layering on basic products doesn't solve the problem, and it's frustrating. Is there anyone who would like to share their nightly routine or any cost-effective skincare tips? Even small daily habits would be helpful in restoring skin vitality. I'm curious to know how you guys maintain elasticity these days. Do you have any skincare tips you'd like to recommend?
