My skin looks dull, probably because of the large temperature difference between day and night. Please recommend some home skincare products you're using these days.

Lately, whenever I wash my face and look in the mirror in the morning, I can really feel that my skin isn't what it used to be. To be honest, I used to use being busy as an excuse and settled for just visiting a salon occasionally. But it suddenly occurred to me that home care truly involves putting in a little bit of effort every day. I want to start again step-by-step, beginning with basics like face masks and peeling gels, but there are so many different types that it's hard to choose. It's a huge concern, especially in this weather with large temperature fluctuations; white flakes of dead skin appear, causing my carefully applied makeup to cake immediately. I feel a desperate need for effective home care that can cultivate a smooth texture without irritation. I've been trying various things on my own, but I think vivid advice from experienced people would be the most helpful. What kind of home care do you usually do to soothe your tired skin after work? If you have any top recommendations or skincare habits, please share just one of each.
