Are there any management tips when I suddenly feel unfamiliar with my reflection in the mirror?

Hello! Lately, I've been so busy with work that I've barely had time to take care of myself. Today, I went to a cozy cafe with a friend, and unfortunately, the lighting was incredibly bright. When I looked at my face in the bathroom mirror, I noticed it looked much duller and less elastic than usual, which really upset me. I realized I need my own skincare routine, so I came here to get some skincare tips from you. I've been trying to apply face masks and apply basic skincare products diligently, but I haven't seen any noticeable changes, which is worrying me. Because of the dryness, my makeup tends to look flaky and lifeless, so I feel a little less confident whenever I go out. Could you share one small skincare tip you use in your daily life? Rather than resorting to expensive treatments, I'm curious about consistent at-home habits or cost-effective products. With the changing seasons, I imagine many of you have skin concerns. Please share some skincare tips that have proven effective. How do you recover from poor skin condition?
