Management tips written under the cafe lights, shocked and in a hurry

Yesterday, I went to a well-lit cafe with a friend and looked in the bathroom mirror. I noticed my uneven skin tone and makeup buildup, which I hadn't noticed before. It really upset me. I was sure I was using my usual basic skincare routine, but I don't know why my skin suddenly looked so dull. Do you have any special skincare tips for the changing seasons? I've been getting less sleep lately, but I still use face masks regularly, but my skin still feels dry. The skincare tips you share have me wanting to try them one by one. I especially get white spots around my nose and chin, and even if I touch up my makeup, it looks even worse. I'd love to hear your secret skincare tips. Do you have any recommendations for routines or product combinations that really boost my skin condition?
