A skin care method that suddenly came to mind under bright lights

I finished work late and looked in the elevator mirror after work. I was shocked by how dark and rough my complexion looked under the yellow light. Normally, I just washed my face with soap and applied whatever cream I could find, but now I'm starting to think I need to develop a truly systematic skincare plan. My friends are already using eye creams and functional ampoules, but I'm a little worried that I'm lagging behind. Honestly, even when I try to research skincare routines on my own, the terminology is so unfamiliar and complex that I have no idea where to start. Rather than blindly buying expensive cosmetics, I want to create a skincare routine that focuses on the basics, tailored to my skin type. What's a good approach? Do you have any tips or recommendations for essential products that even someone as lazy as me can easily implement every day? I'd love to hear your valuable advice.
