My skin has been damaged a lot due to frequent overtime work.

Hello. I've been working overtime every day lately due to a project deadline, and my complexion has gotten really bad. Yesterday, on my way home from work, I was shocked when I saw myself in the elevator mirror. Seeing my skin looking dull, to the point of dullness, I knew I had to do something about it. So, I'm writing this post to get some skincare recommendations from the community. Honestly, I'm busy getting ready for work in the mornings and exhausted in the evenings, so I don't think a complex routine would be feasible. Could you recommend a skincare product that I can add to my basic routine or apply lightly before bed? A face pack would be great, but something like a highly concentrated ampoule would also be good. I'm curious about how you all maintain your skin condition in your busy daily lives. For someone like me who's short on time, if you could recommend a simple yet effective skincare product, I'd really appreciate it. Do you have any tips of your own?
