Do you have any secret skin care tips of your own?

Today, I was working late because of a deadline, and on my way home, I was startled by the bright lights in the elevator. My face was reflected in the mirror. My eyes were dull, and my skin wasn't as elastic as it used to be. I suddenly felt sad. I used to make excuses about being busy with work, just slept with a quick dab of lotion on, and it seemed to be showing on my face.

I think I really need some systematic management now, so I'd like to get some recommendations for management products. It would be especially good if it was a product that office workers like me, who are short on time, could use easily at night.

Are there any skincare products you've actually used and found effective in restoring your skin condition that are so effective that they're worth the hassle? I used to hear compliments about my skin, but these days, looking in the mirror feels stressful. If you know of any skincare products that can help me regain my vitality, please let me know! How do you maintain your skin condition?
