I was looking in the mirror under bright lights and was shocked. Could you recommend some skincare products?

Yesterday, I dressed up for the first time in a while and went to a cafe with friends. The cafe lighting was so nice that I took a selfie, and I could tell my skin wasn't what it used to be. In my early 20s, I used to look vibrant even with just a little makeup on, but these days, my complexion looks dull and flaky. I think it's time to get some skincare recommendations and really focus on it. Makeup can only cover things up, and I really want to improve my skin condition. Could you recommend any skincare products you've found effective? Products that combat dryness or smooth skin texture would be especially great. Don't pass up recommendations, I'll definitely be waiting for your recommendations. I'm really curious about your skincare routines.
