I met up with friends after a long time and I feel like I'm the only one looking older, so I'm looking for some skincare tips.

Hello. I met up with some high school friends this weekend, and while everyone else was taking such good care of their skin, mine looked particularly dull. I thought it might be the lighting, but when I looked in the bathroom mirror, I could definitely see that my pores were larger and my skin texture was rougher than before. So, I'm thinking about taking more serious care of my skin now. Do you have any tips for skin care? Honestly, I've been just using an all-in-one lotion, but I think it's time to start building a solid foundation. Could you share any special products you use after washing your face, or any skin care tips that are safe for men? I'm wondering if frequent face packs might help, and I'm also not sure if diet has a big impact. Could you share some skin care tips that I can easily incorporate into my daily routine? Even the smallest advice would be incredibly helpful, so please feel free to share.
