I've been increasingly worried about my skin texture lately, so please recommend some skincare products.

On Saturday, I attended a middle school classmate's wedding for the first time in a long while. I was so excited that I put a lot of effort into my makeup before heading out, but when I looked at the group photos later, I realized I was the only one who looked dull and lacked elasticity. I wondered if it was just the lighting, but seeing the smooth skin of my friends standing next to me suddenly made me feel upset. So, on my way home, I spent a long time thoroughly reading recommendation posts for popular skincare products on online communities. I thought I was diligent with my basic skincare, but as expected, the information from experts and skincare masters is different. Now, I desperately need recommendations for products that can solidify the foundation of my skin, going beyond just applying products. Perhaps because of the changing seasons, I'm really worried because dead skin cells are flaking and my makeup isn't applying well. Do any of you have any recommendations for skincare products that you have actually used and found to be of great help in restoring your skin condition? I would be truly grateful if you could share even the smallest tips. I'm curious to know how everyone is doing their home care these days.
