I was shocked by how I looked in my wedding photos, so I'd like to ask for recommendations for skincare products.

Last weekend, a really close friend's wedding took place, so I dressed up for the first time in a while. I felt great, took lots of pictures, and had a great time. Later, when I looked at the pictures in our group chat, I couldn't help but wonder why my skin looked so dull. I wondered if it was the lighting, but I noticed that I looked particularly lifeless compared to my friends, so I spent a lot of time staring in the mirror. I think it's time to really take care of my skin, so I'd like to ask for recommendations for some good skincare products. I used to just wash my face and put on whatever I wanted, but now I want to start taking care of my skin step by step. Everyone around me has started skincare routines, but I don't have much information on them, so I'm looking for recommendations and trying them out step by step. Could you recommend a skincare product that's not too complicated but still provides good hydration and elasticity? Are there any products that are easy for beginners to use?
