Please recommend a skin care product that can help me look confident even in bright sunlight.

Hello. This weekend, I met up with some old high school friends for the first time in ages and went to a cafe with a beautiful outdoor terrace. The weather was beautiful, so we chatted happily. Then, I looked at myself in the bathroom mirror and, oh my goodness, why was my skin around my eyes so dull? Under the bright natural light, I could clearly see the dark spots that hadn't been visible before, and I was really upset. I've decided I need to settle on a proper skincare product and use it consistently. I used to think that just applying a basic skincare routine was enough, but I've definitely learned that skincare is essential as time goes by. With so many products on the market, it's hard to know which one to choose. Do you happen to use a skincare product that's gentle on the skin but leaves your complexion looking brighter with consistent use? I'd appreciate it if you could share your valuable experiences and advice.
