I'm surprised by my unfamiliar reflection in the mirror, so I'm looking into skincare products.

A few days ago, I went on an outing with my family. We took pictures in the warm sunlight and were so happy, but when I got home and opened my photo album, I felt a little depressed. Zooming in on my face in bright natural light, I noticed that previously invisible blemishes were clearly visible around my cheekbones and eyes. I used to pride myself on applying sunscreen, but now that I'm in my 30s, my skin barrier has weakened, and the UV rays seem to be lingering, which is frustrating. So, I'm diligently gathering information to try a serious skincare routine. With so many products on the market, it's hard to know which ingredients are right for me. Some people recommend high-potency vitamins, while others emphasize consistent use of gentle skincare products. Going to a dermatologist is a bit of a time and expense burden, so I'm trying to change my daily routine at home. Do you know of any skincare products you've tried that absorb without leaving a sticky residue and brighten my skin tone? I would really appreciate it if you could share your honest recommendations or management know-how.
