I'm worried that the number of dark spots on my face is increasing.

I've been really worried about dark spots lately. It feels like little spots are appearing on my face, and they're becoming more and more noticeable, which is incredibly stressful. I usually use sunscreen, but they seem to get worse sometimes. I'm not sure what's a good way to manage them, so I'm curious. Should I get some kind of treatment at the hospital? Or are there any products or lifestyle habits I can consistently use at home? A gentle method would be especially helpful. If you've tried it yourself, please share any tips or reviews you've found effective.
