Facial pigmentation, where the color remains uneven on the face

Lately, when I look in the mirror, I've noticed my skin looks uneven overall. It's not just a specific area that's darker, but there are patches of discoloration here and there on my face, giving me a dull, dull look. At first, I thought it was just a skin tone issue, but after researching, I found that many people also believe this is a sign of facial pigmentation.

After some research, I found that facial pigmentation has various causes and that the approach varies depending on the depth of the pigmentation. Some cases are managed, while others require repeated treatments to improve, making me feel uncertain about making a decision on my own. I'm curious about what approach is most realistic for widespread facial pigmentation like mine.

I don't want anything drastic, but I'm hoping for an overall improvement in my skin tone. Based on my current condition, I'm wondering if it's possible to manage my facial pigmentation, and what kind of plan would be best.
