Every time I look in the mirror, I'm concerned about facial pigmentation. Could you give me some advice?

I enjoy exercising and spending a lot of time outdoors, but one day, when I looked in the mirror, my complexion suddenly changed. It seems like I've been out and about without applying sunscreen, and I've noticed darkened pigmentation around my cheekbones. Things I hadn't noticed before are starting to become noticeable. At first, I thought it was just fatigue, but after washing my face, I looked closely and saw that I definitely had more blemishes, which was disappointing. Every morning, when I shave, I see pigmentation in the mirror. These marks make my overall appearance look dull and even unkempt. I desperately want to maintain clear skin, but it's hard to know which products are best for men. I've tried searching for functional essences and creams, but the sheer variety makes choosing difficult. I'm curious about how you specifically addressed the pigmentation I've developed from being outdoors like you. Is a dermatological procedure the most effective treatment, or is it possible to improve it with consistent home care? If you have any tips or products that are gentle on men's skin, please let me know. How do you typically manage your skin?
