My facial pigmentation is depressing...ㅠㅠ

When I woke up this morning, washed my face, and looked in the mirror, I suddenly noticed a change in my appearance. I used to hear a lot about my skin, but at some point, pigmentation began to appear around my eyes and cheekbones...

This really bothers me.

Sometimes I feel frustrated because I can't completely cover it up with makeup. I don't know if it's because the sun gets warmer with the changing seasons, or if it's just the accumulated fatigue.

I thought I was diligently applying sunscreen when I went out, but I'm determined not to ignore the pigmentation that's already forming on my face. Honestly, I don't have the time to get professional care, so I'm trying to stick to my home care routine. Seeing my dull complexion in the mirror can make me feel depressed, so I'm desperate to find an effective solution.

Do you have any special products or lifestyle habits you use to improve facial pigmentation? Do you have any effective treatment recommendations?
