Skin pigmentation. What's best?

As I get older, my skin is really bothering me. My skin pigmentation is really bad.

I guess it's because I haven't taken care of my skin since I was young, so it's a real mess.

Now, I'm trying various things to solve this problem...

Which one would be better?

I don't know whether skin treatment or cosmetics would be better.

Why is there nothing I like about my skin?

Freckles and skin pigmentation. It's getting worse and worse, so I'm stressed out.

If there's anything I can do consistently at home, please recommend it.
