What kind of treatment should I get to improve my skin tone?

I'm worried because my skin tone feels dark overall these days.

On top of that, as areas resembling blemishes or light age spots increased, my skin became patchy and uneven in tone, which bothered me even more.

There are times when I wake up after getting enough sleep, but I am told that I look tired.

I've heard that procedures like Pico Toning and Laser Toning are good for improving skin tone. Which procedure would be the best in terms of satisfaction?

Will there be any other side effects after the procedure? Are there any good treatments for improving skin tone?
