Question) Will my skin tone really brighten if I get laser toning?

Lately, my skin looks dull overall and the tone is uneven, so I'm worried.

I feel like some blemishes have started to appear, so I am looking into laser toning. I am wondering if my skin tone will definitely brighten if I receive it consistently.

I also want to know if the effect is temporary or if it lasts. I would appreciate honest reviews from those with actual experience regarding the frequency, cycle, pain, and side effects. I am extremely curious.
