I'm curious about the effectiveness of laser toning for freckles and blemishes.

I am looking into laser toning for freckles and blemishes, and I am curious about how effective it is.
I know that it is not a one-time procedure but requires multiple sessions, but

I can't really get a sense of how much it's actually fading.
I heard that melasma and blemishes tend to recur easily, so you have to manage them consistently.
I've seen a lot of reviews saying that laser toning brightens the skin tone, so I'm curious to know how effective it was for those of you who have tried it.
If you are concerned about freckles and blemishes, please share your reviews so I can take them into consideration.
