Will my skin improve if I just get laser toning consistently?

I am looking into dermatological treatments because of freckles, blemishes, and my overall skin tone, and I have received a lot of recommendations for laser toning.

I heard that many office workers do it because it is relatively mild and does not significantly interfere with daily life.

But on the other hand, I'm conflicted because there are a lot of comments saying the effects appear very slowly and you have to get it done consistently, and there are also reviews saying you can't even see a difference after just a few sessions.

As the price becomes more burdensome with each round, I wonder if it is really worth the investment.
