I'm so frustrated with my blemishes that I want to get a treatment for them. Is the satisfaction level really high?

The sun is getting stronger these days, and the blemishes slowly popping up on my face are really making me sigh, so I'm looking into blemish treatments. Is the satisfaction rate really that high? I hear that freckles and age spots disappear completely after just one session, but some people say that for melasma or light pigmentation, you need to get treatments like toning dozens of times. It really scares me.

The cost is one thing, but it could also make your skin more sensitive. Is there anyone among you who has had blemish treatments who was satisfied enough to feel it was truly worth the money?

How is everyone managing their blemishes? I'm really debating whether I should get a procedure. I'm a "blemish treatment nomad" looking for the perfect result, so I'd like to get some help.
