I'm so stressed out because of the patchy blemishes. Has anyone tried melasma treatment?

I get so stressed out because of the patchy blemishes on my cheekbones, even when I try to go out in the morning with just sunscreen. After looking online and reading reviews, it seems like the solution is to consistently get professional laser treatment for melasma before it gets darker.

I've heard that treating melasma by combining toning and pigmentation management makes your complexion clearer and evens out your skin tone, even without makeup... but I'm hesitant to pay for it because I'm worried it might make my skin sensitive or irritate it. I also can't overlook the concern that I might get treatment only to find it hasn't faded and remains the same. Did you actually see your pigmentation completely lighten after receiving melasma treatment at a dermatology clinic? And from which session of the package did you start seeing results?
