How can I remove the patchy blemishes that have appeared near my cheekbones?

At some point, dark spots started appearing one by one around my cheekbones and under my eyes, and now my entire face looks patchy and dull, so I just sigh every time I look in the mirror.

I never skip applying sunscreen whenever I go out and consistently apply brightening essence, but far from fading, the pigmentation seems to be getting sharper day by day. Even when I try to cover it up by applying a thin layer of concealer, the distinctive dark shadows still show through, making my complexion always look dull and tired.

Since there are so many different types of pigment lasers, I heard that the equipment used varies completely depending on whether my blemishes are melasma, freckles, or age spots. I am worried that if the intensity is adjusted incorrectly, the pigments might get stimulated and actually darken, causing a side effect. I would like to hear your experiences regarding how many treatment sessions are typically required to see noticeable fading of the blemishes.
