Will the laser treatment be super effective for the small brown blemishes and freckles under my cheekbones? ㅠㅠ

When I look closely in the mirror under bright lights, I can see tiny, brown spots resembling melasma or freckles popping up on my cheeks and under my cheekbones. On top of that, the texture of my pores is slightly visible vertically, so my complexion doesn't look clear at all; it looks incredibly dull. I'm seriously going crazy with stress over this. I heard that home care isn't effective for pigmentation that has already deepened, so I'm researching a lot about going to a dermatologist to get the Clarity laser for blemishes! If I get a package of 5 or 10 sessions regularly, will the melasma and freckles completely fade and my face regain its clear and transparent look? I'm also curious if the laser is really painful and feels intensely hot when it's fired. I'm worried that a lot of scabs will form and look messy for a long time. Please, those of you who have received laser treatment to remove pigmentation, share some real-life tips!
