I have dark spots and freckles on my face. Is the Clarity blemish laser painful? ㅠㅠ

Even though I applied sunscreen quite meticulously, spending a lot of time outdoors has caused dark spots and freckles to pop up under my eyes and around my cheekbones. My complexion looks so dull overall, and it’s incredibly stressful because they don't even come off when I cover them with makeup. I’m currently looking into the Clarity laser treatment for blemishes, which is said to be a surefire way to correct skin tone and remove pigmentation! To get rid of the freckles completely, how often should I visit a dermatologist regularly for effective results? My skin is a bit sensitive, so I’m really curious if there are any side effects like scabs forming or prolonged redness after the laser treatment. If there are any seniors who have consistently received laser treatments to get rid of blemishes, please share your tips on whether it really works!
