Laser pain and the possibility of applying makeup after treatment for deepening blemishes on the cheekbones in the late 20s

Until my mid-20s, I often heard compliments about my skin, but now that I’m entering my late 20s and summer is approaching, I can definitely see blemishes on my cheekbones that weren't there before becoming darker. Even when I try to cover them with concealer, my makeup just gets thicker, and it wears off quickly when I sweat, so I think I need a fundamental treatment. I’ve never had a laser treatment at a dermatology clinic before, so I’m really scared about how painful it might be. Is it bearable if I apply anesthetic cream? Also, as a working professional, I have to go to work the very next day after the procedure, so I’m really curious if it’s possible to apply sunscreen or light cushion makeup the day after the treatment. Please let me know.
