I'm curious about mole laser treatment.

Hello, I am leaving a message because I am curious about laser treatment for spots and acne scars during this event. Over time, I looked in the mirror and noticed that there are a lot of blemishes on my face. I tried to ignore them, but I still want to take care of them, so I am looking into it. Will laser treatment for skin blemishes, acne scars, and pigmentation spots completely remove them? Also, I am curious about how long it takes for the wounds to heal. Lastly, since there are many spots, I would like to know an approximate number.
