3mm mole punch biopsy scar expectations

Im going in to have a couple moles removed one being on my neck and one being on my face along my smile lines the doctor said he would be using a 3mm punch biopsy and that it would leave a 3 mm scar now im fine with having a small scar on my neck but im hesitant about the one on my face. So what i would like to know is, will the scar that is there be extremely noticeable and is there anything i can do to minimize my chances of getting a scar. I dont want something worse than the mole on my face
