Had a mole removed two days ago, the dressing was removed today and I'm concerned about the length of the incision (4cm long)?

I had a 9mm diameter mole removed for cosmetic reasons 2 days ago by a plastic surgeon. It seemed expensive ($500). He removed the dressing today and there is a very large wound (around 4cm long). I feel disfigured. My first question is can anyone recommend things that I can do to minimise scaring? Will it settle? My second question is has anyone had this procedure done before? Is it normal to have such a large incision for cosmetic mole removal? Thank you in advance.
