Will microneedling be my best option? If not, any suggestions? (Photo)

2 years ago I had a raised white mole removed via kyrotherapy. I noticed about a year ago that it was growing back so I did another session of kyrotherapy. A few months ago I noticed there’s a raised place where the mole used to be. I went to a laser clinic and they told me that it was a scar. I need to know the best option for treatment! I start modeling in less than 4 months!
