Best Ointment for Scarring After Mole Removal?

I am 23 years old, and I had 2 moles cut from my face and stitched back up last week. The stitches have already been removed, and the plastic surgeon gave me "Pro-Heal Serum Advanced" from iS Clinical to use for scar prevention, but I have read that Aquaphor works as good as any scar ointment. I told the nurses that I have been using Aquaphor and they insisted I stopped using Aquaphor and switched to the Pro-Heal. What should I use, and for how long should I apply it? Thanks!
