Hi Linda,
It has been 6 months since my neck dissection. I purchased vitamin E oil and applied it every night. My scar has healed well and looks good. Neosporin is also a good option but I didn't want to keep the scar too moist and Neosporin tended to keep my scar more moist than I wanted it. I hope that makes sense. I struggle with Lymphedema so I have to wear compressions on my neck and chin at night so the vitamin E oil seemed to work with with my compression bandage. If you don't have to wear compression bandages, I think Neosporin would be a great option to reduce the visible scarring. Good luck to you!
