Neosporin is good for next time to put on right away so it does not get infected and will help fade the scar. Bio oil,vitamin e oil and cocoa butter stick are all things that help fade scars. I had a breast reduction and put cocoa butter on every day for a time period after and it faded my scars to a normal skin color. It is true that the sun will cause they scar to come out more. It will take time. It will get better. Take care.
