the best way to keep a scare from darkening is to stay out of the sun and if you do go out put sunscreen on the scar. also try scar zone twice a day or anything to the sort that has a silicone base.
Try using Bio-Oil or Cocoa butter, they work for scars and stretch marks to help smoothen the skin to help them fade.


A few other things you can try are- olive oil, wheat germ oil, vitamin e (cream/lotion/oil).


Try circular motions when applying this stuff too.
you cannot.
I have a scar on my face too. One of the things I used was a product called Mederma. You can get it in the healthcare section of Walmart. Its safe to use on the face and it make you break out (that was a problem with me) It is a little pricey but you only need a small tube and I think if its your face a little more money is worth it.
