How to remove a white cold sore scar? (Photo)

I have a white scar on my lip from a cold sore. It's very tiny, but the white scar is noticeable on my lip and making me very self-conscious. I've used vitamin E, Maderma, and scar treatment from Forces of Nature. I've considered a glycolic acid peel but read it could cause more harm. What is my best option? Thank you.
