Stitches Created Two Wrinkles on my Forehead at Ages 6 and 8. I Have Had Them Since then - Am Now 52. How to Eliminate?

Emanating from the large protuberances on either side of forehead but one scar is higher than other. The wrinkles extend just shy of mid line, the scars are visible still but not prominant. Have always had wrinkles since accident, but they may be deeper now as skin loses some plumpness. I have no crows feet or other wrinkles on my face except one vertical line next to left eye brow (scowl line!). How can I eliminate the forehead lines/scars?
