I had to get stitches on my face, 5 on the cheek and 3 above lips. (photo)

Just wanted to know how to get rid of these scars completely. I met with an accident 2 weeks back and just got my stitches removed a day past. It seem that stitches have led to some scars over my cheek and above lips as in the pic. The other part of the cheek (with whitish spots) are yet to attain the natural color of the skin. Do i need to take some prescription from a skin specialist or these scars will automatically be healed. Please guide me for this.
