How to Prevent Scarring on a Cut on Baby's Face? (photo)

My 1 year old baby fell on the side of the bed which left a cut just above the right of the the lip. We took him to a child specialist who said that it doesn't require stiches or treatment. The cut is about 1 cm long. So we left the wound open and it has now healed but it seems likely to leave a scar. Is it possible since that since he is so young this wound will not leave a scar on him. Any reccommendations on what to do so that it doesnt actually leave a scar in future.
