Greetings. Were any stitches used to close this wound after you had go the injury. For better appearance of the scar, fractional carbon dioxide laser if one of the options, along with application of some creams like hexilak silicone gel. However, it may be rather tough to completely eliminate an existing scar. Also, you must not get mentally worked up because of this.. hope this helps, see a qualified dermatologist near you. Or further queries may be sent on follow up messaging
