What is the condition of your scar? I stopped messaging at about three months. At that time my scar was hardly noticeable. It really depends on the condition of the scar. Now 11 years later it is about impossible to tell that I had surgery ... zero contraction and no visable scar except if a person really looked closely.
Are you using a hand lotion to keep the scar moist. That is really important, in my opinion, to keep friction and abrasion at lowest level. I used Aveeno lotion during the entire healing process and the outcome couldn't have been better.
