my son has some scarring on his hand and "couldn't decide" whether to fix it or not. After almost 10 years (he's an adult) he's finally gotten to the point where the scars are more flexible now. The cosmetic aspect (how good it looks) doesn't matter to him.
But if i had been in control of the situation, i would have pushed him to get the surgery. Life's tough enough without stupid scars making you stiffer.
good luck.
