Try using over-the-counter hydrocolloidal/alcohol-based creams. You may also try putting petroleum jelly on the scar. It is not completely clear to me what this will do for you, however.

Maybe you could put a small patch on top of it?  Just check out your local library and see if they have any books on patchwork and quilting.

I think scar-removal is currently only available in cosmetic surgery.

Isn't there anything I can do at home to make it less visible?
