The best type of scar covering that i've used was Mederma. I sliced my leg open on an apholestry staple behind a couch, and have been self-conscious about it for a few years. It had faded into a pink scar, but after using the stuff, it faded pretty decently. Also, if your going to the beach, and your self-conscious about letting your family see (understandable), than use a non water soluable light foundation (that blends with your skin). Mederma is quite expensive (20 bucks or so)...but as far as i can tell, it worked
, otherwise if your just worried about the quick fix, foundation would be my safest bet.
