Hi! You can by scar vanishing cream for usually very cheap. Freckle removing cream works as well. If you need a quick solution try water proof foundation!
Try getting those swim suits with long sleeves, or if it’s on your legs, theres, I think, long ones for those too. Search for them on Amazon. Another way is to just use waterproof makeup and try to cover it up. A lot of people just use makeup to cover them
