Drink a lot of water.

Lemon Juice.

Aloe Vera Gel. (You have to buy this at the store, but you can just tell your parents your using it for pimples and moisturizer, because it's also known to help with that.)

Squeeze lemon juice onto a cotton ball, gently go over your scars, do it every day and they'll fade away

there isn't really a way to get rid of scars. try using makeup such as base to cover it up

I have a scare too but try ontmint
