Hi, research has shown that all you need is sugar and lemon juice. First, get a bowl, add a table spoon of sugar and then add the lemon juice making sure not to add too much lemon because we dont want your face to burn! Mix it in a little then get a sponge, dip it in, and gentle dap the sponge on your scar. This method works as the lemon is a mild acid getting rid of the top layer of skin but not harming the underlayer of skin. The sugar is gritty so that will help get the skin layer off in a gentle way. After you've done this wash it off and add a moisturiser to soften the skin and calm it down a bit. Its cheap and easy to use! WELL... ITS CHEAPER THAT �39.99!
