Suggest Remedy For Discolored Scars On Face And Legs

Hello, I'm Daisy and I'm 17. I want to know if there is anything I can do for discoloured marks, scars on my legs and face? I got them from spots, flea bites and razor nicks and I have had them for a very long time. I have used every product imaginable, lotions creams like bio oil, palmers scar lotion, aloe vera gel, vitamin e. Nothing helps fade them. They are causing me a huge amount of distress, I get very upset most of the time. I won't leave the house if they are on show. I don't go out in summer, I can't go swimming or to the beach. I wear makeup all the time. They are making me very depressed and have done for ages. Please help.
