Scars on my arm from an event in my life?

i have had 17 deep scars on my arm from over 3 months ago. what can i do too help them heal?|||Try some silicon strips for scarring - you should be able to buy them from your chemist.|||cocoa butter for scars and stretchmarks there is also something else but i don%26#039;t remember the name i know it starts with a d and you can buy it at walmart,i have a friend that used it and she swears by it,also these things wont completely take away your scars but it will make them fade so that way they aren%26#039;t as noticeable!! oh and i also heard that vitamin e is good for scars too
