Getting rid of acne scars

Having unwanted zits on my face used to be a high school nightmare. But last week, a big pimple grew on my chin and to my dismay it grew bigger! Ugh, just when I thought I won’t be getting any more of those high school pimples. Now it’s healed but unfortunately a big ugly scar remains. Looking at it makes me think of acne scar removal treatment. Maybe I’ll just apply cocoa butter on it as others recommend this as a home remedy for removing scars.
