Will this scar ever go away?

[Flames.Fan]

I've had it since 5th grade, im not in second year university. It seems like its getting worse, i head something about benzoyl peroxide being bad for your skin ( i use proactiv).. What can i use to lighten this, if anything? I was debating trying ambi?

Have you tried Bio oil?

I would try ambi first. But be advised, you'll probably have to use it 2-3 times daily (as often as you can, imo) and even then, it will take a few months before it lightens enough. BUT - it will work if it's a darker pigment because it blocks melanin production. During this (and especially after) you'll want to protect that skin with sunscreen so it doesn't re-darken.
