Dark spot corrector

Anyone know of any good dark spot correctors? Or a way to lighten my acne scars. All the prego acne has me looking like a Dalmatian and I'm really starting to feel self conscious about it. I haven't really taken any photos since I've found out I was pregnant because of all the acne. I really hate it  😣 and vitamin e oil just makes me breakout more, so please no oil remedies
