Can I use Ambi fade cream for oily skin all over my face?

I have acne scars on my face and some discoloration. I was wondering if I could put it all over my face and leave it in for 30 min and wash it off. Has anyone done this? I'm scared because I'm olive and it might fade my complextion

Any successful homeremedies? It actually lightens skin which is not good!
