Can you use the Cell Defense from Lancome while you still have some zits?

Earlier this year, I broke out a lot and now they almost gone but I have lots of acne scars. My sister had the same problem and she used the cell defense from lancome and now she has the most beautiful skin. But she used it when all of her acne was clear. I, on the other hand, still have some zits. But I HATE those scar so I wanna use the cell defense now. Have you ever tries cell defense for the same reason? Do you think it'll be ok if I start using it now? Thanks in advance!|||I think it's fine to use it and if anything remotely happens you can always just stop using it
