It's safe.

It's not a matter of safety, it's a matter of if you don't want to be so red or not.

I agree with DRaGZ, completely safe. You might want to ease into the C though... say every second day to start off with. It can be a bit irritating at first. I would pop the C on in the morning as it will boost your sun protection.

Thanks! I heard somewhere that vitamin c serum is an antioxidant and bp is the opposite so the vitamin c serum would cancel out the effectiveness of the bp, is that true?

Also has anyone broken out from vitamin c serum?

I'd say that using both the Vitamin C serum and the BP together is a bad idea, ie. putting them on at the same time. I would cleanse and then use the BP at night and then cleanse and use the C in the morning with your sunscreen. This is what I do only I use a Retin-A at night instead.

I didn't break out with the Vitamin C but I did get a bit of redness to begin with.
