Apologies in advance I have searched for the topic, but must be doing something wrong, as couldn't find it.
I have 3 bottles of different vitamin c that is browni orange, and just wondered is the only thing I can do chuck it 
One of them did come like that but the others have turned  and when I tried one I looked like fake tan gone wrong 
So thanks in advance for your advice  |

| I don't think the serum is much use if it's turned that brown - a little bit of an orangey colour should still be ok. If you got a brand new one that is brown, you should be able to return it though. |

If it's brown (not yellowish) - it's oxidized and pretty much useless. I am not sure, but I think I read somewhere that in that state it can actually be demaging to your skin (don't quote me on this, though).
I'd toss it!

Your right about the damage rubby. Any product that has oxidized will cause free radicals, and can potentially cause more harm than good. Better to just toss them!  |

I've heard this about oxidized C before, too. Also, on Tangal's post about C there's a line:
"Vitamin C oxidizes easily. Oxidized Vit C applied to the skin can increase Free Radical formation on the skin, creating oxidative damage on the skin surface."
Can anyone explain why this is the case? Isn't vitamin C an antioxidant because it has the ability to donate electrons without becoming a free radical itself? So wouldn't a bottle full of oxidized C just mean the C has done its job in the bottle and not in your skin? And wouldn't that oxidized C in the bottle just be useless -- but not harmful? |

RMB your questions made me think about something that I saw a while back and never got the chance to read. I found the article again and took a quick look. No comment since I really need to read it thoroughly first but here it is if you are looking for some reading on the topic. It is by Sheldon R. Pinnell so I imagine that it would be pretty reliable!

| How do you know if your vitamin c serum has oxidized? I noticed that the vit c from my Skinceuticals c+e ferulic & my candessence were both clear. However, I just received my ISC super serum & it's orange? Does this mean that it's oxidized & I should exchange it? |

The different serums do all start off as slightly different colours, I think if the super serum is a pale orangey colour it should still be good (although someone who knows that particular one better may chip in here and disagree). If it's a really deep orange though then I think it could be almost oxidised so you might want to call the company you got it from to check if they'll exchange it for you. |

| felinehhy I had read the same thing. As a C serum oxidizes it's pH increases. |

| one way to check if the Vit C is there or not, you can apply it to half cut apple and if it turned to brown, then that vit C has gone. |

Thank you fishzebby for your suggestion. I will try this tonight. I read in another thread that the vit c is usually a clear/pale yellow. But, for some reason the ISC super serum is suppose to still be ok if it is orange in color. My batch seems to be a deep orange. I will try your experiment tonight. I hope I still have some apples at home?! |
