Dear Skin Biology,

I've read that using copper peptides and vitamin c at the same time will cause free radicals to form. I am wondering if any of the other products I use contain any ascorbic acid in them. Can you please tell me if any of the following ingredients contain vitamin c (ascorbic acid):

peppermint oil
rosemary leaf oil
rosemary extract
comfrey root extract
sunflower oil
castor oil
candlilla wax
carnauba wax

?

Would the above ingredients be all right to use with CP serum? Or do they contain ascorbic acid?

Thank you!

In theory, there may be a problem with vitamin C and SRCPs. But many women have told me that they use both together and have beautiful skin. Also, no one has ever reported a problem with using both together.

Scientific theories are not always right.

So all of your oils and waxes should be OK.

Thank you for replying Dr. Pickart.

But I was wondering how much ascorbic acid is in the ingredients I have listed in the post above. Is there a lot of ascorbic acid in them?
