A customer emailed a good question:
Can you please clear something up for me? I had read that you should not mix copper and vitamin c, because they cancel each other out. What are your thoughts?
Thank you for contacting us, and for your question. You're correct that ordinarily substantial amounts of copper and vitamin c should not be mixed together since they can cancel out each others' effects.
Basically, copper can oxidize the ascorbic acid and cause it to break down too rapidly, which of course diminishing the benefits of such vitamin c ingredients.
You would not want to apply an ascorbic acid product like our Reviv-C 36% Vitamin C Serum either immediately before, or after, applying Copper Peptide Healing Serum.
We recommend using one of those products in the morning, and the other one at bedtime. At the least, we recommend waiting at least one hour before applying such an ascorbic acid product on top of copper, and using a toner to balance pH before applying it.
