Re: using Copper-P serum and vitamin C cream together. a big no?

[ Edited ]

This is Isomer’s response to me about using Copper-P and their Vitamin C together:

Hello [Montana]

There is no problem in using the Vitamin C & Ferulic 15% Skin Brightening Concentrate with the Copper P Concentrate Serum.

The formulas are stable, so that you can mix/cocktail them.

I just purchased a Prai product that has C and copper together. I couldn't resist.

PRAI Potent-C Power Drops & Power Creme


 

 

 

Those products contain another very stable and copper-compatible form of vc called tetrahexyldecyl ascorbate (THD ascorbate). THDA is also an oil and is oil-soluble, which means it has been demonstrated to penetrate the skin deeper than other forms of vc. THDA is super stable and can remain that way for up to 18 months even when exposed to air and light. Concentrations as low as 1% THDA have been shown to be effective. The only problem with THDA is that it is expensive.
