Dear forum members,
I am considering purchasing the Potent-C Power Serum by Peter Thomas Roth. It contains Tetra C, vitamin E and ferulic acid. The only drawback seems to be the fact that I have read online that Tetra C serums can only work well when they are in a formulation WITHOUT water, and this seems to be a formulation WITH water. LAA irritates my skin and my skin doesn't agree with silicones either, so at a first glance this seemed to be a pretty good product, until I read about the fact that Tetra C may not work well in water. Any thoughts?
Best,
JE |

Hi,
Tetra C will still work in oil-in-water formulations such as this Peter T Roth. It is incredibly stable. It's not pH dependent therefore you won't find it irritating. |
