Hi Guys
Just wondering if there is any difference in this two product lines. I've read that at one point they where together and than one of the guys walked away and came out with skinceuticals. I've also read that Skinceuticals C in better? From the looks of the ingredients they look pretty much the same to me.....

| When I first started Vit C about 2 months ago I didn't know which brand to go with and read about those two as well as others. I ended up with the skinceuticals C + E mainly because I read it helped prevent sun damage when applied under sunscreen. In terms of the Vit C component I am not sure I notice any changes.... But someone told me Vit C can take a year to work, it is not a quick fix. I'll be interested to see others replies! |

True: the gentleman who owns/created Skinceuticals was once a part of Cellex-C. He is the man who who conducted all of the studies (through Duke University) about the effects of l-ascorbic & ascorbic acid on the skin. He did not like the direction that Cellex-C was heading in, professionally, and thus ...started his own company, taking the paperwork/studies with him! Competition is good!
Both product lines are comparable, however Skinceuticals (and Canadian company Vivier) have a lower pH than that of Cellex-C. This reduces the "tingling" sensation that some experience, and may be more comfortable for those who have a more sensitive skin. Also, the lower pH allows more absorbsion by the skin.
Skinceuticals also has it's Primacy skincare division, which offers specific formulations (i.e. C+E Serum) that the competition does not. Skinceuticals/Primacy also has a Serum 20, which is the highest amount of vit. C that the skin can absorb. Cellex-C's Advanced-C Serum is 17.5%. |

| I would go with SC over Cellex-C actually. I get the impression that the Cellex-C oxidises quicker than the SC one. It could be just the one bottle that I have being a bit funny but I certainly didn't have this happen so quick with the Vivier or the SC. |

| I find that both Cellex-C and Skinceuticals oxidize and turn orange really quickly. Their vitamin C formula is not stable, and the serum loses its effectiveness after 1-2 months as it oxidizes. Vivier makes a much better vitamin C product. |

I have a question.. What do you mean that it's Stable? as you where saying about Cellex-c and SC. |

The SC that I had before didn't turn orange as fast as the Cellex-C. You're right about the Vivier though - it has retained its color the longest. Mind you, on the Cellex-C bottle it says that darkening is normal and it does not significantly effect the concentration of the product. Not sure what to make of that.
Skinprofusion - vitamin C is not a stable ingredient and it oxidises thus losing its effectiveness. What you want to do is look for a formulation that is stable and oxidises slower than other formulations. |
