Relastin with zinc and matrixyl 3000 claims to be the first cream to restore elastin
What does work, we are told, is zinc. What's more, the claim is backed by clinical trials and the website features lots of beaming dermatologists endorsing Relastin as a breakthrough.
In February 2007, a group of dermatologists convened in Florida to review the results of two studies on zinc and elastin (one trial was on mice and the other on 26 women between the ages of 37 and 60). Unfortunately, the derms didn't seem terribly convinced and concluded that "The data to support the initial research hypothesis regarding elastin increases appear to be lacking". In a paper summarizing the discussion it was documented that "panel members also noted that a more convincing mechanistic explanation for how the zinc formulation increases elastin production was needed."
Funnily enough, the author of the paper was Victor Narurkar MD. He, along with two other members of the Florida review panel, are amongst the beaming dermatologists on the Relastin web site. I wonder what changed their minds.
Still, if you buy a jar of Relastin, you won't be putting all your eggs in the zinc basket. There are antioxidants in the form of matrixyl 3000 (made by combing two peptides: palmitoyl oligopeptide and palmitoyl tetrapeptide-7), grape seed oil, green tea and oxido reductases (a free radical zapping enzyme), plus a stable form of vitamin C and phytonadione (vitamin K1).
And if you do fork out the $99, beware of a couple of potentially harmful preservatives, phenoxyethanol and chlorphenesin.
