Reviewed and rejected: Striking With Smartpeptides
Perhaps it's because they're just so goddamn smart.
Well, let's see. Striking Rejuvenating Eye Creme has but one peptide, hexapeptide-21. The only literature I could find about this was on the Helix website. It is supposed to stimulate collagen production and fibroblast cells. The only research cited does not refer to whether hexapeptide-21 does what it says, but only that it was shown to be "non-cytotoxic, non-mutagenic, non-irritating and non-sensitizing".
The peptide in Striking Restorative Moisture Creme looks more promising. Palmitoyl hexapeptide-14. A 12-week study showed that "palmitoyl hexapeptide-14 is equivalent to RENOVA® (0.05% tretinoin) in reducing the appearance of fine lines and wrinkles with none of the irritation and redness caused by retinoid based products".
Even if these peptides were to undergo more rigorous testing and be shown to be so smart that they could beat Big Blue at chess, I would still hesitate to use these potions. These lonely peptides seem to be adrift in a sea of things that are mostly there to bulk up: silicones, copolymers, emollients and emulsifiers (all those ceteareths), and film-forming acrylates.
