Jeanne asks…Which peptides in face creams are most effective in communicating with facial muscles to cause shortening of them and therefore firming the face?
The Right Brain responds:
According to at least one study, acetyhlexapeptide-8 is capable of reducing wrinkles associated with facial muscles.
How peptides work
This peptide allegedly works similarly to botulintoxin, aka Botox (™), by inhibiting what is known as the SNARE complex which results in reduced muscle contractions. But unlike Botox (™), this peptide does not irreversibly destroy a key protein – its effect is temporary. Acetyhlexapeptide-8 is also supposedly able to relax the collagen and elastin matrix by altering calcium ion uptake.
The Beauty Brains bottom line
We’re skeptical because we don’t know the type and concentration of acetyhlexapeptide-8 used in any given product. Still, there seems to be at least some scientific basis for using this peptide to fight facial wrinkles.
