Three Representatives of Cosmetic Peptides
Posted: Dec 18, 2017
In my previous article, we have explored the basics of cosmetic peptides as promising therapies for skin problems. In this article, we are going to discuss three cosmetic peptides respectively about their characteristics and beautifying benefits at the same time, namely acetyl hexapeptide-3, palmitoyl tetrapeptide-7, snap 8.
Acetyl hexapeptide-3 is a synthetic anti-aging cosmetic peptide derived from natural proteins. Just like many other biomolecules, it has a number of synonyms:
Argirelin Acetate (its trade name);
This peptide actually belongs to the neurotransmitter peptide category, which functions by inhibiting acetylcholine release through a variety of chemical interactions. Acetyl hexapeptide-3 has been proved to be very effective in reducing certain types of wrinkles.
The rational is: by binding to the SNARE-receptor thus blocking the production of neurotransmitter which then reduces facial muscle contraction, this peptide succeeds in decreasing wrinkle formation, especially around the forehead and eyes caused by repeated contraction of facial muscles.
Palmitoyl tetrapeptide-7 is another peptide of cosmetic benefits. It has been used in beauty products and cosmetics to reduce the cumulative amount of damage caused by inappropriate exposure to UV light, pollution, internal stress, and other pro-inflammatory factors. This distinguishes it from the above-mentioned acetyl hexapeptide-3.
The synonyms of palmitoyl tetrapeptide-7 includes:
Palmitoyl tetrapeptide-7 works by suppressing the production of excess interleukins, and in this way, inhibits unnecessary inappropriate inflammatory responses and glycation damage. It is used to counteract skin slackening and increase the firmness of the fragile skin area around eyes. So after reading this article, you may have a close look at your eye cream to see it contains the any palmitoyl tetrapeptide-7 ingredient.
Snap 8, also called Acetyl Glutamyl Heptapeptide-3, or Acetyl Octapeptide-1 (or -3), is a polypeptide scientifically and reasonably designed to be anti-wrinkle effective. It has a similar role to Areginine Essence and has become one of the most popular raw materials around the world for upscale anti-wrinkle cosmetics.
Compared with its alternative Botulinum Toxin, snap 8 is safer, cheaper and milder, both with the same wrinkle-formation mechanism but in a very different way.
Very similar to acetyl hexapeptide-3, snap 8 especially targets for reducing the depth of wrinkles on the face caused by frequent contraction of facial muscles, especially in the forehead and around the eyes. Being a mimic of the N-terminal end of SNAP-25, snap 8 competes with SNAP-25 for a position in the SNARE complex, thereby modulating its formation. If the SNARE complex is slightly destabilized, the vesicle cannot release neurotransmitters efficiently and therefore muscle contraction is attenuated, preventing the formation of lines and wrinkles.
