Peptides - The Good, The Bad And The Disappointing

Well actually, it's mainly disappointing!

Peptides That Inhibit Neurotransmitters

Neurotransmitters are things that make your muscles work when your brain tells them to. We're familiar with Botox and it's properties - Botox injections block the release of neurotransmitters to, in effect, paralyze the muscles. Thus, after Botox injections between your eyebrows, when your brain tells your eyebrows to squint, nothing happens.

There are anti wrinkle products being marketed to take advantage of the fact that everyone knows and accepts that Botox works. These anti wrinkle creams contain peptides, but do they really work like Botox?

Peptides are proteins consisting of small chain amino acids. Argireline is the name given to a certain peptide (a lot easier to say than acetyl-hexapeptide-3) that slows down the release of neurotransmitters. In wrinkle cream containing up to 10% Argireline, laboratory tests show that it provides some benefit towards the appearance of having younger looking skin. However, the jury is out about whether the peptides can actually go into the skin and through to the muscle level, which they would need to do to replicate Botox. Some have suggested that it's the product's accompanying moisturizing ingredients that reduce wrinkles by hydrating the skin. Also, if the product worked like it claimed, any muscles that came in contact with the cream (face, neck, finger tips) should cease working - but they don't.

Peptides That Stimulate Collagen

Another peptide (palmitoyl-pentapeptide-3, also called Pal-KTTKS or Matrixyl) is reported to encourage the manufacture of collagen and other proteins that are found in the skin's dermal layer. Sounds promising, but how does it compare with Botox?

Well, tests have been conducted. Unfortunately, it didn't do any better than the plain moisturizer it was being compared against.

Peptides For Stabilizing Copper

Copper plays a vital role in living organisms. For us, collagen and elastin creation rely on the presence of copper. In theory, peptides can be used to stabilize copper, transporting the element to locations in the skin to improve the appearance of wrinkles. In practice, trial tests on people have shown only minimal benefits.
