The Power of Peptides

The Power of Peptides

We know what you’re thinking: What the heck is a peptide, and why should I care? The simplest explanation is that peptides are a short chain of amino acids, linked together by amide (peptide) bonds. Still don’t care? You should. Peptides are everywhere, most notably in skin care that focuses on reducing wrinkle depth, smoothing fine lines and diminishing expression lines.

Ahh, now we have your attention.

For this lesson in science and skincare, we turned to resident expert and licensed esthetician Jennifer Christie. According to Christie, there are three types of peptides that are found in most skin care.

1. Neurotransmitter-affecting peptide: these interfere with transmitting the signals that cause muscle contraction. Fewer contractions mean less noticeable wrinkles. Within this peptide group are two common types:

-acetyl hexapeptide-8 is responsible for the decrease in wrinkle depth.

-dipeptide diaminobutyroyl bevzylamide diacetate is known for quickly smoothing wrinkles around the eyes and diminishing expression lines.

2. Carrier peptides: these deliver important trace elements like copper, which is necessary for wound (blemish) healing.

3. Signal peptides: these are receptors that bind to signaling molecules, and initiate a specific action within the skin (like stimulating collagen production). There are a number of signal peptides.

-Palmitoyl pentapeptide-4

-Palmitoyl oligopeptide

-Myristoyl pentapeptide-8 (new)

-Myristoyl hexapeptide-4 (Matrixyl)

-Palmitoyl tripeptide-38 (new)

Seem like a lot to digest? We get it. You don’t have to understand everything about peptides. Just know that they work hard to strengthen and improve the appearance of aging skin. It’s a key ingredient to look for as you select the skin care that best suits your current needs.
