The science of skincare. Some of us have no interest in the way an ingredient works, as long as it does. And that’s fine. After all, results are the bottom line. As long as the buzz is positive, we’ll try it. Others, on the other hand, have a vested interest in exactly what products do for your skin. Both groups have probably heard the word peptide being tossed around by skincare experts. To the latter group, here is some information that you may find fascinating. To the former, here is some more buzz about peptides.
What Are Peptides?
Peptides are pieces of proteins made of amino acids. When the amino acids combine, they create specific peptides. That’s why you may have heard the word peptide mentioned in athletic doping scandals, pepto bismal, and skincare; there are hundreds of types used for many different things. We’ll keep to skincare, to keep the lesson brief. When peptides combine in a certain way, they make proteins and proteins are the building blocks of skin. Without them, skin texture changes, wrinkles appear, and skin becomes saggy.
Peptides and Skincare
While peptides are a clear member of the “ingredients to look for in a skincare product” team, it is important to remember, that this is just what they are, a part of a team, albeit very important ones. There is no single solution to all the aging problems, and peptides are no different. However, they do play a valuable role, helping to make skin more resilient and providing support for the skin’s fundamental building blocks.
Collagen is a protein made up of peptides, and forms peptides when it is broken down. The result goes into your wrinkle cream. When the collagen supply in your skin lowers with age, the peptides signal your skin to make new collagen. The most popular peptide for this function is palmitoyl pentapeptide (matrixyl). Smart consumers will look for this on the ingredient labels of items they are considering for purchase.
The small size of peptides enables them to penetrate to the deeper layers of the skin. When combined with copper, the peptide will deliver copper to those layers. Research shows copper has healing properties and seems to act as an antioxidant and promote collagen production.
Read Before Buying
Even though peptides are capable of great results, many things have to happen to ensure that they happen. Because they are products of broken down proteins, peptides may continue to break down in a topical cream, until they are rendered useless. They also need to be in a cream which will be thin enough to penetrate the skin. A peptide in a thick cream may sit on the surface of the skin, only to wash off before going to work.
