Peptides: What are they really, and how do they premote healthy skin

2049In skincare, the term, “peptides” is loosely thrown around; you can probably find a product that includes peptides in almost every store you walk into.Three weeks ago,  I started having some eczema flare-ups on my hands.  This is nothing new for me.  I have flare-ups every once in a while, and as usual, it was extremely itchy and uncomfortable.  I was on my was to work when my skin started itching. I looked in my purse;  the day before I stayed overnight with a friend, and the only moisturizer I had with me was my Renaissance night cream; so sure enough, I put that on my eczema just as a moisturizer for the time.

As the days passed,  instead of just getting some hand lotion,  I just kept using my Renaissance night cream;  for no particular reason except that it was already in my purse.  After a few days,  I found that not only did the itching subside, but the rashes were healing a lot faster than normal and the wrinkly appearance and feel of the rashes, smoothed  in a much shorter amount of time than usual.

I mention this because of the relationship that peptides have with healthy skin, and the role they play in reversing the hands of time.

What is a peptide?

A peptide is literally a chain of amino acids that are chemically linked together; a chain of 50 or more peptides would then be considered a protein, of which there are many types.

What does this mean for our skin?

Collagen is the protein that gives the skin its elasticity.  Collagen, like all forms of protein, is made of peptides, which are made of amino acids.  Once collagen breaks down into peptide links, the body is supposed to make more peptides to complete the link and form the collagen protein again.  As we encounter skin damage, whether it be from aging, ultra-violet sun damage, or even skin disorders;  the body may loose its ability to make the peptides needed quick enough in order to combat damage.

Topically applied peptides are small enough to break through the skin’s protective barrier.  In a sense, when you apply peptides directly to your skin, you “trick” the body into making additional peptides at a quicker rate in order to fill what is needed to make a complete protein chain.

The Renaissance night cream is full of antioxidants and moisturizers that promote healthy skin, and with the added peptides,  this cream helps reduce wrinkles, and gives our skin the “ammunition” it needs in order to protect and heal itself.
