Skin is made up mostly of collagen – it is the foundation that gives your skin its support and thickness. Young people have lots of collagen and taut, smooth skin. In contrast, older people have much less collagen and thin, wrinkled skin. Collagen is protein and is made up long chains of amino acids strung together, like chains of linked building blocks. When it is broken down, short segments of 3-5 amino acids form, called peptides. Peptides are not just junk collagen; these “mini proteins” are active molecules and no matter your skin type, peptides might be the anti-aging, hydrating, plumping, skin-renewing, fortifying skincare addition you’ve been seeking.
What are peptides?
Proteins, such as collagen, are made up of amino acids and arranged in a long chain-like format. This chain of amino acids is made up of peptides. The chain is then broken down into smaller chains, which are able to penetrate the top layer of skin, sending signals to skin cells and letting them know how to function.
As these smaller peptide chains effectively penetrate into skin’s deeper layers, they get to work on a cellular level and the signals they send can change the way skin cells function.
While peptides can be natural or synthetic, the ones used in skincare tend to be synthetic as they offer more control over how stable and effective the peptide is, as well as how it behaves.
How do peptides benefit from the skin?
Peptides signal our cells to create more proteins. They’re very specific and can only signal a cell that has the associated receptor. All cells in our bodies have receptors, but they’re only receptive to the right peptide. This is why it’s key to know which peptides to integrate into our skincare routine. Choosing the peptide that targets specific cells is how we can garner the exact benefits we want.
Collagen production; the pinnacle of anti-aging skincare
Our skin is mostly composed of a particular protein—the protein we seek in our skincare products; the protein that is produced at a significantly slower rate as we age; the protein that gives our skin its brilliant youthfulness—collagen.
Peptides are the source that feeds and stimulates new collagen production. They signal our bodies to generate more collagen proteins as collagen breaks down, so you can imagine how instrumental peptides are in maintaining young, healthy, and beautiful skin. Specific peptides will signal elastin and collagen proteins to look and act ‘younger’. Not only do collagen proteins give our skin its youthful and fresh appearance, but they enable our skin cells to behave in a tight, firm, and resilient manner.
Wrinkles and fine lines eradication
Skincare gurus often rave over anti-aging products, like tripeptide 5 cream, that stimulate collagen synthesis by use of specific peptides known to firm the skin and correct wrinkle – or, if you really want to give your skin some love, be a glow-getter. Studies showed intense reduction of wrinkles in subjects who used collagen-like peptides.
Skin hydration
When we absorb or ingest peptides, they know where to travel in our bodies to provide us with the utmost benefit. Peptides are essentially magnetized to our needs. If our skin is lacking in hydration or moisture, our bodies will reorganize the amino acids in the peptides we consume or apply and reassemble them into hydrating structures. Peptides that are small enough in composition for our skin to absorb will signal our skin to repair itself and alleviate dehydration by producing more water-retaining cells and proteins.
Not only do these intelligent protein-builders prompt our skin to produce new collagen, but they boost our hyaluronic acid production too. Hyaluronic acid is key to retaining moisture in our skin. A single gram of hyaluronic acid can hold up to six liters of water, and peptides effectively increase our natural production of this miraculously hydrating substance.
