The likes of Palmitoyl Tetrapeptide-7 and Dipeptide Diaminobutyl Benzylamide Diacetate get a lot of hype, but even skin care mavens often don’t know what they are, or how to pronounce them. But peptides aren’t just for the pros; they can boost your everyday routine in ways that make a real difference to your skin, and help you feel healthier and younger.
So what are peptides? Simply put, they’re short chains of amino acids, which are the building blocks of protein. Amino acids are responsible for everything from repairing body tissue to regulating hormones and optimizing organ function, so they’re really essential for a healthy life.
Peptides are shorter than full proteins and are more easily absorbed by the body, which is why they’re often found in foods, supplements, medications and skincare products. They’re also more effective than whole proteins because they are able to penetrate the cell and work directly on its functions.
Generally, there are three different types of peptides: carrier peptides, signal peptides and inhibitor peptides. Carrier peptides stimulate enzymes in metabolic processes and deliver essential trace elements to the cells. Signal peptides encourage the production of collagen, elastin and hyaluronic acid by fibroblasts. And inhibitor peptides suppress the release of neurotransmitters that cause muscle strain and, indirectly, wrinkles.
All in all, peptides have the power to positively influence cellular communication, restructure DNA and turn back the clock on common concerns like fine lines and wrinkles, melasma, uneven pigmentation and dryness. So it’s no wonder they have become a key ingredient in all our favourite skincare formulas.
