You may be hearing more and more about peptides, an important ingredient in anti-aging skin care products. In the past peptides have often been overlooked while exfoliation gets all the buzz. Although exfoliation is important, we are finding out more and more about the benefits of peptides, all of which encourage the positive changes we like to see in our skin as it ages.
Peptides are proteins composed of long or short chains of amino acids, which are the building blocks of protein. They are found naturally in all of your cells. Products containing peptides function as moisture-binding agents and, here's the really cool part, almost all of them have cell-communicating ability to help skin repair itself and build more collagen. And building more collagen is very exciting when it comes to skin care and looking younger.
But not all peptides are created equal. In order for them to work, they must be included in a formula that effectively penetrates deep into the skin's dermis, rather than settling useless on the surface. Some of our favorite skin care products contain these peptides in effective, penetrating medical-grade formulas.
Peptides can be combined with other active ingredients, like antioxidants, to form a powerful anti-aging cocktail for the skin. Since it is not always obvious which products contain these collagen-building little wonders, we have listed our favorites here.
