What Are Peptides?

You’ve likely heard the buzz around peptides as an anti-aging must-have and hero ingredient to smooth, repair and hydrate skin, but have you ever wondered what a peptide is and what it does for the skin, exactly? More important, is having it as one of the key ingredients in your skin care products worth the hefty price tag? The short answer, according to two prominent dermatologists, is yes.
Elastin and collagen are fibers in our skin. These fibers are made up of proteins, the building blocks of our skin and add to tissue firmness and elasticity.
Simply put: peptides are amino-acids that make up proteins, which make up collagen and elastin fibres, which give the skin its suppleness and strength.
Without these proteins, we will see wrinkles, brittle nails and dry hair that’s prone to breakage.
“We need peptides at all times. If we are deficient in them, our body cannot function,” says Dr. Robinson. “Peptides have a myriad of uses in the body, from being the building blocks for enzymes, hormones and an energy source.”
