Peptides are a popular ingredient in skin care because they can help boost collagen, elastin and hyaluronic acid production to give your skin a healthy glow.
They can also help stimulate cell regeneration and support a strong skin barrier, which means they’re great for treating acne and reducing inflammation. But there are a lot of different kinds of peptides, some better studied than others, so it’s important to choose the right one for your skin.
How they work
Your body makes peptides naturally, but you can also get them from foods and supplements like bone broth. They’re chains of amino acids that are the building blocks of proteins.
The body sends peptide signals to tell the cells where it needs them, so they produce more of them in areas that need them. That’s why your body sends peptides to areas that are injured to heal them and stimulate more collagen production.
How they affect your skin
As we age, our bodies stop making proteins at a rate that supports healthy, youthful skin. Over time, the skin loses collagen and elastin, which can cause fine lines and wrinkles to form.
If you use a peptide-infused moisturizer or serum regularly, your skin will notice its glow improve. Some peptides can even help brighten skin’s appearance by reducing the look of sun spots and age spots.
How to use them effectively
Peptides can be found in a variety of products, but it’s best to use them in a regimen where they’re used along with other ingredients that address multiple signs of aging. That’s where antioxidants, hydrators and skin-replenishing ingredients work best.
