f you’ve done any research into anti-aging skincare, chances are you’ve come across the word "peptide".
While collagen is a long-standing staple of anti-aging regimens that we’re all quite familiar with, peptides are the lesser known newcomer on the scene. While the word “peptide” may bring you back to your high school chemistry class, it’s likely you’re wondering, "What exactly is it?"
Peptides are amino acids that make up certain proteins needed by the skin. More specifically, collagen is made of three polypeptide chains, so adding peptides can stimulate your skin to make collagen. More collagen can lead to firmer, younger-looking skin.
Your body makes collagen naturally, but over time, collagen production decreases, which can cause skin to look more wrinkled and less even and bright.
The collagen molecule is actually too large to absorb through skin, which is why so many people choose to eat collagen rich-bone broth or take collagen supplements.
But peptides can absorb into the skin where they can be used by the body. Incorporating peptides into your skin care routine has many benefits for the skin.
The skin barrier can be damaged from over exfoliating, exposure to cigarette smoke and other pollution, or even poor sleep. Peptides help build up a stronger barrier.
Collagen can plump lips and skin and when skin is firmer and plumper, wrinkles and fine lines will be less visible.
In addition to collagen, peptides also make up elastin fibers, also a type of protein. These fibers make skin look firmer and tauter.
Peptides can help ease inflammation repair damaged skin, and even out skin tone.
Some Peptides are antimicrobial meaning they can kill bacteria that cause acne.
There are so many products on the market that contain peptides, it can be hard to know where to start. Here’s how to shop for peptides, plus seven skin care brands to consider:
-
Pick the right form. You’ll want to choose a product like a serum or a moisturizer that has prolonged contact with your skin. A cleanser, for example, won’t be as effective because it’s rinsed off.
-
Choose your other ingredients WISELY. Peptides work well in tandem with other ingredients, including Vitamin C, niacinamide (but don’t use niacinamide and vitamin C together!), antioxidants, and hyaluronic acids. Using a peptide with an Alpha Hydroxy Acid or other AHA's, will actually make the peptides work less efficiently.
-
Look at the label. You ideally want to see peptides listed close to the top of the ingredient list. They may also be listed as “palmitoyl.”
In addition to anti-aging, studies show that the right peptide skin creams play an important role in repairing wounds and improving skin conditions. including eczema and dermatitis.
