BFFs are awesome.
Mine encourages me to go for a walk when I complain about the couple of extra pounds I’ve put on during my last trip to Italy, gives me a pep talk when I start doubting my writing and even helps me come up with new ideas for the blog.
My BFF just makes my life better. She makes me more confident. Keeps me focused on my goals so I achieve bigger and better things.
Skincare ingredients have their BFFs too. Peptides and copper, for example. Together, they’re called copper peptides, and rumour has it, they work even better than retinoids. Can you believe it?
Here’s all the gossip (and the truth in it):
What The Heck Are Copper Peptides?
Peptides are proteins made up of amino acids, the building blocks of life. Some of these peptides have an affinity for the metal copper. When they meet, they hug and bind to each other really tightly.
That’s when peptides and copper become one: a copper peptide.
It can happen naturally in the body. Copper peptides are present in trace amounts in saliva, blood plasma, and even urine (eww, I know).
Or it can happen in a lab. A scientist mixes amino acids with a solution that contains copper and a copper peptide comes out.
P.S. In case you were wondering, the copper peptides found in our skincare products come from a lab.
Are Copper Peptides A Powerful Weapon Against Premature Aging?
It seems so.
Science says copper peptides can increase the production of collagen, the substance that keeps skin firm. The more skin makes, the less likely it is to sag and wrinkle.
There are also a few studies that say copper peptides do this so well, they produce more collagen than vitamins A (retinoids) and C, two of the most powerful anti-aging superheroes ever.
Pretty impressive, right?
Should You Replace Your Vitamins A and C Serums With Copper Peptides?
There are two reasons why I won’t be making the switch anytime soon:
- The studies I’ve just mentioned were done in vitro (petri dish), not in vivo (on real skin). See the potential problem with this? Just because something works in a petri dish doesn’t mean it’ll work when applied on the skin.
- Copper peptides don’t improve the texture of the skin. Vitamins A and C can also reduce roughness and dark spots. Copper peptides can’t.
Having said that, if you can afford to add a serum with copper peptides to your skincare routine (they can cost a pretty penny) do it! Anything that promotes collagen (and isn’t dangerous, of course), is always worth a try.
What Else Do Copper Peptides Do?
Copper peptides are quite the workaholics. They:
- have anti-inflammatory properties that soothe irritations, one of the main causes of premature aging.
- help heal wounds
- help heal scars by getting rid of the extra large, damaged collagen in them
- promote the production of elastin, glycosaminoglycans, proteoglycans, and other building blocks of the skin’s protective barrier
- produce enzymes that are essential for skin’s health, including antioxidant superoxide dismutase and lysyl oxidaze (it weaves together elastin and collagen).
Sounds Great! Are There Any Side Effects?
It doesn’t seem so.
Unlike silver, copper is metabolized by the body so there’s no risk of toxicity.
Some people report that too much copper triggers the production of metalloproteinases, which basically eat collagen and elastin. The result? Skin sags. Wrinkles appear.
Keep in mind, though, that there are no studies confirming this happening. Only a tiny minority of people who overused copper peptides reported this side effect. Until a study is done, we don’t know if this is true or even what defines overuse. A 10% concentration? Daily use? Who knows?
As I said, very few people experience this, so I’d say copper peptides are pretty safe.
What Are The Best Products With Copper Peptides?

The Bottom Line
Copper peptides are pretty expensive and there isn’t much research on them yet. But, what we know is promising so I’m including them in my skincare routine and recommend you do the same. But, only when the products have plenty of other proven-to-work ingredients. Just in case. 😉
