What are Copper Peptides?
“Copper peptides are amino acid chains (peptides) that are bonded to copper 2+ ions (Cu2 +),” Chief Scientific Officer at Deciem, Prudvi Kaka tells us. “They are found naturally occurring in the skin and may support a wide range of skin functions including barrier function, collagen, and elastin production,” he adds.
The Benefits of Copper Peptides for Skin
“Copper peptides trigger your skin to visibly repair and rejuvenate and are used in skincare to stimulate your skin's natural production of collagen and elastin,” explains McKenzie Bolt, Director of Global Education at skincare brand, Biossance. It’s the reason copper peptides are so effective on fine lines, wrinkles, and sagging. “They’re great for those looking to reverse the signs of ageing,” Michael confirms.
Side Effects of Copper Peptides
“There is nothing to suggest copper peptides can cause any noticeable side effects. However, I’d advise against applying to broken or peeling skin and, as with any new skincare product, to take a patch-test before regular use. I’d also advise against combining copper peptides with direct acids, strong antioxidants and retinoids,” says Michael. Why? Take vitamin C for example: “as an antioxidant, vitamin C can be quite potent and although it can help with everything from wrinkles to hyperpigmentation - when mixed with copper peptides they cancel each other out. So, if you've been mixing these two ingredients without seeing any results - this is why!” Michael tells us. [copy]As for retinol, “this is a very temperamental ingredient and therefore doesn't work well when mixed with potent actives,” Michael warns. “When mixed with copper peptides, retinol can cause your skin to become extremely dry,” he tells us.
How to use Copper Peptides in your Skincare Routine
“Copper Peptides should be introduced when you start to notice the appearance of wrinkles and fine lines,” Michael advises. “Typically, I’d suggest introducing it into your routine from your late 20’s to early 30’s,” he says. “Think of them like a healthy gym session for your skin, keeping your elastin and collagen fibres of your skin strong and youthful,” Mckenzie adds.
So, where does this ingredient fit into our skincare routine? “Depending on how the copper peptides have been incorporated into a product, they can be applied before or after the application of thicker creams or serums,” Prudvi expands. “For the copper peptide products offered by DECIEM (such as The Ordinary Buffet Copper Peptides), they should be applied as the first step after cleansing and before other serums or creams in both AM and PM.”
As a reminder, it’s not recommended to use copper peptides at the same time as acids, retinoids, pure or ethylated vitamin C and strong antioxidants. “Should any of these ingredients be present in an existing routine, they should be applied separately, i.e. one in the morning and the other in the evening or alternate mornings/evenings,” Prudvi prescribes.

Final Verdict on Copper Peptides for Skin
If ageing skin is your concern, copper peptides could well be the cure. Introduced at the right stage and age, this must-try metallic has the ability to support collagen production, skin firmness, and elasticity as well as boost your skin’s defences against external stressors. And that’s pretty brilliant. Just be wary of how copper peptides slot into your routine. If you’re using direct acids, retinoids, vitamin C, or other strong antioxidants, the efficacy of your skincare ingredients could be compromised, and even cancelled out. In short, copper peptides need space in order to shine, and that’s when you’ll really notice the difference.
