Deciem NIOD Copper Amino Isolate Serum

Have you noticed there’s been a bit of chatter about copper peptides in skincare lately? The biggest player on the scene right now is NIOD’s Copper Amino Isolate Serum (CAIS), and it has people swearing that this is a liquid version of the second coming.

Unfortunately when an ingredient becomes trendy we see the market flooded with products claiming to be using the best of it. Copper Peptides are that hot-new ingredient right now but what exactly are they? I’ve chatted with Deciem’s co-CEO, Nicola Kilner, to get the lowdown on copper peptides and how you can make sure you buy a product that works. 

Copper Peptides Q&A

What is it? Exactly how is copper part of this serum? Is it just copper wire melted into a serum with a bunch of other skin-beneficial ingredients?

The product contains copper peptides rather than actual copper. Copper is actually itself a very bad supplement to the skin as it oxidizes. However, copper peptides which actually contain no copper are extremely important as they have a high affinity to copper (hence the name) and they draw copper from your body in to allow repair and protection. Copper peptides in human plasma decline by 70% by age 60 and therefore despite the presence of copper within the body, the body cannot use it for repair.

What can this form of copper do for skin? What does it treat? Who does it work best for? Are there any situations or conditions that it’s unsuitable for?

Think of it in this way: copper is a very essential part of immunity and repair. Copper Amino Isolate Serum offers an extraordinary concentration of nature-identical copper peptides that decline in everyone dramatically over time. Copper peptides are needed for cellular repair and, ultimately, if your cells repair the very small things that are always going wrong (effects of oxidation, pollution, stress, metabolism, etc.) then nearly everything just works and looks better. It’s the one single product I cannot be without.

What kind of results do people see from this product, and how quickly? 

Think of the Copper Amino Isolate Serum as a long term investment for your skin. It really depends on each person and their skin concerns as to how quickly they’ll start to see results, but usually people find within a week their skin starts to feel smoother, they have improved skin texture and overall their skin looks more radiant. In terms of results, copper peptides targets all signs of skin ageing, improves skin texture, minimises the appearance of pores, helps repair existing damage such as slight acne scarring and promotes overall skin health for benefits your future self will thank you for!

Is using copper a new thing in skincare? Why haven’t we heard about it until recently?

Many products now use copper as a trend. They should all be eliminated from the world. They’re a scam in the politest of terms. Copper firstly oxidizes and becomes harmful, it’s a very inexpensive metal and almost no one is deficient in it. Copper peptides especially tripeptide-1 (either GHK or AHK) is what’s important.

NIOD Copper Amino Isolate Serum

The NIOD Copper Amino Isolate Serum has been hugely popular for Deciem. Exactly how popular has it been?

It is in our top 5 all time best selling products, and is our best selling product under NIOD.

How should I incorporate this serum into my current regime? Are there any ingredients or treatments I should mix this product with?

NIOD’s Copper Amino Isolate Serum is so versatile it can be used with your existing regime but also powerful enough that it can be used by itself. The texture is actually thinner than water so it sinks into the skin beautifully and works really well when layered with other products. One thing to remember with layering your products is start with the thinner, most lightweight products first and then finish with the thicker and heavier products like your moisturiser. With this theory in mind, Copper Amino Isolate Serum is always first when applying within a regime.

If there is one reason to buy NIOD’s Copper Amino Isolate Serum, what is it?

The Copper Amino Isolate Serum keeps your skin in a constant state of repair and will continue to protect and promote overall skin health for any age and any skin concerns – it really is the one product I can’t live without!
