deciem niod cais cail review and comparison

It’s DECIEM sale time again so since I have already reviewed most of the NIOD line, I thought I would concentrate on the copper amino isolate products today! If you are a long-time reader of my blog you will know that the Copper Amino Isolate Serum is my absolute all-time favourite skincare product and I’ve now had a chance to use up the Copper Amino Isolate Lipid so here are my thoughts!

Copper Amino Isolate Serum 3 1:1 (CAIS3) RRP £65* is now in its third generation and it’s been a staple in my skincare rotation in previous forms since circa 2016. A copper peptide serum, unlike its previous incarnations, you don’t have to play scientist with this one as it comes premixed and it’s a blue watery liquid with a slight vinegar scent (don’t worry it dissipates very quickly!). It’s a pro-repair and pro-collagen serum that maintains healthy looking skin by targeting signs of skin ageing including textural damage, uneven skin tone, enlarged pores and a lack of radiance.

This is easily my favourite serum in my stash and while this one was received in PR, I have bought countles bottles of this myself and will continue to do so! My skin really does look and feel much healthier when I use this consistently. It’s more even, clear and firm and it really does what it says on the tin – it’s a must have! This sinks in quickly and can be used in the morning and evening, but it is recommended to not use with acids, Vitamin C, EUK, or strong antioxidants. I tend to keep my routine simple when using this serum as it does all the heavy lifting for me! After the first few bottles of this I went through, I noticed its effects more when I stopped using it and I always have it in my stash now!

Moving on to the Copper Amino Isolate Lipid (CAIL) 1% RRP £72 and this one took me a while to get my hands on as it was out of stock for so long! Nevertheless, I’m glad I finally got the chance to try it! Like CAIS, it’s a copper peptide formula but this one is suspended in squalane so melts into skin and takes on more of a balmy, gel, oil-like feel and it’s designed for evening use. Again, its pro-collagen, pro-lipid and pro-fat and aims for healthy looking skin. It also has the added benefits of building and enhancing skin elasticity. The same products as mentioned above should be avoided alongside this as well as resveratrol and ferulic acid and I tend to use this as my last step in a simple evening routine. My skin feels well supported and hydrated overnight and like with CAIS, overall, it looks better and healthier with consistent use.

If you’ve been on the fence about trying either of these due to their price, now is the time while NIOD have their yearly 23% off sale! My personal favourite is the serum, it fits better into my routine as I can use it both AM and PM and it also works out better value for me with the 30ml being £65. CAIL does go a long way and is lovely to use as a treatment (especially in winter!) but I just love the serum more!

CAIS comes in both 15ml and 30ml versions while the CAIL only comes in a 15ml tube. As well as the DECIEM website NIOD is available from Cult Beauty, Space NK and Beauty Bay.
