this serum really does what it promises, it's wonderful!!

One of my holy grail products when it comes to preventing signs of aging and stress on my skin. I usually use it all year round or alternate with other active products. The consistency is very liquid, so I would recommend using very little at a time, or mixing it with a gel like hyaluronic acid serum for ease of application. I would recommend this to anyone, as it is non-irritating and very easy to incorporate to any skin care routine. A+++

I liked this product, but I won't repurchase it. The texture is too liquid for me, it gets absorbed right away before I can spread it on my face. I'd rather try The Ordinary's buffet serum with copper peptides, that's more complex and significantly cheaper.

I feel that I have tried a lot to like the products of NIOD, but I believe that they are not effective on my skin. They are just ok! This product was ok for some days, I felt certainly more moisturized, then that was it. The product turned darker and I did not feel moisturized any more. I understand that maybe you need to use this serum for a long time to see results, however it is an expensive product to invest without seeing actual improvement for a really long time. I would not buy this product again, I would rather try some other copper product!

I have tried the buffet and copper peptides from The Ordinary and thought that I will like this even better, as it is more expensive and from NIOD. But this is not the case. It is nice serum, it calm down my skin when it is irritated mainly now in the winter. But the same was with The Ordinary product, so I would recommend that one over this one.
