NIOD Copper Amino Isolate Serum - CAIS 3 1:1 | 15ml

I use this daily, as part of my skincare routine, it's a tiny bottle but you need a tiny bit so I think it will last a few months, so it isn't actually as expensive as I feared. When applied it immediately gives a noticeable difference to my skin texture and my skin looks glowy and pores smaller. It isn't harsh or drying, hydration is something I focus on with my skin type (I have combi skin with enlarged pores and it can be both oily and dry!). The one downside to it is it does have a funky smell (though it disappears once applied- or maybe I'm just nosey blind!) it is quite strong sort of salty/ammonia type of smell which if you have a sensitive nose you might find particularly unappealing. However for me it is worth it for the results!

I have been using this now for 3 weeks and can see a huge difference in my skin. I love this brand and product.
