Been using this for a few months since receiving it as PR. Wasn't expecting much but I'm really loving this serum so far. Really lightweight, watery texture, absorbs really well, and great for layering without that heavy oily finish. A great copper peptides serum if you need anti-ageing properties.

I’ve been using the NIOD Copper Amino Isolate Serum 1% consistently and I really like how lightweight it feels. It absorbs quickly, isn’t greasy or sticky, and layers well under moisturizer. My skin looks a bit smoother and more “rested,” and I haven’t noticed any breakouts from it. It’s a great option if you want an anti-aging step that feels gentle and comfortable to wear.

Product was received as part of an educational promotion. I’ve been using NIOD Copper Amino Isolate Serum 1.00% consistently and love how lightweight and fast-absorbing it is. It layers well in my routine without feeling greasy, and I didn’t experience breakouts. Over time my skin looked more calm and even, with a smoother overall appearance and a healthier “bounce.” I also appreciate that it didn’t sting or cause noticeable redness for me, and I didn’t notice pilling when I applied it on clean, dry skin and followed with a simple moisturizer. If you want a gentle, high-performance serum to support a more resilient-looking complexion, this one is worth trying.
