Fast working

I can already see a difference after JUST 2 DAYS. I hope you guys keep it in stock. I really like this product. It is worth the price. I started today using it on my chest.

Doesn’t work, pilled

I used this serum until finished. I didn’t feel like it did anything. It also pilled on my face.

KNR Serum

My esthetician added this to my Neocutis regime several years ago and I loved it. I decided to try something new a while back and could definitely tell a difference. Snd jot in a good way. So, I am back to the KNR and I’m staying!

Good serum

I do find the KNR serum has lightened areas on my face that other products have not which is a big plus. The one thing I don’t like about this product is it feels sticky for a very long time. I can’t put my moisturizer on for a while. It definitely has its rewards though. I’m on my second bottle and will continue to use this product.
