Neurogan Copper Tripeptide-1: this lightweight serum provides targeted support for fine lines and wrinkles for a younger appearance

Looks like a fake replica, the lid is black and the liquid is bluish.

After using it for 2 weeks , I’d to stop because my face dried up , became dull and deeper wrinkles .

It works great just give it a couple weeks and it works great.

This worked extremely well. Fixed my acne and made my wrinkles less noticeable. It's very easy to use and does everything it says it does.

Reviewing: Neurogan+Health CHK-CU Copper Peptide serum I read a couple books on the newer peptides, including skin topical peptides like Matrixyl and GHK-CU, so decided to give them a try. I'm giving 5-stars, but I haven't used GHK-CU or any of them by themselves. I followed advice and mixed them with a "carrier", in my case I had Cosmesis Advanced Triple Peptide serum, so I mixed all three together in roughly equal parts. I doubt the brand matters but be sure to know the ingredients sufficient enough to be effective (peptides are smaller part ingredients). In my case I bought at Amazon 'Skin Perfection' Matrixyl 3000 (matrikin), 'Neurogan+Health' GHK-CU (copper peptide), and 'Cosmesis' Advanced Triple Peptide Serum. From the first application overnight -- I saw a very clear improvement in my skin the next morning. You have to cycle peptides, so I only use it every other week. My skin has never, ever looked so good (I'm in my 50s with naturally good skin, but with aging, I needed a makeover. After a couple weeks, I started micro-needling it in while still half most. That's when my waitin' was over, rocking results. It's been about two months, skin looks fab. P.S. keep peptide products in refrigerator upon delivery, otherwise, they lose their effectiveness. I'm posting this same review for Matrixyl3000 product. disclosures: I have no financial interest in any of these skin products or any peptide products; this review is strictly my personal experience that I thought others would want to know about. Do your own homework, this review is not medical advice of any kind nor am I a medical doctor.
