Reviews
I'm 38 and have tried every copper peptide serum on the market. INVIRA absorbs better than anything else. No sticky residue, no fragrance, no theatre. Skin looks visibly better after three weeks.

GHK-Cu Serum
The bottles feel premium and the formulations work. Only knock is shipping took a day longer than expected, but worth the wait.

GHK-Cu Serum
I'm 42 and have spent thousands on skincare. This serum is the first product where I actually saw a difference in two weeks. My skin looks plumper, smoother, and the fine lines around my eyes are noticeably softer.

Questions
GHK-Cu is a naturally-occurring copper peptide — a tripeptide bound to a copper ion. It's the most clinically-studied skin signal peptide in the world. Published research shows it supports skin firmness, hydration, and the appearance of fine lines. It's the active backbone of every INVIRA product.
Our formulations are fragrance-free, dye-free, and avoid common irritants like ethanol, sulfates, and synthetic preservatives. Most sensitive-skin users tolerate copper peptides well. If you're concerned, patch test on your forearm for 48 hours first.
Most users report skin feels softer and more hydrated within 7 days. Visible improvements in fine lines and overall radiance typically appear at the 4-6 week mark with daily use.
Cleanse with the Cleansing Mousse, sweep on the Toner, press in the Serum, then seal everything with the Wrinkle Cream. Use the Face Mask 1-3× a week and the Body Lotion daily.
No — the Serum is the hero and works on its own. The Toner and Wrinkle Cream complete the core ritual, while the Cleansing Mousse, Face Mask, and Body Lotion extend it. Start with the core three and build from there.
