Ingredients & Transparency
At ION BLUE, transparency isn't a marketing word — it's the whole product. Here is exactly what's in our GHK-Cu serum, how much of each, and why.
The full formula
| Ingredient (INCI) | Amount | What it does |
|---|---|---|
| Water (Aqua) | Balance (about 95%) | The base the formula is built on. |
| Propanediol | 3.00% | A plant-derived carrier and humectant that helps keep the formula even and skin hydrated. |
| Sodium Hyaluronate (500 kDa) | 0.50% | A hydrating ingredient studied for helping skin hold moisture. We use one defined molecular weight, 500 kDa, rather than a blend of fragments. |
| Copper Tripeptide-1 (GHK-Cu) | 0.10% | The active. A signal peptide studied for its role in skin. What is GHK-Cu? · Why 0.10%? |
| Phenoxyethanol, Ethylhexylglycerin | Percentage coming with our certificate of analysis | A widely used, gentle preservative system that keeps a water-based formula stable and safe. |
One peptide: pure GHK-Cu at a real, disclosed 0.10% (1,000 ppm). "Pure" means the 0.10% is GHK-Cu itself, not the weight of a supplier solution or a multi-peptide complex. No proprietary blends, no fillers, no fragrance, no diluted formulations. What the label says is what's in the bottle.
A note on the one number still missing: we don't yet have the exact preservative percentage in writing from our manufacturer, and we won't print a number we can't back up. We'll add it here as soon as the batch certificate of analysis confirms it.
