Science is
the ingredient.
BLU° was built on one question: why does the beauty industry ignore the most studied skin repair molecule in existence?
Fifty years of science. One ignored molecule.
In 1973, Dr. Loren Pickart isolated a copper-binding tripeptide from human plasma. He named it GHK-Cu. Over the following decades, 50+ peer-reviewed studies documented its ability to stimulate collagen synthesis, accelerate barrier repair, reduce inflammation, and signal the skin's own regeneration cascade.
The beauty industry barely noticed. Instead, it spent the next fifty years marketing retinols, vitamin C serums, and peptide blends with clinical doses too low to do anything meaningful.
We built BLU° because the science was there — sitting in academic journals, verified by independent researchers across three continents — and nobody was delivering it correctly.
Three rules. No exceptions.
BLU° is not a cocktail. It delivers one molecule — GHK-Cu — formulated with supporting ingredients that serve a function. No ingredient is there to make the label look impressive. Everything earns its place.
GHK-Cu at 0.1% — the concentration used in peer-reviewed studies on barrier repair and collagen synthesis. Not a trace. Not a proprietary blend that obscures the actual amount. The concentration the science uses.
Every batch of GHK-Cu in BLU° is tested to 99%+ purity via a 16-point Certificate of Analysis, manufactured under pharmaceutical-grade conditions, and fully traceable from synthesis to mask. We don't source an active and assume. We verify it.
Everything the skin needs. Nothing it doesn't.
The BLU° mask is a premium Lyocell sheet saturated with 25ml of serum per mask. Lyocell was chosen for one reason: it holds more fluid in contact with skin, for longer, than any other natural fibre — maximising the time GHK-Cu has to penetrate the barrier.
Worn for 15–20 minutes, the sheet forms an occlusive seal. Moisture is trapped. The barrier softens. The copper tripeptide travels past the stratum corneum into the living epidermis — where it does its work.
No fragrance. No parabens. No silicones. Biodegradable. Suitable for sensitive skin.
We didn't invent GHK-Cu.
We just finally gave it a proper delivery system.
