Copper Tripeptide-1. 0.11% concentration. Clinically studied since 1973.

Most masks hydrate. BLU° repairs.

GHK-Cu (Copper Tripeptide-1) is a naturally occurring peptide that signals your skin to rebuild — collagen synthesis, DNA repair, barrier restoration, anti-inflammatory response. All in one 20-minute mask.

Key Actives

  • Copper Tripeptide-1 — 0.1%
    Stimulates collagen synthesis. Repairs skin barrier. Studied by NASA for wound healing in space.
  • Ceramide NP
    Restores the lipid barrier. Locks in actives. Reduces transepidermal water loss.
  • Panthenol (Vitamin B5)
    Accelerates wound healing. Deep moisture retention. Soothes irritation.
  • Centella Asiatica
    Anti-inflammatory. Supports collagen synthesis. Calms sensitized skin.
  • Gentiana Root Extract
    Antioxidant protection. Rare differentiator. Fights free radical damage.

Sheet Material

Lyocell non-woven — biodegradable, premium adhesion, delivers more serum per wear than standard cotton sheets.

The Active

GHK-Cu isn't new.
It's just been ignored.

Isolated in 1973 by Dr. Loren Pickart, GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring tripeptide that signals the skin to repair itself. Over fifty years of independent research documents its ability to stimulate collagen and elastin synthesis, reduce inflammation, accelerate wound closure, and upregulate antioxidant enzymes.

Most copper peptide products contain a trace amount — not enough to do anything meaningful. BLU° delivers GHK-Cu at 0.1%, the concentration used in peer-reviewed research. Not a proprietary blend with an undisclosed dose. The real number, stated plainly.
