Description
What it is
GHK-Cu is a naturally occurring copper tripeptide, and the blue color is the copper itself. It supports skin renewal, helps maintain firmness, and calms the look of redness for an even tone.
Peptides degrade sitting in solution, so SPEC ships GHK-Cu freeze dried at a full 50 mg. You mix your serum fresh at home, and the peptide is at full potency from the first pump.
In the box
One vial of freeze dried GHK-Cu, 50 mg, pale blue under a silver crimp with a tear-off cap. One vial of reconstitution solution. One polished silver airless Serum Base pump, 4 ml / 0.14 fl oz.
How to prepare
- Pop the cork off the reconstitution vial.
- Remove the cap completely from the GHK vial. It tears off.
- Remove the stopper and pour the reconstitution solution into the GHK vial.
- Pour the mixed GHK-Cu solution into the Serum Base pump. Your serum is ready.
How to use
Once daily, press 1 to 2 pumps into cleansed skin. Alternate with strong acids or retinoids rather than layering them in the same routine.
Topical use only.
