Questions
Asked often.
Still unsure? Text us at (000) 000-0000 or write to hello@covellskin.com. A person answers, Monday to Friday, 9 to 5 Central.
What is GHK-Cu?
A copper-binding tripeptide, glycyl-L-histidyl-L-lysine, that your body makes and that declines with age. In skincare it is made synthetically to match the natural molecule.
Why is it blue?
Copper bound to the peptide forms a blue complex. No dye is added. A paler serum means less copper.
How much GHK-Cu is in it?
2.0% by weight, the concentration used in the facial research. Most competitors do not state theirs.
Will it stain skin, hair or pillowcases?
No. It dries clear in about thirty seconds. Very light hair can pick up a tint from heavy, repeated use of copper products on the hair itself; the face serum is not for hair.
Does it smell?
Faintly metallic in the bottle, nothing on the skin. There is no fragrance in it.
Can I use it with retinol?
Yes, on alternate nights, or retinol at night and Covell in the morning.
Can I use it with vitamin C or acids?
Not in the same application. Vitamin C and low-pH acids can pull the copper off the peptide. Use them at the other end of the day.
Is it safe around the eyes?
On the orbital bone, yes. For the lid and lash line use the Eye serum, which is 1% in a gentler base.
When will I see something?
Hydration the first day, a smoother surface in one to two weeks, changes in the look of lines and firmness over four to twelve weeks. The published facial study ran twelve weeks.
How long does a bottle last?
About 60 days at four drops a day. The subscription ships every 60 days and can be paused or cancelled any time.
Is it vegan and cruelty-free?
Yes. No animal-derived ingredients and no animal testing, by us or on our behalf.
Is it safe during pregnancy or nursing?
GHK-Cu has no known restriction as a cosmetic, but we are not your doctor. Ask yours and bring the ingredient list.
Where is it made?
Formulated and filled in the United States in a GMP cosmetic facility. The peptide and glass are sourced globally, which is why we say formulated and filled in the USA rather than made in USA.
How should I store it?
Capped, out of direct sun, at room temperature. Use within six months of opening.
What if it doesn't work for me?
Return it within 30 days, used, for a full refund. Email or text us and we'll send a label.
