Questions, answered honestly
-
Use copper peptides and vitamin C / strong acids / retinol at different times (for example, peptides in the morning, retinol at night), not layered in the same step.
-
With GHK-Cu, more isn't automatically better — too much can work against you. 0.2% actual active sits at the top of the studied range. We'd rather show you the honest number than inflate it.
-
Think 8–12 weeks of consistent use for firmness and texture, not overnight. It's a marathon, not a sprint.
-
The blue is the copper itself, not an added dye. Copper compounds turn blue and blue-green — the same chemistry that patinas a copper roof. When you see the color, you're seeing the active present in the bottle.
-
Everything. Use it daily for up to three months — peptides work on the skin's own turnover schedule, and that's the honest window for judging one. If you don't love what you see, email us and you get a full refund.
