Pairs well with

The copper tripeptide, at the concentration the research uses. Not a trace, not a blend that hides behind a proprietary name — one percent GHK-Cu, printed on the front of the bottle, in a formula built so you can actually stay on it.

Panthenol holds water in the upper layers so the peptide is not working on dry skin. Betaine buffers the sting that makes people quit copper on day four.

Application

  1. (01)

    Four drops, bare skin.

    Straight after cleansing, before anything heavier. Press in; do not rub.

  2. (02)

    Morning and night.

    Both. It is not a treatment you schedule your week around.

  3. (03)

    Keep acids on other nights.

    Direct acids inactivate copper peptides. Alternate them, do not stack them.
