Repair or Copper

Two formulas. Two skin priorities.

Repair and Copper share the same hydrating base. The difference is which peptide approach you want to emphasize.

Copper

Concentrated copper peptide care

2% GHK-Cu for customers focused on visible firmness, elasticity, and making copper peptides the center of their routine.

OR
Repair

Balanced daily peptide support

1% GHK-Cu plus 1% PDRN for hydration, visible firmness, and stronger-looking skin in one daily formula.

Neither is better than the other. Choose Copper for a higher GHK-Cu concentration or Repair for a broader two-peptide formula.

Expression Lines

A more targeted approach.

Expression is designed for areas where repeated facial movement leaves visible lines, including the forehead, between the brows, and around the eyes.

What's inside

The actives, explained.

Every ingredient that earns a percentage on the label, and what it's included to do.

Good to know

Questions worth answering.

They’re two approaches, not two tiers. Copper is a 2% GHK-Cu formula focused on copper peptide. Repair is a balanced two-active formula that combines 1% GHK-Cu with 1% PDRN. Neither is an upgrade over the other — the choice depends on which formulation approach better matches your priorities.

Yes. Expression targets a different concern and can be layered with either Repair or Copper.

Copper peptide serums can be used in routines that also include vitamin C or retinoids. Sensitive skin may tolerate them better when introduced separately or used at different times of day. When first adding the serum, avoid layering several strong actives at once.

Keep them somewhere cool and out of direct light. The airless pump does most of the work by limiting exposure to light and oxygen, helping protect the formula throughout use.
