The real ingredients behind CopperTheory GHK-Cu skin, hair and scalp routines.

CopperTheory is built around GHK-Cu copper peptide, listed in our formulas as Copper Tripeptide-1. But every product also needs supporting ingredients that help with hydration, skin comfort, barrier feel, scalp care, cleansing, conditioning and texture.

This page breaks down the key ingredients across CopperTheory face serum, face cream, face mask, hair serum, shampoo and conditioner so customers can understand what each ingredient is doing inside the routine.

Our Ingredient Philosophy

CopperTheory is designed around one clear hero ingredient: GHK-Cu copper peptide. On cosmetic ingredient lists, this appears as Copper Tripeptide-1.

The goal is not to overwhelm customers with dozens of unrelated actives. The goal is to create simple skin, hair and scalp routines where every ingredient has a clear role.

A serum needs hydration, texture and peptide support. A cream needs moisturising and barrier-supporting ingredients. A hair serum needs scalp-focused ingredients. Shampoo and conditioner need cleansing, conditioning and hair-feel support.

What CopperTheory focuses on

✓GHK-Cu / Copper Tripeptide-1 as the hero ingredient
✓Hydration support from glycerin and hyaluronic acid
✓Skin comfort from panthenol and allantoin
✓Hair and scalp routine support from peptides, niacinamide and arginine
