Koppā is a science-led skincare brand built around GHK-Cu — glycyl-L-histidyl-L-lysine copper, a naturally occurring copper-binding peptide present in human skin, and one of the most extensively studied ingredients in modern peptide skincare.
Rather than treating copper peptides as a supporting act, Koppā makes GHK-Cu the connective ingredient across its entire range. The Koppā Protocol is a three-step system: a 2% GHK-Cu serum as the concentrated first step, a capsule-delivery cream for hydration and skin barrier support, and a face-and-body balm stick for targeted application anywhere skin needs it.
The brand’s focus is skin health over time — hydration, barrier support, renewal and long-term skin quality — presented as a routine simple enough to keep rather than a regimen to manage. Formulas are fragrance-free and cruelty free, with the full INCI disclosed on every product page. Koppā is made for anyone interested in ingredient-led skincare and is not positioned as gendered.
