Main Description
FIRMA is built around GHK-Cu — a naturally occurring copper tripeptide first identified in human plasma in 1973 and studied for decades for its role in collagen and elastin signaling. As we age, GHK-Cu levels in the skin drop sharply, which may contribute to the visible laxity that shows up earliest on the neck, jawline, and chest.
FIRMA pairs prescription-strength GHK-Cu 0.5% with four supporting actives — Tretinoin, Hyaluronic Acid, Vitamin C, and Niacinamide — in a single cream compounded fresh in a U.S.-based licensed pharmacy.
