CKYN LLC Launches The Complete CKYN Protocol June 20: Three-Step GHK-Cu Copper Tripeptide Skincare System for Prestige Consumer Market — Documented 22% Firmness, 16% Fine-Line Reduction at 12 Weeks
CKYN LLC, a Kirkland, Washington-based skincare company, launched The Complete CKYN Protocol on June 20, 2026 — a three-step daily skincare system built entirely around GHK-Cu (Copper Tripeptide-1). The protocol comprises the Morning GHK-Cu Perfecting Lotion, Daytime GHK-Cu Tallow Balm, and Night-Time GHK-Cu Firming Serum. The product positioning anchors on six bioactives instead of the typical 20+ ingredient prestige skincare formulation, with concentrations targeted to clinical-study levels: published GHK-Cu research has shown 22% visibly firmer skin and 16% reduction in fine-line appearance after 12 weeks of consistent twice-daily application. GHK-Cu was first isolated from human plasma in 1973 by Dr. Loren Pickart and has accumulated four decades of cosmetic-science evidence. CKYN sits alongside Italgel avvera (June 12 launch) and GELITA CURADERM (Vitafoods Europe 2026) in the active 2026 cosmetic-peptide launch cycle.
