CKYN Launches Three-Step Copper Peptide Skincare System

Sunday, June 21st, 2026 - CKYN LLC announced the launch of The Complete CKYN Protocol, a three-step copper peptide skincare system manufactured in the United States, according to a company news release issued Saturday.

The Kirkland, Washington-based company said the system is designed as a daily skincare regimen built around copper peptide technology. Copper peptides are short chains of amino acids bound to copper ions, used in topical skincare products for their purported role in supporting skin repair and collagen production.

Product Details

The three-step protocol includes a cleanser, a copper peptide serum, and a moisturizer, the company said. CKYN stated the products are formulated without parabens, sulfates, or synthetic fragrances.

Company representatives said the system targets consumers seeking "clinically-inspired" skincare options, though the announcement did not cite specific clinical trial data or FDA clearance for the products.

Regulatory Context

Copper peptide skincare products are regulated as cosmetics by the U.S. Food and Drug Administration, meaning they do not require pre-market approval. The FDA does not evaluate cosmetic products for safety or efficacy before they reach store shelves, though companies are responsible for ensuring their products are safe and properly labeled.

Market Position

The launch adds to a growing market for peptide-based skincare products, which have gained consumer interest alongside broader peptide applications in medicine and wellness. Unlike prescription peptide drugs such as GLP-1 receptor agonists, copper peptide cosmetics are available without a prescription and make no drug claims.
