All peptide comparisonsQuick Summary
A copper-binding tripeptide used as a topical cosmetic ingredient, studied in animal wound models and in small short facial trials. Available from 60 vendors, priced from $14.99 to $1251.00.
Research: The 60-person study with a 22% firmness increase and a 16% fine-line reduction could not be traced to any paper, datasheet or database and has been removed. It circulates on vendor pages that cite nothing themselves. What is defensible: several small, short controlled facial studies exist, and the wound-healing evidence is chiefly ANIMAL, including a rat full-thickness wound study reporting 64.5% healing against 28.2% in controls at day 13.
Side effects: No adverse event table was verified for this page, and the injectable route has none at all
Research compoundWidely used as a topical cosmetic ingredient. The peptide's principal researcher founded two companies that commercialise it, which is worth knowing when reading its literature.
