Palmitoyl Tetrapeptide-7
Summary
Cartalax is a tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson for cartilage and connective tissue. It is tissue-specific for chondrocytes and cartilaginous structures, supporting cartilage matrix synthesis, slowing degenerative changes, and promoting joint longevity. It is used in the context of osteoarthritis, joint aging, and athletic cartilage preservation.
Palmitoyl Tetrapeptide-7 (Rigin) is a cosmetic peptide consisting of palmitic acid linked to the tetrapeptide sequence GQPR (Gly-Gln-Pro-Arg). It was designed to mimic the biological activity of the IgG immunoglobulin C-terminus, which downregulates the production of interleukin-6 (IL-6), a key driver of skin aging and inflammation.
