Vesilute- Summary
- 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.
- Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.
