A-Z — Peptides

rh-Polypeptide-66, also known as SIRT-1 (Sirtuin-1) is a synthetic peptide designed to mimic the function of natural peptides in the skin. It is known for its ability to support skin rejuvenation, enhance skin elasticity, and reduce the appearance of fine lines and wrinkles. KEY BENEFITS: supports skin rejuvenation, enhances skin elasticity, reduces the appearance of fine lines and wrinkles, improves skin texture and firmness, promotes a more youthful appearance.

Also known as Sirtuin-2 (SIRT2), sh-Polypeptide-67 is a synthetic growth factor peptide that mimics the natural growth factors found in the skin. It is known for its ability to promote skin regeneration, repair damaged skin, and improve overall skin texture and firmness. Cholesterol synthesis is mainly controlled by the sterol regulatory element binding protein SREBP-2.  Studies have shown that SIRT2 can lead to cholesterol biosynthesis by promoting the nuclear translocation of SREBP-2.

sh-Polypeptide-2 is a synthetic recombinant analog of human Thioredoxin (TRX) that stimulates dermal cell growth and proliferation and protects them from oxidative stress. Thioredoxin is a natural cytoprotector peptide present in all human cells. TRX is localized in the cytoplasm of cells and under oxidative stress it quickly moves into the nucleus, protecting the cell from damage. Thanks to potent antioxidant action, it reduces free radicals, preventing skin cells' programmed death (apoptosis) while reinforcing the skin’s defenses. sh-Polypeptide-2 (former rh-Oligopeptide-4; rh-Polypeptide-2) reduces the number of free radicals, and forms disulfide bonds in proteins, promoting the formation of the correct tertiary structure of...
