New Peptides

I’ve been researching some of the new peptides in antiaging skincare products and am adding them to my Peptide Glossary. Here’s a sneak peek for my blog readers.



Dipeptide-2

Dipeptide-2 is used primarily in eye creams. It improves lymphatic circulation and helps the skin clear away toxins. It is especially effective for drainage of under-eye bags, spider veins and rosacea.



Products which contain Dipeptide-2 are:

Hylexin;

Murad Resurgence Renewing Eye Cream.



Heptapeptide-6

Heptapeptide-6 is a pro-sirtuin peptide which works topically by extending skin cells’ life span. See also Palmitoyl-Tetrapeptide-10. Heptapeptide-6 promotes the activity of the enzyme sirtuin. Sirtuins are believed to halt the normal cellular cycle that ends with old cells committing suicide. Instead sirtuins help rejuvenate aging cells by strengthening their DNA repair processes and stimulating production of protective antioxidants.



According to Wikipedia, “Sirtuins may be able to control age-related disorders in various organisms and in humans. These disorders include the aging process, obesity, metabolic syndrome, type II diabetes mellitus and Parkinson's disease.”



In an article in the journal Nature, Harvard Medical School lead researcher Dr. David Sinclair reported, “It's looking like these sirtuins serve as guardians of the cell. These enzymes allow cells to survive damage and delay cell death."



"What we think is that if a cell is at a point of deciding whether to live or die, these sirtuins push toward the survival mode and let the cell try a little harder and longer to fix itself," said Sinclair.



Products that contain Heptapeptide-6 are:

Avon Anew Ultimate Age Repair Cream; and

Avon Anew Ultimate Age Repair Elixir.



Palmitoyl Tetrapeptide-10

A pro-sirtuin peptide which works topically by extending skin cells’ life span. See Heptapeptide-6 for further explanation.



Products that contain Tetrapeptide-10 are:

Avon Anew Ultimate Age Repair Cream; and

Avon Anew Ultimate Age Repair Elixir.
