Sirtuins claim to boost collagen growth resulting in firmer skin with fewer lines and wrinkles. Some of the products that are touting this new ingredient are Orlane Anti-Fatigue Night Repairing Creme, Estee Lauder Time Zone Line and Wrinkle Reducing Creme, and Avon's Anew Ultimate Age Repair (in day and night creme and elixer premium).
Sirtuins are natural protein enzymes in our bodies that act to repair cell damage and make cells live longer. While millions are being spent in pharmaceutical companies around the world, not much more is known about these proteins. In a Washington Post article lead researcher David Sinclair of Harvard Medical School reported that sirtuins appear to "serve as guardians of the cell" allowing cells "to survive damage and delay cell death. What we think is that if a cell is at a point of deciding weather to live or die, these sirtuins push forward the survival mode and let the cell try a little harder to fix itself." Sirtuins have also been found to increase collagen production.
So what does this all mean? Sirtuins look promising, but pharmacists are withholding judgement until they see more studies. When this ingredient is seen in prescription treatments, we will know it's the real deal.
