Summarizing my answer to Amy about pro-sirtuin anti-aging ingredients.
Sirtuins are enzymes which regulate fibroblast life spans. Promoting the work of sirtuins in the skin has been shown to extend cells’ life spans – slowing and even reversing the skin’s aging process.
Thus far, several pro-sirtuin peptides have passed clinical trials and are available in anti-aging creams. You can read about the pro-sirtuin effects of Heptatpeptide-6 and Palmitoyl Tetrapeptide-10 in my Cosmeceutical Peptide Glossary.
Estee Lauder claims pro-sirtuin activity for its trademarked Resveratrate but has not yet publicized any of its research. I withhold my opinion pending such information.
Pro-sirtuin peptides are found in Avon Ultimate Age Repair Cream, Avon Ultimate Age Repair Elixir and Dior Capture Totale Multi-Perfection Cream (buy at a discount from Strawberry.net and get free international shipping).
Resveratrol is found in Estee Lauder Re-Nutriv Ultimate Youth Crème but as Amy noted, the cream is difficult to find in many areas.
