Kinetin may slow skin aging

Rough, wrinkled, and brown. It's not the worst thing that can happen whilst aging, but not particularly what you want for your cheeks, your neck, or the backs of your hands. N6-furfuryladenine, aka kinetin, promotes cell growth in plants and perhaps in your skin.

Here's one enthusiastic endorsement for kinetin kream from drugstore.com:

I absolutely love this product! As a woman of 50, I've found that Kinerase has given my skin a clarification or glow that I have not seen in years. I use it twice daily with my other moisturizer. When one of my friends asked me if I had some type of treatment (i.e. Botox), I knew this was the right product. Results do take time.

Dr. Suresh I. S. Rattan, PhD, DSc, Associate Professor of Biogerontology at the University of Aarhus, Denmark, who happens to be the patent holder for N6-furfuryladenine for use on aging skin says:

...when you grow normal cells in the lab they have a limited number of times they multiply and divide—termed a cell's replicative life span. But when I added N6-furfuryladenine to these cultures the cells did not age as fast, the process slowed down dramatically.

In a year-long study of 96 subjects with sun-damaged old skin, the majority of the studied leathernecks noted a decrease in fine wrinkles and roughness. A lucky third of them noticed less 'mottled hyperpigmentation.'

A final note of caution from Dr. Rattan, who basically warns that if a little is good, a lot is not better:

In cell cultures when a concentration of say 250 micromolars of N6-furfuryladenine was used, we got good results, but when we used 500 micromolars of N6-furfuryladenine the cells started dying.

Am I going to buy this stuff? I think not; a one month supply costs $65!
