Kinetin versus retinol
On the other hand, Kinerase is based on kinetin, a substance that has been touted as the magical alternative to retinol.
At first blush, kinetin (also called N6-furfuryladenine) sounds promising as an active ingredient. For a start it's natural. Well sort of. Its a chemical analog for a plant hormone that promotes cell division. It is this dividing of cells - rather than killing them off so that new ones grow - that makes kinetin different from retinol. Kinetin is also touted as a powerful anti-oxidant (especially when combined with a vitamin B called niacinimide).
There are, however, a couple of problems with these claims.
The first is the human cells don't divide ad infinitum, but for a total of 52 times before reaching something that is called the Hayflick Limit (at that point its goodbye cell, hello wrinkles).
The second problem is that the anti-aging and anti-oxidation claims are based on two unpublished studies that were commissioned by Senetex, the manufacturer of kinetin. There is no reliable scientific evidence that kinetin is an effective anti-aging product. Furthermore, if it does speed up the time it takes to reach the Hayflick Limit, then it could be making things worse.
