Revive DNA Rejuvenation Cream ($99.97) by PureRadiance is now at the TIA store.  I have been using it recently as a neck cream and I am very pleased with the results. The skin on my neck had been getting rough and a little scaly and it is now beginning to look much smoother.

The refreshingly short ingredients list includes teprenone. This has been uses for a while as a non-toxic treatment for ulcers (usually called geranylgeranylacetone). It has recently been found to be a heat shock protein inducer. Heat shock proteins (HSPs) are well known as cytoprotective proteins and recently have been linked to the regulation of telomeres activity.

Revive also includes xylitylglucoside anhydroxylitol xylitol, a sugar found in wheat and olives that helps skin retain moisture and boosts the skin’s natural hyaluronic acid. It improves the barrier function of the skin, increasing ceramide synthesis. There is also a Middle Eastern plant called astragalus. Topically, it can also be used to treat wounds and burns. According to the University of Maryland, it is an antioxidant and anti-inflammatory.

Behind PureRadiance is Dr Al Sears, a health and aging guru. Initially, I was put off by his tacky websites selling supplements called Primal Force that look as if they should be selling Viagra. And when Dr Sears promises to "switch on your immortality" gene, there is more than a whiff quackery about him. One of the things he is known for is insisting that aerobic exercise and long-distance running are bad for you. So I decided to buy his exercise book PACE and see whether Sears was indeed nuts.

PACE is not a revolutionary theory. Dr Sears is basically advocating interval training. However, his arguments are well made and backed by plenty of references to independent studies. I felt inspired to modify my own exercise program (using a rowing machine) to follow his suggested sets of short bursts that push the heart rate followed by rapid recovery periods. I definitely felt that I had had a better workout that I've had for a while. One thing is for sure, Dr Sears could do with an image consultant.
