Carnosine is a relatively new discovery of mine and one that has me excited because it is reputed to extend the Hayflick Limit (the number of times a cell can divide and regenerate into a healthy new cell). I discovered it in a cream called Rejuvion made by a Swiss company, EOS. Curious to know how widespread the use of carnosine is, I did a spot of foraging and came up with the following products that contain carnosine:
Olay has reformulated Regenerist Replenishing Cream to include carnosine. Given that this potion costs less than $20 and has such an advanced active ingredient as carnosine plus matrixyl, it is hard to complain. However, the curmudgeon in me knows no such restraint. There is an awful lot of silicone in Regenerist, just about every paraben under the sun and a couple of perfumes that are known to cause contact allergies in relatively small doses. Not for the sensitive. The packaging for this range is beyond wasteful.
And now for something completely different. Youthful Essentials is a member of the Campaign for Safe Cosmetics and its Wrinkle Serum is blissfully simple. In addition to carnosine, it has vitamins A, C and E, aloe vera, green tea and DMAE. And that's about it. Could be a candidate for the next update of Truth In Aging's Five Best serums.
True Essential claims it was spa product of the year in 2007. Its Firming Tech Cream has carnosine, but it appears a long way down the ingredients list so there may not be much of it. Having said that, True's ingredients include lots of good things: matrixyl, green and white tea, vitamin E and squalane. Oddly, the dominant ingredient is extract of kigelia africana (also known as a sausage tree). The fruits are much favored by baboons and although I've never seen a wrinkled one I can't find any evidence that the sausage tree is an anti-ager. It is said to be a cure for eczema, however.
The makers of Isomers Carnosine Anti-oxidant Complex (a husband and wife team) claim that this patent-pending product will turn the anti-aging industry upside down and blow your socks off. Somehow, I don't think so. There is some shea butter, an emollient that is also good for dispersing vitamins, some pine, grape, tea and bark extracts. And, of course, carnosine. Plus a couple of parabens and silicone. Pretty good, but not revolutionary.
Elizabeth Arden First Defense Advanced Anti-oxidant Cream gives me an excuse to remind the world about wolfberries. They are a gazillion times more anti-oxidant than blueberries. I drink a couple of ounces of wolfberry juice every day and swear I have more energy. Other than the fact there are wolfberries and carnosine in this Elizabeth Arden cream, I can't say much more because I couldn't find a detailed ingredients list online.
The dominant ingredient in Dr Brandt Lineless Anti-Glycation Serum is Methylsilanol Hydroxyproline Aspartate, a protein found in collagen. As well as carnosine, there is soy bean and grape seed extract. Unfortunately, there is tricaprilyn, found to be toxic during animal tests, and plenty of parabens.
