Trehalose and Bare Escentuals' New Moisturizer
Trehalose is made up of sugars that form a gel as cells start to dehydrate. This stops the cells from falling apart so that they perk back into shape as soon as they are rehydrated. Furthermore, trehalose is an antioxidant (as such it used as preservative by the food industry) and supposedly helpful in preventing degenerative diseases such as Alzheimer's.
Similarly, myrothamnus flabellifolia is an African tree that also 'resurrects' itself by using protective lipid films. It has been widely researched and is used in traditional African medicines. This is also one of the moisture retention ingredients in Purely Nourishing Facial Moisturizer.
It also seems that trehalose helps other ingredients penetrate cells. A good thing, since there are other worthwhile ingredients in Bare Escentual's moisturizer. These include vitamin C-rich pomegranate and antioxidant oat kernal and soybean. I was especially intrigued to see honeysuckle flower extract. This contains saponins that synthesise hyaluronans for water retention. Soy also contains saponins and I read somewhere that they can increase hyaluronan synthesis by over 200%.
The only ingredient of concern is dehydroacetic acid, a preservative that has been shown to be toxic if absorbed orally in animal studies and the European Union warns that it should not be used near the lips. But other than that, Bare Escentuals' new moisturizer seems well worth checking out.
