Stem cells are definitely going to be one of the highest tech anti-aging ingredients of the year (by which I mean actual stem cells, not creams that purport to encourage stem cell growth). Capturing human stem cells is controversial and ones from animals somehow unappealing (and carry risk of infection). Enter vegetal stem cells.
According to manufacturers in Europe that are working on this, vegetal stem cells divide in a similar way to human ones. One of these companies has used the stem cells of a rare Swiss apple that is noted for its longevity and excellent storage abilities. In in vitro
studies, it was able to extend the shelf-life of human skin by delaying aging.
Meanwhile an Icelandic company is using barley grain to the same end. It says that using plants is safe and inexpensive. In which case, expect to see vegetal stem cells cropping up in products within the year.
