During the 18th-century, Uttwiler Spätlaube apples were popular despite their terrible taste, as they had an unusually long shelf-life in an age with no refrigerators.
It turns out that Uttwiler Spätlaube apples contain remarkably active stem cells.
Stem cells are cells capable of self-renewal and posses the ability to regenerate other cells (both in humans and plants).
At a concentration of only 0.1%, an extract of Uttwiler Spätlauber stem cells stimulate the proliferation of human stem cells by an astounding 80%.
At the same time, the Uttwiler Spätlauber stem cells also protect human stem cells against ultraviolet light-rays.
As a result these apple stem cells repair damaged skin tissue and reduce the depth of wrinkles within days.
