LE CELLULE STAMINALI IN COSMETICA

LE CELLULE STAMINALI IN COSMETICA

Ciao girls, 

mentre cercavo opinioni su un prodotto su beautypedia http://www.paulaschoice.com/beautypedia/, mi sono imbattuta in una OTTIMA e sintetica analisi di Paula Begoun circa le cellule staminali che vi incollo qui sotto in inglese (se trasferite il tutto in google translate potete leggerlo abbastanza bene).

"Stem cells are cells in animals and plants that are capable of becoming any other type of cell in that organism and of producing more of those cells. Despite the fact that stem cell research is in its infancy, many cosmetics companies claim they are successfully using plant-based or human-derived stem cells in their anti-aging products. The claims run the gamut, from reducing wrinkles to elastin repair and cell regeneration, so the temptation for consumers to try these is intense.

The truth is that stem cells in skin-care products do not work as claimed. In fact, they likely have no effect at all because stem cells must be alive to function as stem cells. Once these delicate cells are added to skin-care products, they are long dead and, therefore, useless.

Plant stem cells, such as those derived from apples, melons, flowers, and rice, cannot stimulate stem cells in human skin, but because they are from plants these ingredients likely have antioxidant properties. Actually, it's a good thing plant stem cells can't work as stem cells in skin-care products; after all, you don't want your skin to absorb cells that can grow into apples or watermelons!

There are also claims that because a plant's stem cells allow a plant to repair itself or to survive in harsh climates, these benefits can be passed on to human skin. How a plant functions in nature is unrelated to human skin, and these claims are completely without substantiation.

Another twist on the issue is that cosmetics company's claim they have taken components (such as peptides) out of the plant stem cells and made them stable so they then can work as stem cells. This approach is not valid because stem cells must be complete to function normally. Even if you could isolate substances or extracts from these cells and make them stable, there is no published research showing they can affect stem cells in human skin."
