I think many people wish to have a perfect skin or anti aging.
Yes, maybe we don't have to be afraid of getting old or aged sickness anymore.
According to Howard Chang Group of Stanford University's report on 29th November 2007, their research about the aging control by blocked a gene called NF-KappaB. It makes skin from aging and making it looks and act like it's new skin. Meaning, recovers injured skin.
Natural is good, but it's really an important discovery for medical history. Hope it would actually work on human being in the coming future. It helps aged sickness and cancer's patients.
