Beauty Only Skin Deep?
Scientists at Newcastle University,
UK may have learned the secret to anti- ageing. Many before had made the
assumption that mitochondria played a major role in the aging process, but this
recent study gives us insight on which specific bio markers could help us turn
back the clock. Mitochondrial complex II is believed to be responsible for the
way our skin ages over time.
The activity of a metabolic enzyme in our skin cells
decrease as we increase with age. This decrease in enzyme activity is described
as a decline in “bio energy”. More specifically, activity significantly
declined in the cells of the lower dermis, also referred to as the reticular
layer, rather than the upper dermis. The reticular layer is also comprised of
connective tissue but is more tightly packed.
II activity was measured from 27 donors which ranged from ages six to 72.
Scientists found that cell’s proliferation rate decreased with age, and that there
was a significant decrease in the amount of enzyme protein in those cells that had
stopped dividing. This is a major
breakthrough that may revolutionize the way we develop cosmetics and anti-aging
serums, but this research is much larger than just aesthetics. Not only does
this give us insight on how we can get rid of wrinkles and sagging skin, but
this may also lead us to possibly prevent age related disease such as cancer
with regards to other major organs like the liver or lungs.
