“Lysosomes are cellular
organelles that contain acid hydrolase enzymes that break down waste
materials and cellular debris. They can be described as the stomach
of the cell...Lysosomes are
the cell's waste disposal system...”
http://en.wikipedia.org/wiki/Lysosome
“Mitosis is the most dramatic event
in a cell's life. Cellular structures that have always been there
suddenly disintegrate, new structures are constructed, and it all
culminates in the cell splitting in half.”
http://publications.nigms.nih.gov/insidethecell/chapter4.html#6
Basically, when a cell dies,
lysosomes eat up the dead cell. Another cell divides, and takes the
place of the dead cell. Cells, however, only divide a finite number
of times before they 'retire'.
“It turns out
that each cell has 92 internal clocks—one at each end of its 46
chromosomes. Before a cell divides, it copies its chromosomes so that
each daughter cell will get a complete set. But because of how the
copying is done, the very ends of our long, slender chromosomes don't
get copied. It's as if a photocopier cut off the first and last lines
of each page.
As a result, our
chromosomes shorten with each cell division. Fortunately, the regions
at the ends of our chromosomes—called telomeres—spell out the
genetic equivalent of gibberish, so no harm comes from leaving parts
of them behind. But once a cell's telomeres shrink to a critical
minimum size, the cell takes notice and stops dividing.”

What about a chemical peel? “In this treatment, a chemical solution is applied to the skin, which makes it 'blister' and eventually peel off. The new skin is usually smoother and less wrinkled than the old skin.” http://www.webmd.com/beauty/peels/cosmetic-procedures-chemical-peel-treatments
Duh! It's new skin. Of course it looks smoother and less wrinkled. But, it's new skin. You've just forced more cell division, speeding up the aging process for a temporary fix. Same thing with those 'age-reversing' retinols.
“...retinoids are still the gold
standard in anti-aging for their ability to accelerate skin cell
turnover...” http://www.prevention.com/best-retinols/
So, in striving to look younger, you
are actually speeding up the aging process.
What about laying out in the sun to
get that bronzed glowing tanned skin?
“Chronic exposure to the sun also
causes premature aging, which over time can make the skin become
thick, wrinkled, and leathery. Since it occurs gradually,...premature
aging is often regarded as an unavoidable, normal part of growing
older. However, up to 90 percent of the visible skin changes
commonly attributed to aging
are caused by the sun.”

Smoking speeds up aging too.
“And smoking
doesn't cause wrinkles only on your face. Smoking also is associated
with increased wrinkling and skin damage on other parts of your body,
including your inner arms. While the skin wrinkles may
not be reversible,
you can prevent worsening of wrinkling by quitting smoking now.
How does smoking
lead to wrinkles? The nicotine in cigarettes causes narrowing of the
blood vessels in the outermost layers of your skin. This impairs
blood flow to your skin. With less blood flow, your skin doesn't get
as much oxygen and important nutrients, such as vitamin A. Many of
the more than 4,000 chemicals in tobacco smoke also damage collagen
and elastin, which are fibers that give your skin its strength and
elasticity. As a result, skin begins to sag and wrinkle
prematurely because of smoking.
In addition,
repeated exposure to the heat from burning cigarettes and the facial
expressions you make when smoking — such as pursing your lips when
inhaling and squinting your eyes to keep out smoke — may contribute
to wrinkles.” http://www.mayoclinic.com/health/smoking/AN00644
So grab those cigarettes and hit
the beach. It's summertime. Don't forget to wash your face before
you go to bed with that special 'anti-aging' crème. After all, you
only live once, and you want to get old as fast as you can.
