Here are some facts about smoking and how it effects your skin:
Collagen-destroying enzymes ramp up when exposed to tobacco smoke, dramatically increasing how quickly the skin will show visible aging. Tobacco smoke contains over 4,000 chemicals. At least 50 are known to cause cancer. Heavy smokers are nearly five times more likely to be wrinkled than non-smokers.
Lipid Peroxide (released in cigarette smoke) is the main free radical that destroys skin's barrier, resulting in dry, parched skin.
The eye area is the most affected area, due to collagen damage. A women's skin will be more affected from smoking than a man's skin.
Vitamin C decreases in the skin and body with tobacco/cigarette smoke.
A smoker's skin will appear gray, because capillaries are dying and closing off, which reduces blood supply and oxygen to the skin.
What can you do to prevent this? Well, besides the obvious of quitting smoking, Use products that stimulate collagen such as Peptides. Peptides are powerful ingredients that when used regularly will help the formation of new collagen.
