Is smoking bad for the skin?

Tobacco damages
the skin according to three main mechanisms. First, cigarettes contain
nicotine, a toxic substance that destroys vitamin C. In fact, nicotine is so
toxic that even non-smokers lose vitamin C when exposed to cigarette smoke.
This is a problem, among other things, because our body uses vitamin C to
produce collagen fibers that give the skin its strength. Collagen is the main
structural protein of the skin, which gives it its elasticity. When collagen
begins to break down due to lack of vitamin C due to the effects of nicotine,
the skin starts to wrinkle and sag.

Cigarette smoke is
harmful to the skin, especially because of its action on the blood vessels. The
blood brings oxygen and nutrients to the skin cells, but smoking causes
vasoconstriction, a decrease in the size of the blood vessels. As the blood
vessels contract, less oxygen and nutrients reach the skin cells. A cigarette
can reduce the supply of oxygen to the skin for up to ninety minutes, leaving
the skin gray and dull.

Smoking increases
wrinkles by 80%. By constantly pulling on a cigarette and squinting to see
through the smoke, wrinkles form.

imagine an apple
cut in half that starts to brown quickly. This phenomenon is due to the oxygen
of the air and is called oxidation: the air gradually destroys the flesh of the
fruit. Put salt on the apple to prevent it from browning so quickly. Salt acts
as an antioxidant on the apple and protects the flesh of the fruit. Some
vitamins such as A, C and E have the same effect on the skin and so it is
important to consume a lot of fruits and vegetables. However, people who have
smoked for a long time are usually ten years older than non-smokers of the same
age.
