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.
