Your skin will look dull
One of the most common ways smoking takes a toll on your appearance is by turning skin dull, gray, and generally lackluster. Smoking depletes nutrients including vitamin C, which work to repair and protect damaged skin, nicotine hinders blood flow, and cigarette smoke is filled which carbon monoxide, which displaces the oxygen in your skin. All of these effects together leave you with unnaturally discolored and dry skin.
