You probably knew this, because smoking isn’t exactly a good habit to begin with. Every time you light up a cigarette, you reduce the amount of oxygen your facial skin gets. Additionally, smoking also speeds up the breakdown of collagen and elastin, which means speeding up the aging process, along with the increased pore size. The carcinogens in the smoke also irritate the skin and dry it out, triggering it to produce more oil and possibly more breakouts.
