Reality check — smoking totally ruins your skin and teeth. This BuzzFeed video is not a Halloween tutorial (unless your costume is you as your great-grandmother). With the help of makeup, each participant go to see what their skin would look like after 30 more years of smoking. While some of the wrinkles can be chalked up to natural aging, there are some obvious cigarette side effects. Yellow-stained teeth, lip lines, and sagging skin can all be caused by a daily puff habit. The nicotine in your favorite cancer stick limits the blood flow to your skin, causing you to lose elasticity and age-defying antioxidants over time. This is one case where vanity could save your life.
