4. Wrinkles
When you’re 80 you expect wrinkles, not so much when you’re 35. Smoking is known to promote wrinkles and can make you look a bit older than you really are. Smokers can expect to look about a year-and-a-half older thanks to the reduction in blood circulation that smoking causes. Tissues that are deprived of blood will end up damaged and that damage will be noticeable.
