You've probably heard how smoking causes more wrinkles, yellow teeth, and makes you age faster in general. But just hearing vague stuff like that probably won't help you quit. So here are six more SPECIFIC ways smoking can ruin your looks.
#1.) Cuts and Scrapes Are More Likely to Scar. Nicotine causes something called vasoconstriction (--pronounced vay-zo-constriction). Which is a narrowing of the blood vessels that limits blood flow.--Meaning when you cut yourself, it generally takes longer to heal, and you're more likely to have a scar there because of it.
#2.) You're More Likely to Develop Psoriasis. If you don't know, psoriasis is a common autoimmune disorder that causes scaly patches of skin. And even though treatments can help, there's still no cure for it.--According to a study from 2007, if you smoke a pack a day for 10 years, you're 20% more likely to get it. And after 20 years, you're 60% more likely.
#3.) It Gives You Bags Under Your Eyes. According to a study at Johns Hopkins, smokers are four times more likely to wake up feeling tired after a full night's sleep.--One possible explanation is that your body is going through a little bit of nicotine withdrawal while you're sleeping, which can cause you to toss and turn.
#4.) Smoking Makes Your Hair Thinner. This isn't definite, but some experts think the toxic chemicals in cigarette smoke can damage the DNA in your hair follicles.--And according to a 2007 study that took into account things like aging and genetics, cigarettes might significantly increase your odds of going bald. (--That study was in Taiwan though, so who knows.)
#5.) You're More Likely to Lose Teeth. A 2005 study in the U.K. found that smokers are up to six times more likely to develop gum disease. And gum disease is what ultimately causes your teeth to fall out.
#6.) You're More Likely to Get Stretch Marks. Non-smokers get them too. But nicotine damages the fibers and connective tissue in your skin, which makes it weaker and less elastic.--So stretch marks are usually worse if you're a smoker, or recently were. (Health)
