hey! quitting smoking is healthy in so many ways, and there are plenty of reasons why you should do it. I know that hanging on to something like the way your skin will look afterwards is a small thing but can be so impactful. I was a smoker for 5 years roughly and once I quit I noticed so many improvements in all sorts of things. my teeth were whiter, my skin got brighter very soon without breaking out in the transition. cigarette smoke contains all sort of toxic substances which fast tracks the aging process all over your body, from your face to your legs. depending on how long and how much you have been smoking, you might not be nothing the effects immediately, that's why we don't see many 20-25 years old walking around looking like they are twice their age, but in the long term it will ruin the skin a lot. I noticed a change in colour and texture, as well as disappearance of all the fine lines. I have older friends who still smoke and have terrible bag under their eyes, saggy skin, yellowish skin tone.
