I smoked for nearly three decades. For the first two, I had serious thoughts of quitting and even many attempts. It wasn't until I reached the last decade that I began to think about the skin benefits of quitting smoking for women. I had noticed changes in my skin, but I was never sure if they were actually changes due to having been a smoker, or just aging in general. As a smoker, I was prone to being in denial and was therefore prone to believing the latter.
Although the reason for finally quitting was mainly about health concerns, I have to say I did notice a difference in my skin afterward.
