Apparently it ages all your skin, not just your face and hands.
Smoking, for that all-over wrinkle! Prune up without staying in the bath!
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels beneath the skin to constrict, reducing blood supply to the skin.
Pleasant! Starving your skin of nutrients, evidently.
And my favorite bit:
Smoking can also damage the connective tissue that supports both the skin and the internal organs.
I wonder, if it were damaged badly enough would it stop connecting? Would your internal organs just start wandering through your body? Or just all come to rest on your pelvis?
