Smoking Cigarettes is considered the number one preventable cause of death in the US. Smoking is associated with cardiac and lung diseases as well as cancers of the lungs, mouth, and pharynx. However, did you know that smoking also has external effects on the skin.
There is documented research that smoking can have a direct effect on your skin. Squamous cell skin cancer, wrinkles/premature aging, and poor wound healing are among the more serious issues that smoking can lead to. Yellow and brown skin on the hands and nail staining as well as forms of acne (hidradenitis suppurative) are some of the less severe problem you can encounter as a smoker.
The best thing you can do for yourself is to quit smoking, and if you are not a smoker, avoid second hand smoke as much as possible.
