Will smoking affect my recovery scar revision & mole removal?

Yes. Smoking causes poor wound healing after any invasive procedure such as surgery, laser resurfacing, liposuction, etc..., including scar revision and mole removal, resulting in worsened scarring. In addition to lung cancer, smoking is also known to cause premature wrinkling and aging of the skin.
Yes. Every time you smoke - you constrict the small blood vessels to the skin. Wound complications and poor cosmetic results are much more common in smokers. For example, some plastic surgeons are very leery of immediate breast reconstruction or face lifts in smokers because of the potential for serious cosmetic side effects.
