·	Smoking affects matrix metalloprotienases (MMPs) causing collagen to degrade and elastin to fragment

·	While aging from the sun happens in the higher levels of the skin (dermis), smoking predominantly affects the lower, deeper part

·	Smoking lowers the blood supply to the skin and reduces collagen production. Both of which slow healing in the skin

·	This slow healing has an influence after surgery including after cosmetic surgery or laser resurfacing. It prolongs the healing process and increases the risk of complications

·	Nicotine, carbon monoxide and hydrogencyanide have toxic effects on healing tissue

·	Some suggest that nicotine may suppress the immune system to increase susceptibility of viral infections of the skin such as warts.
