How does nicotine negatively affect the skin?

Nicotine negatively affects the skin primarily by contracting blood vessels, which leads to a reduction in blood flow and oxygen supply to the skin. This constriction of blood vessels results in a lack of essential nutrients and oxygen that the skin cells require to maintain healthy function and repair. The reduced oxygen supply contributes to an array of skin issues, including a dull complexion, an increased appearance of fine lines and wrinkles, and a slower healing process for wounds.

The impact of nicotine on blood vessels is significant because healthy blood circulation is vital for skin vitality and resilience. When the skin does not receive adequate oxygen and nutrients, it becomes more susceptible to damage, aging, and disorders. This highlights the adverse effects that nicotine consumption can have on overall skin health, confirming why understanding this mechanism is crucial for those in the esthetics field.
