According to experts, alcohol consumption causes blood vessels to dilate, increasing blood flow to the skin and causing facial redness, particularly around the nose. This effect is usually temporary, disappearing within a few hours.
However, regular alcohol consumption leads to a loss of elasticity in blood vessels over time, causing permanent dilation of the capillaries, which are particularly sensitive in the nasal area due to the thinness of the skin and its richness in blood vessels. Excessive drinking damages these capillaries, resulting in chronic redness and the appearance of what are known as "spider veins."
Alcohol addiction can also exacerbate a condition known as "rosacea," a chronic skin disorder that causes redness of the skin, especially on the nose and cheeks, and in severe cases may develop into an enlarged nose.
In addition, alcohol addiction negatively affects liver function, which is responsible for detoxifying the body. When liver function is impaired, harmful substances accumulate in the body, potentially leading to changes in blood vessels and contributing to redness and swelling of the face and nose. Alcohol also increases stress on the heart and blood vessels, which can raise blood pressure and cause vascular changes, with the nose being among the first to be affected.
The nose is more prone to redness than other parts of the face for several reasons, including:
Anatomy: The skin of the nose is very thin, and the blood vessels are close to its surface.
Vascular activity: The nose contains a large number of small blood vessels that respond quickly to any change in blood flow.
Repeated exposure: When alcohol is consumed excessively, the blood vessels in the nose are subjected to greater pressure than others, increasing the likelihood of redness.
