What causes redness under the nose in winter

The cause of redness under the nose in winter can be attributed to several factors. One of the most common reasons is the low temperature and dry air in the environment. When the air is cold and dry, it can cause the blood vessels under the skin to become more visible, resulting in a red appearance. Additionally, in winter, people tend to use hot water to wash their faces, which can also lead to redness under the nose. The hot water can irritate the skin and cause it to become red. Furthermore, certain skin conditions may also contribute to redness under the nose during winter. For example, rosacea is a common skin condition that can cause redness and visible blood vessels on the face, including under the nose. To prevent redness under the nose in winter, it is recommended to use a gentle cleanser and moisturizer to protect the skin from the dry air. Additionally, avoiding excessive exposure to cold air and using a humidifier can also help to alleviate this issue. If the redness persists or becomes uncomfortable, it is advisable to consult a doctor or dermatologist for further evaluation and treatment options.
