Why are the sides of my nose red

The sides of your nose being red could be due to a variety of reasons. It could be a result of cold weather, which can cause the skin to become red and chapped. It could also be due to skin conditions such as rosacea, which can cause redness and inflammation on the skin. Additionally, allergies or other skin irritations could also contribute to the redness. If the redness persists or is accompanied by other symptoms such as itching or burning, it is recommended to consult a doctor or dermatologist for proper diagnosis and treatment. In the meantime, you can try using a moisturizer to keep your skin hydrated and reduce redness.
