Just redness on the nose and a disease called "red nose" (rosacea) are two different things. "Red nose" is a consequence of an infection brought in by a tick (demodicos). At first, redness appears only at the very tip, and then covers the entire nose, spreads, if the disease is started, to the cheeks and even to part of the forehead. In a very short time, the entire nose will be covered with such a dense network of veins (tortuous veins), filled with blood, that it will acquire a bluish tint. It will begin to increase in volume and thicken, the sebaceous glands will grow, a greasy shine will appear, and the nose itself will resemble a pear in shape.
To get rid of redness on the nose, you must first of all find out that this is an ordinary vasodilation, which you can cope with yourself, or demodicosis, with which you should immediately go to the doctor.
Pay attention to your general condition. The fact is that things like anemia, colds, digestive disorders, stress or intense excitement, menstruation, can also cause redness of the nose. Another reason may be pustular inflammation of the hair follicles in the nostrils. And then the underlying disease should be treated, and the consequences - redness of the nose, will go away by themselves.
If redness is still caused by enlarged pores and local vascular disorders, reconsider your diet. Be aware that eating too much (overeating) will cause your blood to flush. Spicy foods, alcohol, too hot dishes, as well as tea and strong coffee sin the same.
You cannot protect yourself from sudden changes in the weather, when your nose turns red more than usual, but to harden your nose so that it reacts less is in your power. Do a couple of times a week baths or compresses from a decoction of sage or chamomile, alternating hot and cold and ending always cold. Also, don't go light in winter and avoid direct sun in summer. Before going out into the cold, grease your nose with melted goose / duck fat and powder.
For a nose that turns red from frost, make a decoction of lime blossom and wipe it in the morning and before bed (but not before going out into the cold!).
In the morning, standing at an open window, do nasal gymnastics: alternate a series of short and strong nasal breaths with the same series of exhalations.
Use room temperature water to wash your face. Then massage - gently pinch, tap and press with your fingertips.
