What causes red nose?

In winter, because the weather is cold, many people will wear more clothes when going out, and cover themselves tightly. But if we expose our noses outside, we will find that our noses will be frozen red, and the sides will also turn red at this time. However, as long as it experiences a warm temperature, this phenomenon will disappear. If the red nose is caused by skin diseases, it must be treated in time. So what is the reason for the red nose?

Causes of redness on both sides of the nose

1. Seborrheic dermatitis

Seborrheic dermatitis is a common cause of redness on the sides of the nose.

Seborrheic dermatitis is prone to occur in areas rich in sebaceous glands such as the scalp, sides of the nose, eyebrows, eyelids, behind the ears, and the center of the chest. Sometimes rashes may also appear in the armpits and genitals.

The rash is characterized by redness of the skin and the appearance of yellow scales, sometimes thicker yellow-brown crusts and a tendency to moisture, and is not necessarily accompanied by itching. The disease usually occurs in infancy and middle-aged people between 30 and 60 years old.

2. Getting angry

When the internal heat is strong, the heat energy will rise up and cause redness on both sides of the nose, acne, etc.

3. Allergies

Allergies are a common cause of skin redness.

4. Blow your nose

When having a runny nose, some people like to blow their nose very hard, which can also cause the sides of the nose to be squeezed and become red.

5. Rosacea

Rosacea, also known as rosacea, rosacea and red nose, is a chronic inflammatory skin disease that occurs in the nose and mostly occurs in middle-aged people.

It usually manifests as redness of the skin on the outside of the nose, but is most noticeable at the tip of the nose. This is the result of significant dilation of the blood vessels, and sometimes the dilated small blood vessels can be seen through the skin in a tree-like shape.

It is a common skin disease, mainly caused by mite infection. 100% of rosacea patients can be found to have mite parasites.

Rosacea usually grows on the tip and wings of the nose. In hot weather, the nose will turn red and oily. In winter, the nose will peel and become painful.

The initial symptoms are redness, oiliness and brightness of the nose, which is often not easy to notice. Over time, the pores on the nose become larger and red papules and pustules appear. In severe cases, the tip of the nose becomes thicker and larger, and the epidermis becomes like orange peel, uneven, and ugly.

Due to the vigorous secretion of local sebaceous glands, the nose appears red and shiny. As the disease progresses, the skin may thicken and even develop rashes or small pustules.
