The skin of nose is troublesome. In summer, there is a lot of oil. But in autumn and winter, there is dry skin around nose. So, the nose often feels rough to the touch, like a lot of thorns are present on it. This disease is really common, the diagnosis is very clear. The Disease is seborrheic dermatitis.
What is its pathogenesis?
The specific cause of it is not yet known. Dry skin around nose is not the same as acne, it is not a sebaceous gland disease, and the patient’s sebum excretion rate does not increase.
But despite this, sebaceous glands seem to be inseparable from seborrheic dermatitis, because the lesions basically occur in areas with a large number of sebaceous glands and large sebaceous glands, such as the sides of the nose, eyebrows, external auditory canal, scalp and other parts.
Causes of Dry skin around nose:
The change of seasons. The change of seasons can cause Dry skin around nose. Sensitive skin is more likely to appear at the change of seasons, causing skin allergies and a series of problems, such as dry skin. Therefore, when changing the seasons, you should pay attention to the use of anti-allergic skin care products to wipe, may improve the problem of dry skin.
The skin is dehydrated. In daily life, not paying attention to skin care or drinking less water may also cause dry skin. It may also be due to aging that reduces sebum secretion, which leads to a decline in water retention capacity. Therefore, in daily life, you should pay attention to skin care, drinking water, and choose anti-aging skin care products to keep your skin alive.
Is seborrheic dermatitis necessarily seen in oily skin, is it a patent for oily skin?
The answer is no. In fact, many patients with seborrheic dermatitis often have dry skin and desquamation.
So what exactly do sebaceous glands do in the onset of seborrheic dermatitis?
Some scholars speculate that the sebaceous glands may play a role in creating a favorable environment for the growth of Malassezia.
Does seborrheic dermatitis need to be tested for Malassezia?
It doesn’t make much sense, because Malassezia is a lipophilic (relying on sebum) microorganisms and is a component of normal skin flora.
Seborrheic dermatitis also recurs seasonally, accompanied by small red papules/backlight rash and greasy scales on the epidermis. This picture does not look very greasy. Seborrheic dermatitis is also more headache and difficult to cure. There are many causes of seborrheic dermatitis, not necessarily as the excessive seborrhea mentioned above, and some studies believe that it is related to the quality or proportion of sebum.
Use gentle cleansing:
You can use it for normal skin, such as Dove Moisturizing Cleansing Mousse/Hada Labo Extremely Moisturizing Cleansing Foam/Dabao Hydrating Moisturizing Cleansing Milk/Affordable Herbal Core Net Natural Amino Acid Foaming Cleansing Milk and so on. Similarly, if there are tingling pustules in the nose, reduce the frequency of cleansing. The original gentle cleansing may become ungentle.
Control oil and repair skin barrier:
Seborrheic dermatitis will also be accompanied by damage to the skin barrier. Using some oil control and soothing products will improve the current situation.
At present, the sides of the nose are slight and do not need medicine at all. Skin care products have an auxiliary effect. If seborrhea is severe, you need to take spironolactone, short-acting contraceptives, and B6 to control oil under the guidance of a doctor. More seriously, you need oral isotretinoin, topical tacrolimus, and metronidazole. Gel, compound cod liver oil zinc oxide ointment, weak hormone ointment desonide, etc. The effect of medication is much faster than the above skin care products.
1. External hormone drugs, generally choose weak external hormone ointments, such as hydrocortisone, desonide, until the symptoms improve, and then slowly reduce the amount to maintain. It is estimated that when it comes to hormones, many people’s heads are like turnips. In fact, any drug has certain risks, as long as the use of hormone drugs is relatively safe.
2. If you are really against hormone drugs, you can also choose calcineurin inhibitors, such as 0.03% tacrolimus and 1% pimecrolimus, use it once a night, there may be slight stimulation and Scorching, generally can be tolerated after 3-5 days of continuous use.
1. 2% ketoconazole cream or other azole drugs, 1-2 times a day.
2. Selenium disulfide lotion or ketoconazole lotion, use 2-3 times a week.
3. 1% ciclopirox cream, 1-2 times a day.
4. For heavier or more difficult to treat, oral antifungal drug, itraconazole (it is recommended to use the drug under the guidance of a doctor).
Pay attention to sun protection
For example, sun exposure will aggravate oil production, and squalene in sebum will be oxidized during sun exposure. This peroxidation product has a strong pro-inflammatory effect and will aggravate inflammation. Patients with acne should also pay attention to sun protection. If you can’t do daily sun protection, avoid strong ultraviolet rays.
Generally speaking, seborrheic dermatitis on both sides of the bridge of the nose is relatively mild and can be resolved easily. Don’t use acne needles to shave your nose. This will also cause mechanical damage to the skin, whether it is blackheads in the nose or white in the nasal grooves. There is no way to solve the secretion of grease, unless the grease is no longer secreted.
Seborrheic dermatitis usually begins in adolescence and adulthood, and has a process of alternating relapse and remission during life. Even after successful treatment, recurrence is common, so follow-up maintenance treatment is very critical.
Supplement enough water
Develop a habit of drinking plenty of water, so as to prevent dry skin. Choose boiling water, take the principle of small amounts and multiple times. Wake up every morning and drink a cup of honey water to nourish the yin and nourish lungs. Drink a cup of warm water at lunch can moisturize and anti-oxidize. Drinking a cup of warm water at 17:00 can replenish moisture and help digestion.
Carrots are rich in β-carotene, which will be converted into vitamin A after being absorbed by the body, which has the effect of moisturizing the skin, making the skin more shiny, elastic and anti-aging.
The appearance of scaly and peeling skin does not mean that dryness requires heavy moisturization.
The appearance of red blood streaks on the skin does not mean that sensitive skin products need to be used.
If you use products with heavy fat content at this time, such as some baby products, olive oil products, etc., you may be fed a large amount of Malassezia. This fungus feeds on oil and loves to eat oil, which leads to Malassezia. The chromo bacteria multiply and aggravate the condition.
