Why is skin disease high in autumn and winter? From internal and external factors.
The causes of dermatitis and eczema include internal and external factors. The so-called internal factors are the allergic constitution of patients themselves, which plays a leading role in the pathogenesis of eczema and dermatitis. The instability of the internal environment, such as chronic digestive system diseases, mental tension, insomnia, excessive fatigue, emotional changes and other mental changes, as well as infectious lesions, metabolic disorders and endocrine dysfunction, can induce or aggravate the condition of eczema and dermatitis.
There are many external factors, including inhalation, food, allergy and so on. Among them, seafood, spicy food, wine, inhaled pollen, dust mites, cold weather, contact with chemicals, soap and detergent are the most common causes of eczema and dermatitis.

3. Elixir: it is a preparation of drugs dissolved in alcohol. Commonly used are antipruritic elixir, ringworm potion, etc. After such drugs are applied, the therapeutic effect can be achieved due to the rapid evaporation of alcohol and the presence of antipruritic and peeling drugs in alcohol preparations. Because the drug has certain irritation, it should not be applied to the face, mucous membrane and infants, especially ringworm potion. Because it has strong stimulation and peeling effect, it must be carried out under the guidance of doctors.
4. Cold cream preparation: it is the most commonly used preparation in dermatology. It is very popular with patients because of its delicate and white appearance, like cosmetics. The commonly used cold cream preparations, in addition to the antipruritic cream with antipruritic drugs (such as Bishu cream) and urea cream (crack healing cream) to prevent skin moisture evaporation, the most common are all kinds of corticosteroid hormone creams (such as furelaxed, dexamethasone, triamcinolone, fule, etc.),
5. Ointment: its main ingredients are lanolin and vaseline. Because the ointment is greasy, it has been gradually replaced by cold cream preparation.

Its effect on some keratosis and chronic skin diseases (such as plaque silver filings and severe chapped, etc.) is better than that of cold cream preparation. Commonly used ointments such as compound benzoic acid ointment, sulfur ointment Mustard gas ointment, etc.
6. Hard paste and coating preparation: This is an improved external drug preparation in recent years. It adds drugs to adhesive tape or film preparation. After coating, the film is isolated from the external air, which is convenient for drug absorption and avoids the disadvantages of drug loss due to clothing friction. Commonly used preparations such as fucining, Zigui crack treatment ointment, hydrogen coating, skin treatment film, etc. However, some patients may be allergic to the hard paste preparation. Of course, the preparation containing corticosteroids is easier to absorb than other preparations, but we should pay attention to the side effects caused by excessive absorption.
Xiaobian warm tips: do not use hormone external drugs casually. Hormone drugs have large side effects and should not be used for a long time.
