What should I do about very dry skin?

Generally, very dry skin may be related to factors such as dry climate, improper cleansing, chronic dermatitis, psoriasis, and Sjögren's syndrome. If discomfort occurs, it is recommended to seek timely treatment at a reputable hospital. Detailed analysis is as follows:

1. Dry Climate: In cold, dry environments, moisture from the skin can easily evaporate, leading to dry skin. It is recommended to use a humidifier to increase indoor humidity and avoid staying in dry environments for prolonged periods.

2. Improper Cleansing: Using overly alkaline cleansing products, bathing with excessively hot water, or bathing too frequently can damage the skin's natural barrier, accelerating moisture loss and causing dryness. It is recommended to maintain moderate cleansing, avoid using hot water and irritating cleansers, and apply moisturizing products such as vitamin E cream or silicone oil emulsion immediately after bathing.

3. Chronic Dermatitis: Chronic dermatitis is mainly caused by nonspecific inflammation. Due to impaired skin barrier function, the skin becomes more susceptible to external irritants and infections, leading to dryness, possibly accompanied by symptoms such as redness and itching. It is recommended to follow medical advice to use medications such as compound glycyrrhizin tablets, peony phenol ointment, mometasone furoate cream, etc., for relief.

4. Psoriasis: Psoriasis is an autoimmune disease. Psoriasis can cause thickening of the stratum corneum and impaired skin barrier function, leading to moisture loss and dry skin, which may be accompanied by red patches, scales, and other symptoms. Under a doctor's guidance, medications such as calcipotriol ointment, tacalcitol ointment, tazarotene gel can be used for improvement.

5. Sjögren's Syndrome: Sjögren's syndrome is a chronic autoimmune disease in which the patient's immune system may attack its own exocrine glands, leading to reduced secretory function of salivary and lacrimal glands. The skin lacks necessary hydration and becomes dry, possibly accompanied by symptoms such as dry mouth and dry eyes. After consulting a doctor, medications such as methotrexate tablets, cyclophosphamide tablets, azathioprine tablets can be used for symptom relief.

If symptoms continue to worsen, it is recommended to seek timely treatment at a reputable hospital to avoid delays in treatment. In daily life, pay attention to skincare and avoid long-term exposure to ultraviolet radiation to prevent skin damage.
