Introduction
Facial itching may be caused by physiological factors or pathological conditions such as contact dermatitis and seborrheic dermatitis, and can be treated through general management or medication. When seasons change and temperature fluctuations are significant, the patient's skin may become irritated, leading to itching. It is important to drink plenty of water and promptly replenish the body's needed fluids.
Facial itching may be caused by physiological factors, or by pathological conditions such as contact dermatitis or seborrheic dermatitis. Treatment can be achieved through general management and medication. Specific details are as follows:
I. Physiological Factors
During seasonal changes, large fluctuations in temperature may irritate the skin and lead to itching. It is important to drink plenty of water to maintain adequate hydration in the body.
II. Pathological Factors
1. Contact Dermatitis
If a patient comes into contact with allergens such as pollen or mites, these substances may enter the body, promote the release of catecholamines, increase skin permeability, trigger rashes, and cause skin itching. Under medical guidance, topical treatments such as triamcinolone acetonide and econazole nitrate cream or compound acetic acid dexamethasone cream may be applied.
2. Seborrheic Dermatitis
This condition is associated with increased sebaceous gland secretion, impaired skin immune barrier, and individual immune responses, leading to dilation of skin capillaries, accompanied by symptoms such as pain and itching. Under medical supervision, treatment may include topical application of compound acetic acid dexamethasone cream or oral administration of vitamin B2 tablets.
In addition to the above causes, facial itching could also result from urticaria, eczema, systemic lupus erythematosus, and other conditions.
