With the arrival of spring, the number of patients with facial dermatitis increases, and doctors will diagnose many names based on your specific condition, such as contact dermatitis, facial reoccurring dermatitis, seasonal dermatitis, cosmetic dermatitis, dyed hair dermatitis, and so on. In fact, this is a large group of skin allergic (allergic) diseases, and the principles of treatment are roughly the same. So, what should patients with facial dermatitis pay attention to? The first thing is to have a proper understanding of the course of the disease. Facial dermatitis is basically an allergic inflammatory process that generally takes 7 to 14 days to subside, so it is not right to rush through the treatment. Secondly treatment should be based on internal anti-allergy and anti-inflammation. Any blind topical medication, especially irritating alcohol-based preparations or corticosteroid-based topical medications, is inappropriate and may aggravate or prolong the condition. If there is a genuine need, such as in the case of exudation, a more gentle solution applied wet (e.g. saline, etc.) should be applied under medical supervision. For flaking and dry skin, some mild protective agents (e.g. silicone creams, etc.) should also be applied under the guidance of a doctor, but they should be tried before application to make sure there are no adverse reactions before applying them on a large scale. Diet should be strictly abstained from eating spicy and stimulating food, keep sufficient sleep, and avoid scratching with hands. Finally, since the face is exposed all day long and receives a lot of stimulation from many biological and physical factors, the disease is somewhat unpredictable, so if changes occur after the use of medication, you should consult a doctor promptly and require the help of a doctor. In addition, for recurrent facial allergic diseases, appropriate allergen testing, such as patch testing, should be done to find the cause of the disease and facilitate prevention and treatment.
