Recently, there has been a significant increase in the number of patients with facial dermatitis visiting the dermatology department. This is because of the changeable temperature and dry and windy spring, which is very damaging to human skin, especially the exposed facial skin. The loss of skin moisture and lack of protection can lead to a decrease in skin resistance, which can easily be stimulated by foreign objects and lead to facial dermatitis. The common facial dermatitis are seasonal contact dermatitis, facial reoccurrence dermatitis, periorbital (periorbital) dermatitis, hormone dependent dermatitis, etc. Whatever the dermatitis, do not just apply topical creams. Hormone-dependent dermatitis is caused by irregular or long-term topical use of corticosteroids, especially strong fluorogenic hormones. Therefore, once the facial erythema, papules, edema or dryness, flaking, etc., accompanied by itching, tightness or burning sensation, you should promptly go to the regular hospital for treatment, do not aggravate the condition because of inappropriate medication, resulting in recurrent dermatitis. We use negative air ion spray with topical and oral medication to treat facial dermatitis, which is safe and effective and has a good protective and regulating effect on the skin and can effectively inhibit the recurrence of facial dermatitis.
