Whether or not skin allergies can heal on their own depends on the severity of the condition, which usually takes about 2 weeks, or a few days for some mild cases. However, if the condition is more serious, systematic treatment is needed to cure it. Self-healing refers to the use of the body’s self-repairing ability to achieve a state of healing without any medication or other treatment. Some patients with mild skin allergies can regulate the allergic reaction through the body’s own secretion of anti-allergic substances to achieve the purpose of self-healing. But for skin allergy patients, most need to receive treatment. If after 1-2 days of observation patients still have no trend of self-healing, or even aggravation of symptoms, it is recommended to consult a doctor in time to rule out the possibility of some serious diseases. At the same time should also follow the doctor’s instructions for medication, such as oral cetirizine tablets, imipramine tablets, topical hydrocortisone ointment, mometasone furoate cream and so on, in order to improve the symptoms of allergy, to avoid further aggravation of the condition. In addition, skin allergy patients need to pay attention to do not stay up all night, eat less or do not eat seafood and other foods that are easy to trigger skin allergies, and pay attention to avoid direct sunlight and ultraviolet radiation stimulation during the recovery period.
