For facial allergies, the first thing people need to do is to have some basic knowledge and raise awareness of self-care.
If you know what clear allergens you have, you should try to avoid them in your life. If you cannot avoid them, such as dust allergy, you can try desensitisation therapy under the guidance of a doctor, and patients should pay attention to exercise and moderate sun exposure in general, and their diet should also pay attention to avoiding irritating foods, etc., through a combination of measures and joint prevention.
