Makeup must not be applied when there is an allergy on the face. At this time, the face will have obvious itching and even redness, swelling and peeling, and some patients may also have local skin breakage, bleeding or exudation. If makeup is applied at this time, it may aggravate the symptoms of skin allergy and may also induce skin inflammation infection. In this case, it is important to apply saline or blue skin nourishing wet compresses to relieve local inflammation and moisturize the skin. Oral anti-allergy medications and antihistamines, such as loratadine, cetirizine and paracetamol, can be taken. When the face is allergic, if the patient has a water cream with simple ingredients, it can be applied; if it is a daily skin care product, try to stop using it.
