There are two possible cases of facial fever with a mask, the mask or the serum composition contained irritants, resulting in irritating skin fever. If the symptoms are mild, no other discomfort, and soon relieved, the problem is usually minor and does not require special disposal, but it is best not to use such masks again. It may be that one is sensitive to a certain ingredient of the mask and the allergy occurs. If there is no skin redness, swelling or oozing, there is no need for special treatment, just choose a mask that suits your skin type. If after applying the mask, not only the face appears hot, but also a series of skin problems, or accompanied by itching and other uncomfortable feelings, all need to immediately wash off the facial serum. Further treatment such as desensitization and anti-itching may be required and will need to be guided by a clinician after an interview.
