The topic is to ask the reason why Qizibai mask is extremely harmful. The reason why Qizibai mask is extremely harmful is because of allergic problems. The main components of Qizibai mask include Atractylodes macrocephala, Angelica dahurica, Bletilla striata and other Chinese herbal medicines. These ingredients are non-toxic and have certain effects, such as whitening and removing spots. However, due to different skin types, some people may be allergic to these ingredients, and allergic reactions such as itching, redness and tingling may occur after use. For people with sensitive skin, the risk of using Qizibai mask is greater. In addition, long-term use of Qizibai mask may lead to problems such as dry skin, clogged pores, and skin discomfort. If these adverse reactions occur, stop using them immediately and consult a doctor.
