Product description
In the teaching process of Blackboard, teachers will inevitably get chalk dust on their hands. At the same time, particles floating in the air will also fall on the teacher’s hair, face and neck, irritating the skin membrane. If it is hydrolyzed by sweat in the summer to produce alkaline substances, it will irritate the skin and mucous membranes even more, because the environment of human skin is a weakly acidic environment, which destroys the basic living environment of the skin. Dust has an alkaline effect, and chalk dust makes the skin dry and rough, accompanied by itching, which makes the human body uncomfortable. In severe cases, it can cause acne, folliculitis, pyoderma, chapped skin, and massive hair loss, which affects and interferes with the normal work and life of teachers.
