I think many people think that being a beautician is harmful to health, either because they are worried that the product is not good and frequent contact will do harm to human body, or because beauticians will contact customers' bodies. Some people worry that bad diseases will be transmitted to beauticians. From a professional point of view, all qualified beauty salons use formal channels to purchase products, or some are independently developed, which has little impact on the human body in essence. On the contrary, beauticians often work hard and massage consumes energy, so some beauticians have some occupational diseases on their shoulders, necks, hands and waist. In fact, like most ordinary industries, beauticians should check regularly if they are really worried about physical problems, instead of generalizing when they see some extreme remarks.
