1. Professional professional ethics: As a male skin care teacher, his duty is to provide professional skin care consultation and nursing services to customers. Male skin care teachers also understand that work and personal feelings should be separated, so they should maintain a professional and objective attitude to ensure the maximum satisfaction of customers' interests.
2. Avoid unnecessary troubles: At work, skin care teachers need to deal with many customers. If they have a good impression on a customer, it will affect the efficiency and judgment of skin care, thus affecting the quality of service. In order to avoid this situation, male skin care teachers will choose to avoid having too much personal feelings for customers.
