Female pedicurists usually protect themselves for two hours. Female foot massage technicians generally need to protect themselves every two hours. Because the work of foot massage needs to stand for a long time and touch the skin of guests, technicians are easily exposed to various environmental risks. Therefore, in order to protect themselves and their guests' health, female technicians need to take self-protection measures regularly, such as washing hands, changing work clothes and sheets, cleaning and disinfecting the working environment, etc. Self-protection every two hours can effectively reduce the potential risk of infection and protect the health of technicians and guests.
