The use of Personal Protective Equipment (PPE) such as masks, face shields, and gowns is essential to protect both clients and staff from potential exposure to pathogens, especially during close-contact treatments. PPE should be worn during all procedures and changed between clients to ensure maximum protection. This practice is particularly important in preventing the spread of infectious diseases and maintaining a safe, sterile environment. PPE use is a standard precaution that enhances the overall hygiene and safety of the spa.
