Beauty therapists are the core link between brands and consumers, and their capabilities directly determine service quality. Professionally, they need to master systematic skin knowledge, accurate skin diagnosis skills and standardized operation techniques—establishing a closed service loop from diagnosis and plan customization to implementation and effect tracking. They should also have in-depth understanding of product ingredients and effects to provide scientific recommendations. In terms of communication, they should abandon sales-oriented thinking and adopt a consultative approach: use open-ended questions to explore user needs, listen patiently and respond empathetically. For example, when a user complains about poor skin after staying up late, respond with understanding and focus on providing soothing solutions. Customer relationship management requires establishing detailed user files, recording skin conditions and preferences, and maintaining regular interactions (e.g., post-service follow-ups, holiday greetings) to strengthen emotional bonds. Additionally, strict adherence to hygiene standards and tool disinfection procedures is essential to ensure service safety.
