Esthetician (South Korea National Technical Qualifications in Barbering and Beauty) study guide

Esthetician · Work through your exam, one topic at a time.

An esthetician license is the credential a state issues to a practitioner who performs skin care services for the public-facials, cleansing and exfoliation, extractions, hair removal by waxing or depilation, makeup application, lash and brow services, and, where scope of practice allows, chemical peels and use of esthetic equipment. The licensing examination is one part of that state process; it confirms you know sanitation and infection control, skin science and anatomy, client consultation and contraindications, treatment protocols, and the business and ethics rules that apply in a salon or spa. The Esthetician study guide has 12 sections and about 3,106 words.
