Business Practices, Professional Standards, and Wisconsin Laws and Rules
Scope is the big idea
In Wisconsin, esthetics is regulated by the Department of Safety and Professional Services (DSPS) under the cosmetology chapter of the Administrative Code. Both the individual practitioner and the establishment must be licensed, and licenses must be available for inspection. An esthetician's scope covers cosmetic services - facials, cleansing, exfoliation, extraction, waxing, makeup application, superficial peels within training - and stops at diagnosis and treatment of disease. If a service would diagnose, prescribe, or medically treat, refer out. Practicing outside licensure or on an unlicensed premises is a violation that can bring fines, suspension, or revocation.
Running the business
Know pricing (cost of goods plus time and overhead), retail markup, inventory control, scheduling and cancellation policies, informed consent, confidential client records, and professional liability insurance. Sanitation rules apply to the whole establishment, not just the treatment room. Continuing education is required for renewal on Wisconsin's biennial cycle - confirm the current hour and topic requirements in the rule before you renew, since those numbers change.
Professional standards
Be on time, disclose pricing and product use, obtain consent before touch or extractions, protect client privacy, never make medical claims for products, and document adverse reactions.
Rule of thumb: when a request feels like health care, it is outside your license - document, decline politely, and refer.
Trap: questions often describe a plausible-sounding service (e.g., "remove a mole," "treat an infection") that is legal only for a physician.
