MN Esthetician case studies

MN Esthetician · Put your knowledge to work in context.

The Minnesota esthetician license is the credential that allows you to perform skin care services for pay in Minnesota - facials, cleansing and facial massage, hair removal by waxing and other depilatory methods, eyelash and eyebrow services, makeup application, and chemical exfoliation - under the oversight of the Minnesota Board of Barber and Cosmetologist Examiners. The licensing examination is the final gate before that license, and it is built to confirm two things at once: that you can reason through the science behind a service (skin anatomy, product chemistry, infection control) and that you can carry it out safely and legally in a working salon. The MN Esthetician case studies are 5 cases and about 5,169 words.

The Saturday Back-to-Back: Disinfection Judgement Under Time Pressure

You are the only esthetician on duty at a three-room salon on a Saturday with eight facials booked back-to-back. At 10:15 you notice five things at once: (1) the quat disinfectant spray bottle was mixed Friday, has no label, and the test strip reads about 100 ppm against the manufacturer's range of 200–400 ppm; (2) a stainless steel comedone extractor just slipped off the tray onto the floor; (3) a second extractor was used on a client's nose, wiped with an alcohol pad, and put back on the tray; (4) the autoclave log shows the last spore test was three weeks ago; (5) the wooden orange-wood stick you used to check a client's skin is still lying on the cart.

Booth Rent, a Minor, and a Peel She Isn't Licensed For

A Minnesota-licensed esthetician with four years at a chain salon is moving into a five-suite studio as a booth renter. Before her first client, the studio owner tells her: (a) she will be paid on a 1099 and must carry her own liability insurance; (b) the studio doesn't set hours, prices, or a menu - 'you run your own book'; (c) a 16-year-old has booked a series of 'medium-depth peels' after seeing the esthetician's Instagram ad; (d) the owner wants to repost the esthetician's before-and-after photos of a client's back acne; (e) the shared disinfectant in the treatment room is a blue liquid in an unmarked bottle that 'everyone uses.' The esthetician holds a basic esthetician license and has never checked whether medium-depth peels are within it.

Lash Lift and Brow Tint After a Previous Reaction

A 29-year-old client wants a brow tint plus a lash lift and lash tint six weeks before her wedding. She mentions, almost in passing, that at another salon four months ago 'my eyes swelled and itched for two days' after a tint - she thinks it was 'just the fumes.' She wears monthly contact lenses and takes a daily antihistamine for seasonal allergies.
