Why should technicians wear protective gear during microdermabrasion treatments?

Wearing protective gear during microdermabrasion treatments is essential primarily to prevent inhalation of nuisance dust. During this procedure, the microdermabrasion machine exfoliates the skin by using abrasive crystals or diamonds to remove dead skin cells. This process generates fine particles and dust that can become airborne. If technicians are not properly equipped with masks and other protective gear, they risk inhaling these particles, which could lead to respiratory issues or irritation.

In addition to protecting the respiratory system, using protective gear helps to maintain a safe and sanitary environment. While preventing contamination is also a crucial aspect of wearing protective equipment, which includes gloves and eye protection, the specific concern addressed by the correct answer is the inhalation of dust created during the treatment. Comfort and aesthetic concerns are secondary to the primary health and safety risks posed by exposure to these airborne particles.
