When performing a facial treatment with a device, the esthetician should always follow:

• A. Manufacturers directions
• B. Personal preference
• C. General salon practice
• D. Random guidelines

Answer: (A)

Using a device safely and effectively means following the manufacturer's directions. Those guidelines are based on the device’s tested safety data and designed parameters, so they specify exactly how to set and use the device, including intensities, treatment times, and which areas are safe to treat. They also outline necessary precautions, contraindications, and steps like patch testing, cleaning, disinfection, and maintenance. When you follow these directions, you’re protecting the client’s skin from irritation or burns, ensuring you deliver the intended results, and keeping the device performing correctly (including proper calibration and compatible accessories). While good salon practice and professional judgment matter, they don’t replace what the device manufacturer specifies, which should always guide use.
