Which of the following modalities is NOT used in esthetics?

The choice of magnetic as the modality that is not used in esthetics is accurate because magnetic therapy is generally considered more of a complementary or alternative treatment, focusing on the use of magnetic fields for pain relief and healing rather than being a standard modality for skin care. In esthetics, techniques are primarily focused on improving skin texture, enhancing appearance, and facilitating various skin treatments.

Galvanic, faradic, and sinusoidal modalities, on the other hand, play significant roles in esthetics. Galvanic, for instance, utilizes electrical currents to facilitate chemical processes in the skin, often used for deep cleansing and product penetration. Faradic current is employed for muscle-toning and improving facial contours, while sinusoidal currents provide relaxing effects and enhance blood circulation. These methods are widely recognized and practiced within esthetic settings for their specific benefits in skin care and cosmetic applications.
